I'm missing some configuration?

Thank you.

[Eric Clayberg]

Give this a try using the latest 8.1 build...

http://code.google.com/javadevtools/dow ... -beta.html

[domfe]

I've upgraded. But the problem still persists.
I get the error when I open/close the Layout property or when I click on one sub-property of Layout.
No errors when I pass the mouse over.

thank you.

[Eric Clayberg]

We are unable to reproduce this.

It would be helpful to see a test case that will trigger this as well as the complete stack trace you are now seeing (best to submit this via the Contact Support button).

[domfe]

Hi.
I'm using the latest test build and the problem still persists.
I've got the error with RowLayout also.

[Eric Clayberg]

Still looking for a test case...

[domfe]

Code: Select all

    <Shell xmlns="http://www.eclipse.org/xwt/presentation" xmlns:x="http://www.eclipse.org/xwt" x:Class="test.Example2" text="XWT Application">
       <Shell.layout>
          <RowLayout/>
       </Shell.layout>
       <Shell.layout>
       </Shell.layout>
       <Label text="New Label">
       </Label>
    </Shell>


Click on Shell widget.
Open/Close Layout property.
The error appear in the "Error Log" tab of Eclipse.

Hope this helps.

We are unable to reproduce this.

BTW, your test case appears top be bad...there are two "Shell.layout" sections when there should only be one.

[domfe]

Hi Eric,
sorry for the test case.

Code: Select all

<Shell xmlns="http://www.eclipse.org/xwt/presentation" xmlns:x="http://www.eclipse.org/xwt" x:Class="test.Example1" text="XWT Application">
   <Shell.layout>
      <RowLayout/>
   </Shell.layout>
   <Button text="Double click me!"/>
</Shell>


I've done a fresh install of Eclipse and the problem still persists.
Here the steps I've taken.

1. Download Eclipse IDE for Java Developer Windows 32 bit (version 3.6.1)
eclipse-java-helios-SR1-win32.zip
2. Download e4 Project version 0.11M3
eclipse-e4-repo-incubation-0.11M3.zip
3. Install (unzip eclipse)
4. Launch eclipse, install new software, install eclipse-e4-repo-incubation-0.11M3.zip (check all)
5. Restart
6. Add WBP beta repository and check all
7. Restart
8. Add WBP latest repository and check SWT Designer XWT Support
9. Restart
10. New project - SWT/Jface Java project - name mytest
11. New XWT Application - package test - name Example1
12. In the design view click on Shell widget and open the Layout property, error appears

Hope that helps.

I still don't know. Your example works fine on on our end.

Give this a try using the latest build and see if it makes any difference...

http://code.google.com/javadevtools/dow ... -beta.html

[domfe]

The latest build seems to work. Error disappeared.

Thank Eric!

[Eric Clayberg]

That is good news.
