How would one use a [Wicket] ListView with a form? - wicket

I have added a Form on submit of which I have to add more wicket controls like Labels, textfields and button with an Ajex Link. But not able to get the correct HTML. Can anyone please help me to get rid of it ?
voucherPanel.html
<html xmlns:wicket>
<head>
</head>
<body>
<wicket:panel>
<div class="form-block">
<div wicket:id="form">
<wicket:message key="lbl.vouchercode" />
<div wicket:id="list">
<input wicket:id="word" type="text" />
</div>
<div wicket:id="vouchercode"></div>
<button wicket:id="submit"><wicket:message key="submitText"/></button>
</div>
</div>
</wicket:panel>
</body>
</html>
voucherPanel.java
public class VoucherPanel extends Panel
{
private static final long serialVersionUID = 1L;
public VoucherPanel(final String id)
{
super(id);
final TextField<String> voucherCodeField = new TextField<String>("vouchercode", Model.of(""));
voucherCodeField.setRequired(true);
final Button button = new Button("submit");
Form<?> form = new Form<Void>("form")
{
#Override
protected void onSubmit()
{
numberOfFields = new ArrayList<String>();
int noOfVocuhers = getNoOfAllowedVoucher();// just returing the number
for (int i = 0; i < noOfVocuhers; i++) {
numberOfFields.add(new String(""));
}
add(new ListView<Object>("list", numberOfFields) {
private static final long serialVersionUID = 1L;
#Override
protected void populateItem(ListItem<Object> item) {
final String word = (String) item.getModelObject();
System.out.println( "word =" +word );
TextField<String> textField = new TextField<String>("word", Model.of(""));
textField.setOutputMarkupId(true);
item.add(textField);
}
});
}
}
};
add(form);
form.add(voucherCodeField);
form.add(button);
}
}

You're trying to assign a Textfield to a <div> element (voucherCode), you need <input type="text"> instead.
You need to add list to your form right away, onSubmit is too late. Just set it outside, similar to button and call myListView.setList when submitting the form.
These are the two things I spotted... if you still have problems please let us know about the error messages you get.

Menu building - Wicket framework

I am building a two-level menu for my application using wicket framework. Using ListView#populateItem is redrawing the markup (SubMenuPanel.html) and unable to display menu items which were buried inside markup tags in SubMenuPanel.html. Code below -
html:
<div wicket:id="navMenu"></div>
Main.java:
NavigationMenu navigationMenu = new NavigationMenu("navMenu", navigationMenuAdapter);
add(navigationMenu);
NavigationMenu.java
public NavigationMenu(final String id, final NavigationMenuAdapter adapter)
{
super(id);
this.adapter = adapter;
add(new SubMenuPanel("mainMenu", adapter.getNavigationMenus(this)));
}
SubMenuPanel.java
public SubMenuPanel(final String id, List<NavigationMenuItem> list)
{
super(id);
add(new Rows("firstLevel", list));
setVersioned(false);
}
private static class Rows extends ListView<NavigationMenuItem>
{
private static final long serialVersionUID = 1L;
public Rows(String name, List<NavigationMenuItem> list)
{
super(name, list);
}
#Override
protected void populateItem(ListItem<NavigationMenuItem> listItem)
{
Object modelObject = listItem.getDefaultModelObject();
WebMarkupContainer rowAnchor = new WebMarkupContainer("firstLevelLink");
rowAnchor.add(new Label("firstLevelLabel", ((NavigationMenuItem) modelObject).getName()));
rowAnchor.add(new AttributeAppender("onclick", new Model("handleMenuClick()");
listItem.add(rowAnchor);
listItem.add(new SubMenuPanel("secondLevelMenu", ((NavigationMenuItem) modelObject).getChildMenuItem()));
}
}
SubMenuPanel.html
<body>
<wicket:panel>
<li wicket:id="firstLevel">
<a wicket:id="firstLevelLink" class="dropdown-toggle" aria-expanded="true" data-toggle="dropdown" href="javascript:void(0);" >
<span wicket:id="firstLevelLabel"></span>
</a>
<ul wicket:id="secondLevelMenu" class="dropdown-menu">
</ul>
</li>

