testing wicket pages - wicket

I am writing tests for wicket pages. I have three dropdowns on my page. Depending upon the values selected from the dropdowns the panel gets rendered(the panel contains a data table).
How do I change the values of the dropdowns from the wicket test so that I can test the rendered panel for different combination of values selected?

#Test
public void testPanel() {
WicketTester tester = new WicketTester(new JavaWhatApplication()) ;
DropDownChoice<Type> typeDropDown =
(DropDownChoice<Type>)tester.getComponentFromLastRenderedPage("categoryForm:types");
assertEquals(3, typeDropDown.getChoices().size());
FormTester formTester = tester.newFormTester("categoryForm",false);
formTester.select("types", 1); // 1 is index
tester.executeAjaxEvent("categoryForm:types", "onchange");
}

Wicket form missing data on submit

I have a ModalWindow which has a form, which has a TabbedPanel, which has two AbstractTabs which, on which there is a DataTable on each of them, with input elements.
So: ModalWindow > Form > TabbedPanel --> Tab1 (Panel) > DataTable (there are two tabs)
Within the ModalWindow, I added to the form 3 buttons, like the following:
// save button
final GbAjaxButton save = new GbAjaxButton("save") {
private static final long serialVersionUID = 1L;
#Override
public void onSubmit(final AjaxRequestTarget target, final Form<?> form) {
System.out.println("Saving something... ");
}
};
I can see the data being sent via POST to the backend, but I can't seem to be able to access any of the fields in the DataTables.
Some parts for the code are:
tabA = new AbstractTab("Tab Name") {
public Panel getPanel() {
return new SomeNewPanel(panelId,<somedata>); // <-- this has the DataTable with inputs
}
}
Form form = new Form("formNameInHtml");
form.add(new TabbedPanel("htmlName", tabs);
I would really appreciate some insight on this problem.
Thanks.
From ModalWindow javadoc, "If you want to use form in modal window component make sure that you put the modal window itself in another form (nesting forms is legal in Wicket) and that the form on modal window is submitted before the window get closed."
Wicket automatically adds a form outside the modal window, so if you want to use a second form inside you should override org.apache.wicket.markup.html.form.Form#isRootForm() and have it return true.

What would be a good way of filtering a GWT CellList using multiple CheckBoxes?

Working in Google Web Toolkit (GWT) I am using a CellList to render the details of a list of Tariffs (using a CompositeCell to show a CheckBoxCell next to a custom cell of my own).
I want to filter the list by tariff length (12, 18, 24, 36 months etc). I would like to render a checkbox for each tariff length at the top of the list, and update the dataProvider as necessary when users uncheck and recheck a box.
I do not know in advance the set of tariff lengths, they will be extracted from the result set when the page is rendered. There could just be two (requiring two checkboxes), but possibly there could be 10 (requiring 10 checkboxes) - I only want to render a checkbox for each as needed.
So somehow I need to associate an int value with each checkbox, and then pass that int to a function that updates the list by removing all tariffs that match. I'm just not sure how to add the handler for the checkboxes and how to get the value for that particular box.
This is what I'm thinking:
// panel to hold boxes
private Panel contractLengthPanel = new HorizontalPanel();
textPanel2.add(contractLengthPanel);
// create a set of the terms, by looping the result set
Set<String> contractTerms = new HashSet<String>();
for(ElecTariff tariff : tariffs)
{
contractTerms.add(Integer.toString(tariff.getContractLength()));
}
// loop that set, creating a CheckBox for each value
for(String term : contractTerms)
{
CheckBox box = new CheckBox(term + " Months");
// set all boxes with the same name, and a unique id
box.getElement().setAttribute("name", "termBoxes");
box.getElement().setAttribute("id", "termBox" + term);
contractLengthPanel.add(box);
}
Now I'm not sure if I'm along the right lines here, but now I have each box as part of the same group (they have the same name) I would like to use that to add a handler that is called when a box is checked or unchecked, passing the box id (which contains the tariff length) to that function.
I hope this wasn't too confusingly written. Help appreciated.
There really is nothing like a "group of checkboxes" in HTML, and neither there is in GWT. There are kind of "groups of radiobuttons" though, but it's only about having their checked state mutually exclusive, it doesn't change anything to the way you work with them from code.
You have to listen to changes on each and every checkbox.
What you can do though is to use the same event handler for all your checkboxes; something like:
ValueChangeHandler<Boolean> handler = new ValueChangeHandler<Boolean>() {
#Override
public void onValueChange(ValueChangeEvent<Boolean> event) {
CheckBox box = (CheckBox) event.getSource();
String id = box.getFormValue();
boolean checked = box.getValue();
…
}
};
(note: I used getFormValue() rather than getElement().getId(); I believe it's a better choice: it's specifically made to associate a value with the checkbox)

