I tried to import one of my widgets in another ui.xml file.
In eclipse no errors are shown but in (maven) development mode it says:
[ERROR] Package not found: de.s.pp.client.application.projectdetail.overview.subview
The widget that imports:
<ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder'

Did you forgot to add jar file, to use the de.s.pp.client.application.projectdetail.overview.subview
The problem was that the absolute path of the file was to long

I'm trying to use GWTP in my GWT 2.7 application but the UI in my uibinder is not displaying. My app compiles and runs in Super dev mode without any errors, but I get a blank screen. I expected the HTML in the LayoutView.ui.xml to show in the browser. I'm sure I'm missing something really basic. Any help would be great.
The following is included in my .gwt.xml file
<inherits name='com.google.gwt.inject.Inject' />
<!-- Other module inherits -->
<inherits name="com.google.gwt.uibinder.UiBinder" />

I generated the Layout presenter using the GWTP plugin.
I tried to follow the sample tutorials at
http://dev.arcbees.com/gwtp/sampletutorial/
and
https://code.google.com/p/gwt-platform/wiki/GettingStarted#Getting_the_sample_applications
but some of it seems to be deprecated
You don't have a presenter with a ProxyPlace and the annotation #NameToken on it. To get your code working quickly, you can change LayoutPresenter.MyProxy to:
#ProxyStandard
#NameToken(NameTokens.LAYOUT)
interface MyProxy extends ProxyPlace<LayoutPresenter> {}
Also the Google Code documentation is actually outdated by a lot. There are warnings all over the place, so I thought this was obvious.
The documentation on https://dev.arcbees.com/gwtp/sampletutorial/ is recent enough to help you develop a working application. You can also have a look at GWTP's Basic Sample for more examples: https://github.com/ArcBees/GWTP-Samples/tree/master/gwtp-samples/gwtp-sample-basic
I am trying to find my way around with the Google Web Toolkit. Right now I am trying to get a Canvas widget up and running.
But I am getting this error and do not understand why:

My code looks like this:

I bet the answer will be pretty easy but I do not know why I get this error message and why the code does not compile.
Edit:
So after trying the advice below it works. Here comes the edited code which draws a black triangle.

panel.add(tCanvas);
RootPanel.get().add(this);
}
}
You cannot create a Canvas with the UI:Binder, because there is no zero-arg constructor, nor a #UIConstructor.
I would suggst to create a warpper (A simplePanel) and within your Wrapper-Code, you can create a Canvas, by calling Canvas.createIfSupported():
The canvas itself is prvided.
#UiField(provided = true)
Canvas canvas;
Before you call binder.createAndBindUi(this); you will have to create the Canvas:
canvas = Canvas.createIfSupported()
I have no simple example, but maybe, this link is helpful:
https://code.google.com/p/gwtgae2011/source/browse/src/main/java/com/googlecode/gwtgae2011/client/main/SketchView.java?r=8e7169e7fbb411f320f99f77dcdb27efa27b727a
You also could use a CanvasElement, like described in this question:
GWT uibinder CanvasElement wont resize when deployed
I want to learn the utility of lazypanel of GWT. I want to use it using Uibinder. I have written the code as below. I want to use the lazy panel for tablayoutpanel.

According to this you have this error if you do not have an #UiField annotation for the LazyPanel. So I would try the following:
For the UiBinder XML file:
<!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent">
<ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder"
xmlns:g="urn:import:com.google.gwt.user.client.ui"
xmlns:d="urn:import:com.google.gwt.dom.client"
xmlns:lazy="urn:import:abc.client">
<g:HTMLPanel>
<lazy:Lazy1 ui:field="myLazy1"/>
</g:HTMLPanel>
</ui:UiBinder>
For your AbcUi.java file:
package abc.client;
import com.google.gwt.core.client.GWT;
import com.google.gwt.uibinder.client.UiBinder;
import com.google.gwt.user.client.ui.Composite;
import com.google.gwt.user.client.ui.HTMLPanel;
import com.google.gwt.user.client.ui.LazyPanel;
public class AbcUI extends Composite {
interface abcUIUiBinder extends UiBinder<HTMLPanel, AbcUI> {}
private static abcUIUiBinder uiBinder = GWT.create(abcUIUiBinder.class);
#UiField
Lazy1 myLazy1;
public AbcUI() {
initWidget(uiBinder.createAndBindUi(this));
}
}
Using GWT 2.5.0,
I would like to use Client side validation and Editors. I encounter the following error when trying to pass the ConstraintViolation java.util.Set to the EditorDriver as follows.
Validator a = Validation.buildDefaultValidatorFactory().getValidator();
Set<ConstraintViolation<Person>> b = a.validate(person);
editorDriver.setConstraintViolations(b);
The method setConstraintViolations(Iterable<ConstraintViolation<?>>) in the type EditorDriver<Person> is not applicable for the arguments (Set<ConstraintViolation<Person>>)
The only somewhat relevant post I could find was Issue 6270!
Below is an Example which brings up a PopUpDialog with a Person Editor that allows you to specify a name and validate it against your annotations. Commenting out the personDriver.setConstraintViolations(violations); line in the PersonEditorDialog will allow you to run the example.
I don't have enough reputation points to post the image of the example.

As discussed in the comments, the following cast was determined to be a valid workaround.
Set<?> test = violations;
editorDriver.setConstraintViolations((Set<ConstraintViolation<?>>) test);
This is what I do over and over again :
List<ConstraintViolation<?>> adaptedViolations = new ArrayList<ConstraintViolation<?>>();
for (ConstraintViolation<Person> violation : violations) {
adaptedViolations.add(violation);
}
editorDriver.setConstraintViolations(adaptedViolations);
The driver has a wild card generic type defined and you can not pass in the typed constraint violations.
I am a newbie trying to use a MenuBar to swap the displayed panel in a DeckPanel.
I have 2 classes and 2 associated uibinder XML files:
ApplicationUi.java
ApplicationUi.ui.xml
ApplicationMenu.java
ApplicationMenu.ui.xml
In ApplicationUi.java and the UI XML, the root is bound to a DockLayoutPanel. The ApplicationMenu is meant to be in the North section of the DockLayoutPanel. The MenuBar options will affect the DeckPanel in the Center section.
In ApplicationMenu, how can I get a reference to the DeckPanel so I can call showWidget() to swap the displayed panel?
Also, since I'm a newb, any suggestions or reviews of this code are welcome. I've done the best I can on Google, but alot of what I'm looking for doesn't seem to be out there.
(This is a followup to Replace GWT DockLayoutPanel Contents).

One way you could do this would be to use an EventBus. Create an event type and have your ApplicationMenu fire an event of that type when a menu item gets clicked. The ApplicationUi object can subscribe to that event and respond to it by updating the contents of the DeckPanel. This avoids the menu object needing to know about the DeckPanel at all.