Breadcrumb in AEM 6

I have a requirement to create breadcrumb in sightly. I have following code which is working fine in JSP. But i am struggling to convert the code to sightly because i am not getting the right methods in currentStyle object to get the "absParent" and others. Any help will be highly appreciated!!
<%# include file="/libs/foundation/global.jsp" %>
<%
final int startLevel = currentStyle.get("absParent", 3);
final int endLevel = currentPage.getDepth() - currentStyle.get("relParent", 0);
final int minItems = currentStyle.get("minItems", 2);
if (startLevel <= endLevel - minItems) {
%><section class="breadcrumbs"><%
for (int level = startLevel+1; level < endLevel; ++level) {
Page itemPage = currentPage.getAbsoluteParent(level);
if (itemPage == null || !itemPage.isValid() || itemPage.isHideInNav()) {
continue;
}
final String pagePath = itemPage.getPath() + ".html";
final String pageTitle = itemPage.getNavigationTitle();
String className = "breadcrumb-item-"+level;
if (level == startLevel) className += " breadcrumb-first";
if (level == endLevel-1) className += " breadcrumb-last";
pageContext.setAttribute("className", className);%>
<section class="breadcrumbs ">
<%= xssAPI.encodeForHTML(pageTitle) %>
</section>
<%} %>
</section><%
}
%>
To create breadcrumb you have to write a WCMuse class and include that in this component.
<div
data-sly-use.breadcrumb="${'com.mySite.components.BreadcrumbUse'}">
<!-- + Breadcrumb component + -->
<div class="breadcrumb component">
<div class="breadcrumb_nav_bar clearfix"
data-sly-test="${breadcrumb.navList}"
data-sly-list.element="${breadcrumb.navList}">
<p data-sly-test="${!elementList.last}">
<a href="${element.path}.html">${element.title ||
element.navigationTitle || element.name}</a>
</p>
<p data-sly-test="${elementList.last}">${element.title ||
element.navigationTitle || element.name}</p>
</div>
</div>
<!-- - Breadcrumb component - -->
</div>
Code Sample for WCMUse class:
Public class BreadcrumbUse extends WCMUse
{
private List<Page> navList = new ArrayList<Page>();
#Override
public void activate() throws Exception
{
setBreadCrumbItems();
}
private void setBreadCrumbItems()
{
long level = 4L;
long endLevel = 1L;
int currentLevel = getCurrentPage().getDepth();
while (level < currentLevel - endLevel)
{
Page trailPage = getCurrentPage().getAbsoluteParent((int) level);
if (trailPage == null)
{
break;
}
this.navList.add(trailPage);
level++;
}
}
public List<Page> getNavList()
{
return this.navList;
}
}
The below code will work for creating breadcrumbs in AEM6.2 using Javascript and HTL(previously sightly).It worked well for me..here we go
Javascript to be used in the server side script(it can also be created using java)
script.js
use(function () {
var title = currentPage.getTitle();
//To get the title of the current page
var level = currentPage.getDepth();
//To find the depth of the current page from the root
var cts = new Array();
// To store the traversed page (object) from the root
for(var i=1;i<level;i++)
{ // Here I used i=1 for mycase(i=0 will be /content)
var titl = currentPage.getAbsoluteParent(i);
//To get the absolute parent at each level from root
pageStack.push(titl);
//Stack to maintain the pages
}
return {
title: title,
pageStack:pageStack
};
});
Breadcrumbs.html
<sly data-sly-use.cpt="script.js">
<h1>${cpt.title}</h1>
<div data-sly-list="${cpt.pageStack}">
<span> ${item.title}/</span>
</div>
</div>
Thus we get the breadcrumbs ready for our presentation!!!

Wicket submit action doesn't work

After updating Wicket from version 6.12 to 6.13/6.14 onSubmit action doesn't work. For Example class:
public class LoginPage extends WebPage {
private String username = "";
private String password = "";
public LoginPage() {
super();
Form<?> form = new Form<Void>("form");
setDefaultModel(new CompoundPropertyModel<>(this));
form.add(new Button("submit") {
#Override
public void onSubmit() {
System.out.println("SUBMIT "+username+":"+password);
}
});
form.add(new TextField<String>("username").setRequired(true));
form.add(new PasswordTextField("password").setRequired(true));
add(form);
}
}
with HTML:
<!DOCTYPE html>
<html xmlns:wicket>
<body>
<form wicket:id="form">
<input id="name" type="text" placeholder="Username" wicket:id="username">
<input id="password" type="password" placeholder="Password" wicket:id="password">
<input type="submit" wicket:id="submit" value="Enter">
</form>
</body>
</html>
doesn't works with wicket version 6.13+ and great work with wicket 6.12-. Changing Button on something like SubmitLink doesn't help.
Could you tell me what's wrong?
Well... hacky but it seems to work with 6.15.
Replace encodePageComponentInfo with the following one.
#Override
protected void encodePageComponentInfo(Url url, PageComponentInfo info) {
Args.notNull(url, "url");
if (info != null) {
String s = info.toString();
if (!Strings.isEmpty(s)) {
try {
Integer.parseInt(s);
} catch (Exception e) {
QueryParameter parameter = new QueryParameter(s, "");
url.getQueryParameters().add(parameter);
}
}
}
}
I found problem in my test project. I use changed MountedMapper for hiding version number in the URL:
/**
* Wrapper for hiding the version number in the URL
*/
public class SimpleMountedMapper extends MountedMapper {
public SimpleMountedMapper(String mountPath, Class<? extends IRequestablePage> pageClass) {
super(mountPath, pageClass, new PageParametersEncoder());
}
#Override
protected void encodePageComponentInfo(Url url, PageComponentInfo info) {
}
public Url mapHandler(IRequestHandler requestHandler) {
if (requestHandler instanceof ListenerInterfaceRequestHandler) {
return null;
} else {
return super.mapHandler(requestHandler);
}
}
}
In new version of wicket something wrong with this implementation (got it from this question).