GWT SimplePager LastButton issue

I am facing problem with lastButton of SimplePager.
I have 3 pages in celltable, Page size=11 (1 empty record + 10 records(with value)), Total record=26.
I used CustomerPager by extending SimplePager.
In 1st attempt 1+10 records display in celltable : Next & Last page button is enabled (First & Prev button disabled) which is correct.
But LastPage button not working... :( Dont know whats the issue... (event not fires)
Strange behavior:
#1 Last page button is working only when I visit to last page(3 page in my case).
#2 Assume I am on 1st page n I moved to 2nd page(Total 3 pages in celltable). that time all buttons are enabled which is correct.
In this case Last button is working but behave like Next Button
My GWT application integrated into one of our product so cant debug it from client side.
May be index value is improper in setPage(int index) method from AbstractPager
Code flow is as follows for Last button
//From SimplePager
lastPage.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event) {
lastPage();
}
});
#Override
public void lastPage() {
super.lastPage();
}
// From AbstractPager
/**
* Go to the last page.
*/
protected void lastPage() {
setPage(getPageCount() - 1);
}
protected void setPage(int index) {
if (display != null && (!isRangeLimited || !display.isRowCountExact() || hasPage(index))) {
// We don't use the local version of setPageStart because it would
// constrain the index, but the user probably wants to use absolute page
// indexes.
int pageSize = getPageSize();
display.setVisibleRange(pageSize * index, pageSize);
}
}
or may be some conditions false from above code(from setPage())
actual record = 26 and 3 Empty record (1st Empty record/page)
May b problem with dataSize :|
How I can check number of pages based on the data size?
?
How can I solve this problem?
edit: I found out that the default constructor of the pager doesn't give you a "last" button, but a "fast forward 1000 lines" button instead (horrible, right?) .
call the following constructor like so, and see your problem solved:
SimplePager.Resources resources = GWT.create(SimplePager.Resources.class);
SimplePager simplePager = new SimplePager(TextLocation.CENTER, resources , false, 1000, true);
the first "false" flag turns off the "fastforward button" and the last "true" flag turns on the "last" button.
also the last button will work only if the pager knows the total amount of records you have.
you can call the table's setRowCount function to update the total like so:
int totalRecordsSize = 26; //the total amount of records you have
boolean isTotalExact = true; //is it an estimate or an exact match
table.setRowCount(totalRecordsSize , isTotalExact); //sets the table's total and updates the pager (assuming you called pager.setDisplay(table) before)
if you are working with an attached DataProvider, than all it's updateRowCount method instead (same usage).
Without seeing more of your code, this is a hard question to answer as there could be multiple places where things are going wrong.
I would make sure you call setDisplay(...) on your SimplePager so it has the data it needs calculate its ranges.
If you can't run in devmode, I recommend setting up some GWT logging in the browser (write the logs to a popup panel or something, see this discussion for an example).
I think the problem is related with condition in the setPage(). Try putting SOP before if condition or debug the code
Only added cellTable.setRowCount(int size, boolean isExact) in OnRange change method AsyncDataProvider. My problem is solved :)
protected void onRangeChanged(HasData<RecordVO> display) {
//----- Some code --------
cellTable.setRowCount(searchRecordCount, false);
//----- Some code --------
}

