GWT Designer Internal Error in Design mode (Eclipse Juno)

[k2s]

anybody has solution for problem described here http://code.google.com/p/google-web-toolkit/issues/detail?id=7492 ?

Instead of design form of UI editor I get this message:

 

Internal Error

encountered unexpected internal error.
 

This could be caused by a bug or by a misconfiguration issue, conflict, partial update, etc.

java.lang.Error: fullImage.getBounds()=Rectangle {0, 0, 1, 1} cropBounds=Rectangle {10, 10, 450, 300}


Stack trace:

I had this problem after trying to resize a layout panel and even pulling the source files down from backup didn't resolve the issue.   GWT plugin must be saving the size information somewhere other than the XML file.

I resolved it by cleaning, then deleting the project and importing it again as existing source.

Once I did all that I was able to view the UIBinder file in the WindowBuilder design tab.