Reusing wicket component in a form

I have built a wicket component that contains input/labels and methods to change presentation (required, enabled, etc.). The components render fine, but what happens is when the form submits I see only 1 form parameter 'input', and it's the last InputRow component.
InputRow.html
<html xmlns:wicket="http://wicket.apache.org">
<head>
<link rel="stylesheet" type="text/css" href="style.css"/>
</head>
<body>
<wicket:panel>
<label wicket:id="label">abc: <span class="req">*</span></label>
<span class="input">
<input wicket:id="input" type="text" id="name"></input>
</span>
<span wicket:id="input_feedback"></span>
</wicket:panel>
</body>
</html>
InputRow.java
package com.wicket;
import org.apache.wicket.behavior.AttributeAppender;
import org.apache.wicket.feedback.FeedbackMessage;
import org.apache.wicket.markup.html.basic.Label;
import org.apache.wicket.markup.html.form.TextField;
import org.apache.wicket.markup.html.panel.Panel;
import org.apache.wicket.model.Model;
public class InputRow extends Panel{
#SuppressWarnings("unused")
private String id;
public InputRow(String id, String label) {
super(id);
this.id = id;
Label memberIdLabel = new Label("label",label);
memberIdLabel.setEscapeModelStrings(false)
.add(new AttributeAppender("for", new Model<String>(id),""));
add(memberIdLabel);
TextField<String> name = new TextField<String>("input");
name.setType(String.class)
.setMarkupId(id)
.setOutputMarkupId(true);
add(name);
add(new Label("input_feedback",""));
}
public InputRow disable()
{
get("input")
.setEnabled(false)
.add(new AttributeAppender("class", new Model<String>("disabled"),""));
get("label")
.add(new AttributeAppender("class", new Model<String>("disabled"),""));
return this;
}
public InputRow required()
{
Model model = (Model)get("label").getInnermostModel();
StringBuffer label = new StringBuffer((String)model.getObject());
label.append(" <span class=\"req\">*</span>");
model.setObject(label);
((TextField)get("input")).setRequired(true);
return this;
}
#Override
protected void onBeforeRender() {
super.onBeforeRender();
Label feedback = (Label)get("input_feedback");
if (get("input").getFeedbackMessage() != null)
{
feedback.setDefaultModel(new Model<String>("Required"));
}
}
}
Adding to the form component
add(new InputRow("name","Name:").required());
edit
I didn't set up a ListView or repeater since I know what rows / fields I want to add to the form at build time.
Your InputFields are missing their models. This way, wicket doesn't know where to store the formdata. If you add models to the fields they will be populated automatically.
There's not just one form parameter submitted. The submits are of the named like name:input, name2:input, ...
But as Nicktar suggests in the comment you should use a model to bind the value of the form component to your entity object. You have to accept an IModel in the constructor and use it in the constructor of TextField.
A better approach to what you are trying to do is to write a Behavior which adds decorating markup for your FormComponent. That way it works for more than just simple text input fields and you can fully customize the instances of your FormComponents.
It could look like this:
public class FormComponentBehavior extends Behavior {
#Override
public void bind(Component component) {
if (!(component instanceof FormComponent)) {
throw new IllegalArgumentException();
}
}
#Override
public void beforeRender(Component component) {
FormComponent<?> fc = (FormComponent<?>) component;
Response r = component.getResponse();
r.write("<label" + (fc.isRequired() ? " class='required'" : "") + ">");
r.write(fc.getLabel().getObject());
r.write("</label>");
r.write("<span class='input'>");
}
#Override
public void afterRender(Component component) {
component.getResponse().write("</span>");
// if feedback errors write them to markup...
}
}
Then you have to add this behavior to your FormComponent instances.
Maybe the problem with your form is that your input text fields have all the same id. Try using attribute 'name' instead of 'id'

