Description Manfred Klug

Version: 4.2.0.200710052231NGT

The stacktrace is all I have. I'm not shure how to trigger the problem.

You will have a circular dependency in your projects.

Patch is OK. Thanks!

Comment 4 Manfred Klug

I have found the next two errors by accident. This time, you need a circular dependency between OAW projects to reproduce the problem.

I don't like to say it, but the patch for OawProject.java is still missing in the 4.2 branch.

Comment 15 Patrick Schonbach

2008-02-16 17:44:00 EST

Karsten, could you please look at it? Since loadOawResource() has changed a lot in the meantime, I am not sure, how to apply Manfred's fix that is still missing there.
