Subject: [mylyn-dev] Problem in running the latest dev source for Eclipse


After I updated the source code from CVS this afternoon, I caught a problem
when opening an existing Trac ticket -- an error message poped up saying
that "Unable to create this part due to an internal error. Reason for the
failure: Argument cannon be null".

I first thought it was from some of the changes I made, but my debugging
tracked the error at line 897 of AbstractRepositoryTaskEditor:
where the passed argument val was null and CCombo threw an exception for
that. This happened when an attribute ( e.g. version) has an empty option
value, but the List<String> options in RepositoryTaskAttribute contains a
null rather than "".

The problem didn't occur when I run eclipse with a clean workspace, but the
next time running eclipse without clearing the workspace, bang. So it looks
to me it's from caching the repository task data, but I didn't trace it

Maybe someone knows what happened?
