GWT Designer apparently does not support GXT 3.0.1

[GoogleCodeExporter]

Environment:
- Eclipse Juno SR 1
- GWT 
Designer    2.6.0.r42x201206111253  com.google.gdt.eclipse.designer.feature.feature.
group   Google, Inc.
- OpenShift application (JBoss AS 7.1 runtime) with following Maven 
dependencies:
  + com.google.gwt : gwt-dev : 2.5.0
  + com.google.gwt : gwt-user : 2.5.0
  + com.google.gwt : gwt-servlet : 2.5.0
  + com.sencha.gxt : gxt-release : 3.0.1 : pom

What steps will reproduce the problem?
1. Create new "GWT Module". 
2. Add "<inherits name="com.sencha.gxt.ui.GXT"/>" to <module>.gwt.xml
3. Open <module>.java with WindowBuilder Editor.
5. GXT UI elements are not available, nor it is the "Binding" tab. 
6. Add manually some GXT ui element in <module>.java
7. Re-open <module>.java with WindowBuilder Editor.
8. Editor shows an error message: java.lang.NoClassDefFoundError: 
com.sencha.gxt.widget.core.client.Component

What is the expected output? What do you see instead?
- Expected output is to be able to visually add and manage GXT UI elements from 
the WindowBuilder toolbar.

I have finally found that this is not an issue. GXT 3.0.1 is not compatible 
with GWT Designer. Check this out:

Maybe Sencha will release it in the future (CEO spoke about "upcoming support 
for GXT 3 in GWT Designer" at Google I/O 2012), but in the meatime I have 
tested GXT 3.0.1 LGPL and I agree with whom in the forum above say that WYSIWYG 
is not so useful. Manual coding is much better with GXT3, considering that 
GWT-GXT testing (either run or debug) from Eclipse is straightforward.