make the gwt celltable row selected

I have a cell Table in GWT with columns , there are 3 rows in each column, I want the first row to get selected by default when the application starts
some thing like this
mycelltable.setselectedrow(index);
is it possible ?
Thanks
her is the code
display.getShortListedCVsBasedOnJob().getResumeDescriptionColumn().setFieldUpdater(
new FieldUpdater<CandidateSummary, String>() {
public void update(int index, CandidateSummary object,
String value) {
fetchResume(cvSelected, shortListedFlag);
}
});
This fetchResume() method calls but only when i select cell of this column , I want to call this fetchResume() method as my application starts, i.e i want to make the 1st cell of the column to be selected byDefault.
Selection is handled by a SelectionModel, based on objects (not indices); so you have to select the first object from your data in the SelectionModel used by the CellTable (have a look at the Using a key provider to track objects as they change sample code in the Celltable javadoc for an example (last sample before nested classes summary).
This could work?
setSelected(Element elem, boolean selected)
see GWT Documentation
CellTable Google Web Toolkit
Hmm I dont see what´s the Celltable is there. I would set the initial Value like this:
int INITAL_SET_ROW = 0;
TableRowElement initalSetElement = yourCellTable.getRowElement(INITAL_SET_ROW);
yourCellTable.setSelected(initialSetElement, true);
You can try to implement it in you´re main Method. Haven´t tested it tho, hope it helps.
Simply;
List<RowType> source = new LinkedList<RowType>();
//put some data to this list
//populate the table
table.setRowCount(source.size(), true);
table.setRowData(0, source);
//for example, you can select the first row
RowType firstRow = source.get(0);
selectionModel.setSelected(firstRow, true);

How can I make GWT list box editable a part from selection

As per my requirement I have written a custom panel which will display three ListBoxes to enable user to select date from this custom list boxes.These three list boxes are responsible for showing month,day,year value. Now I would like to make my three list boxes are editable and at the same time selectable. I mean I would like to provide a user preferences that date can editable and at the same time selectable. How can I do this in GWT. Here I am using GWT2.0. Any one please give an idea.
A browser does not provide such a control. Neither does GWT. You will need to code your own. EXT-GWT(not free) ComboBox has this functionality. http://www.extjs.com/examples/
So does Smart GWT (also not free) http://www.smartclient.com/smartgwt/showcase/#styled_combobox_category
If you were to roll your own, you would start with a Composite which has a TextBox and a VerticalPanel that is shown when a TextBox (or part of it) is clicked. Your panel would contain the clickable items.
You could work that out using a suggestBox instead of the list box. But user would have to start typing to display the list.
You can use absolute panel to achive the same ...
Below is the code snippet.
Hide the selectbox using textbox adjust the width and location of textbox so that it should cover dropdown list...
final AbsolutePanel absolute_panel_edit_list = new AbsolutePanel();
final TextBox onhold_textbox = new TextBox();
final ListBox onhold = new ListBox();
for (int onholdcount = 0; onholdcount < onHoldTypes.length; onholdcount++)
{
onhold.addItem(onHoldTypes[onholdcount]);
}
onhold.addKeyPressHandler(new KeyPressHandler()
{
#Override
public void onKeyPress(KeyPressEvent event)
{
onhold_textbox.setStyleName("onhold_textbox");
absolute_panel_edit_list.add(onhold,0,8);
absolute_panel_edit_list.add(onhold_textbox,1,10);
absolute_panel_edit_list.setSize("142px", "35px");
flex_row4.removeCell(4, 9);
flex_row4.setWidget(4, 9, absolute_panel_edit_list);
onhold_textbox.addMouseOutHandler(new MouseOutHandler()
{
#Override
public void onMouseOut(MouseOutEvent event)
{
String customized_time = onhold_textbox.getText();
int no_of_elements = onhold.getItemCount();
onhold.addItem(customized_time);
onhold.setSelectedIndex(no_of_elements);
flex_row4.removeCell(4, 9);
flex_row4.setWidget(4, 9, onhold);
flex_row4.setWidget(4, 11, completed_togglebutton);
flex_row4.setWidget(4, 13, completed_label);
}
});
}
});