Feedback panel added but does not show all messages

I have some basic form when you type email, old password, new password and repeat new pass for your profile modify. What I'm trying to achive is to display feedback msg when pass is wrong. A piece of code looks like this:
public class EditProfileForm extends Form<Void>
{
private static final long serialVersionUID = 1L;
// El-cheapo model for form
private final ValueMap properties = new ValueMap();
private ModalWindow modalWindow;
#SpringBean
UserManager userManager;
#SpringBean
Validator validator;
private User user;
private static final String EMAIL = "mp-email";
private static final String OLD_PASS = "mp-oldpass";
private static final String NEW_PASS = "mp-newpass";
private static final String NEW_PASS_REPEAT = "mp-newpassrepeat";
private static final String ERROR_WRONG_PASS = "Wrong pass";
private static final String ERROR_PASS_DIFF = "Pass diff";
private static final String ERROR_EMAIL_INVALID = "Wrong email";
private static final String ERROR_EMAIL_EXISTS = "Email used";
public EditProfileForm( String id, final ModalWindow modalWindow,final User u )
{
super( id );
this.user = u;
this.modalWindow = modalWindow;
add( new TextField<String>( EMAIL, new PropertyModel<String>( properties, EMAIL ) ).setRequired(true).setOutputMarkupId(true) );
add( new PasswordTextField( OLD_PASS, new PropertyModel<String>( properties, OLD_PASS ) ).setOutputMarkupId(true) );
add( new PasswordTextField( NEW_PASS, new PropertyModel<String>( properties, NEW_PASS ) ).setOutputMarkupId(true) );
add( new PasswordTextField( NEW_PASS_REPEAT, new PropertyModel<String>( properties, NEW_PASS_REPEAT ) ).setOutputMarkupId(true) );
final FeedbackPanel feedbackPanel = new FeedbackPanel( "feedback" );
feedbackPanel.setOutputMarkupId( true );
//feedbackPanel.setMaxMessages( 5 );
add( feedbackPanel );
AjaxSubmitLink closeBtn = new AjaxCloseCancelBtn( "close-x", this );
AjaxSubmitLink cancelBtn = new AjaxCloseCancelBtn( "cancel", this );
add( new AjaxSubmitLink( "save", this )
{
private static final long serialVersionUID = 1L;
#Override
protected void onSubmit( AjaxRequestTarget target, Form<?> form )
{
if ( !user.getCryptedPassword().equals( CypherUtil.encodeMd5( getOldPassword() ) ) )
{
error( ERROR_WRONG_PASS );
}
else if ( !getNewPassword().equals( getNewPasswordRepeat() ) )
{
error( ERROR_PASS_DIFF );
}
else if ( !validator.validateEmailFormat( getEmail() ) )
{
error( ERROR_EMAIL_INVALID );
}
else if ( validator.emailExists( getEmail() ) )
{
error( ERROR_EMAIL_EXISTS );
} else
{
//save user data
}
}
#Override
protected void onError( AjaxRequestTarget target, Form<?> form )
{
target.add( feedbackPanel );
}
} );
add( closeBtn );
add( cancelBtn );
}
/**
* #return
*/
private String getEmail()
{
return properties.getString( EMAIL );
}
/**
* #return
*/
private String getOldPassword()
{
return properties.getString( OLD_PASS );
}
/**
* #return
*/
private String getNewPassword()
{
return properties.getString( NEW_PASS );
}
/**
* #return
*/
private String getNewPasswordRepeat()
{
return properties.getString( NEW_PASS_REPEAT );
}
}
Now when I leave these forms empty, I receive nice feedback msg that there fields are required. Meanwhile, when I type wrong pass, email or whatever I got nothing, and my server log leaves msg like this:
WARNING: Component-targetted feedback message was left unrendered.
This could be because you are missing a FeedbackPanel on the page.
Message: [FeedbackMessage message = "Wrong pass", reporter = save, level = ERROR]
The form is within a WebPage which is a popup:
public class ProfilePopup extends WebPage
{
private static final long serialVersionUID = 2929269801026361184L;
public ProfilePopup(final ModalWindow modal, final User user)
{
add( new EditProfileForm("profileModifyForm", modal, user).setOutputMarkupId(true) );
}
}
and HTML, placing feedback outside the form didn't help either :

It's bad practice to perform input validations in onSubmit, because once you get there, (invalid) input has reached the Models. As you already are experiencing, onSubmit is invoked after the validation phase has ended, so the input will be considered valid, and therefore Form.onError will not be invoked.
Use a FormValidator instead (add an IFormValidator to the Form in your constructor), if you require to perform not so simple validations or validations that involve two or more components' inputs. Remember that user input will have not reached the component's Models in FormValidator.validate(), so you'll need to use Component.getConvertedInput() to get the input to be validated.
If your validations involve only one component, and operate only over its input, it might be recommendable to use an IValidator instead.
Also, notice that Wicket provides validators that perform some of the validations you'd like to perform: EqualPasswordInputValidator and EmailAddressValidator can be useful to you.
For instance:
emailField.add(EmailAddressValidator.getInstance());
form.add(new EqualPasswordInputValidator(passwordField, passwordRepeatField));
Take a look at this (somewhat outdated) wiki page for information on FormValidators: Validating related fields
