Comment 6 Lukas Hasik 2005-03-15 15:22:23 UTC 
happend again with build 200503150955+me050315_19q-builds)
What I did:
1, installed NB, and run with fresh userdir - u1, exit
2, installed mobility pack and run again with userdir u1
3, created j2me project
4, created j2me library project
5, NPE when creating java class in unexisting package in class project

I hope that it helps
Comment 7 Jan Becicka 2005-03-16 18:23:12 UTC 
Something strange is happening during instantiating of Java Class. It looks like
JavaDataObject is created, but it is immediately invalidated and replaced by
J2MEDataObject. RepositoryUpdater gets valid JavaDataObject and passes it to
ASTProvider. In the meantime JavaDataObject became invalid and is replaced by
J2MEDataObject. Insofar that ASTProvider.getASTree receives invalid DataObject
and returns null.

I have a patch, which is rather workaround than fix.
Real fix should be IMHO done in j2me module, which is responsible for this
hanky-panky.

Comment 9 Adam Sotona 2005-03-17 12:31:26 UTC 
There is currently no way how to change it in j2me module. All java files inside
J2ME project must be recognized as J2MEDataObject instead of JavaDataObject.

This is one case when it fails. Create from template on JavaDataObject creates
directly a new instance of JavaDataObject without asking data loaders. It means
that any new java file created inside J2ME project must be invalidated and
recognized back as J2MEDataObject.
