Unable to deploy GWT app in Eclipse 3.6 RC1

[mrleah]

Hi,

I have been testing WindowBuilder Pro with the Eclipse 3.6 RC1 release and I don't seem to be able to deploy my GWT app. I downloaded WindowBuilder 7.5 using the Eclipse 3.6 update site (http://download.instantiations.com/D2WB ... pdate/3.6/), and installed the compatible Eclipse GWT plugin from Google. All seems to work as expected until attempting to deploy the application using the deploy option in the Google sub menu available in the package explorer tree. There seems to be a null pointer exception generated from an instantiations package. The trace is below for reference. The deployment works fine in previous versions of eclipse using version 7.5 of WindowBuilder. I appreciate that the Helios release, and therefore WindowBuilder support, has not been finalised, but I was wondering if there might be a temporary work around until the final release is available?

Thanks in advance,
Matt.

Eclipse 3.6 introduced a bug in launch configuration management.

We have added a work around in the latest GWT Designer / WindowBuilder v7.5 build.

Thanks for the update and the rapid turnaround! I have downloaded the latest build and it has fixed the problem.

I'm glad that worked for you.
