Re: Issue with TabLayoutPanel in 2.5.0 RC1 & RC2

[Thomas Broyer]

Looks like it's a regression in 2.5.

Hopefully you have called uiBinder.createAndBindUi(this) after 
instantiating your tabPanel_? If not it won't contain any tabs.

How/when do you call your render() method? Maybe you have refactored 
something while migrating to GWT 2.5?

Re: Issue with TabLayoutPanel in 2.5.0 RC1 & RC2

[Patrick Tucker]

I may be one the wrong track here, but why are you providing  "tabPanel_"?
 
The error is because the the tab does not exist.  I did not try to run your 
code but maybe providing the TabLayoutPanel is the root of the problem.  If 
you aren't doing anything special to an Object, there is no need to provide 
the Object.
 
If you add the "-gen foldername" option to the compiler you can look at the 
compiled java code and see what the actual problem is.

Issue with TabLayoutPanel in 2.5.0 RC1 & RC2

[manoj kumar]

We have code that uses TabLayoutPanel  in UIBinders and selects the tab 
programatically. This code was working fine in 2.3, but we are getting 
Exceptions since 2.5.0 RC1 (& RC2).
Has anybody seen this before or solved this. 


Caused by: java.lang.AssertionError: Index out of bounds
at 
com.google.gwt.user.client.ui.TabLayoutPanel.checkIndex(TabLayoutPanel.java:720)
at 
com.google.gwt.user.client.ui.TabLayoutPanel.selectTab(TabLayoutPanel.java:597)
at 
com.google.gwt.user.client.ui.TabLayoutPanel.selectTab(TabLayoutPanel.java:587)

The following is the code.
UIBinder.ui.xml:


Tab1 
Tab1 Contents


Tab2 
Tab2 Contents


Following is the java code in the widget.

public class TestPage {
 @UiField (provided = true)
protected TabLayoutPanel tabPanel_;

   public TestPage() {

tabPanel_ = new TabLayoutPanel();
}

@Override
public Widget render(Map parameters) {
tabPanel_.selectTab(0);

  }

}
