Hi. I'm getting a null pointer exception in VE when selecting a widget
while having the Customize Layout Window open. I can't provide a
pattern, it just happens sometimes. The only thing that seems to solve
it is restarting Eclipse.
I'm using Eclipse 3.0.1, VE 1.0.2.1, EMF 2.0.2, GEF 3.0.1 and XSD 2.0.2
I don't know if someone wants to check this out, but the error log goes
like this:
!ENTRY org.eclipse.ui 4 4 Apr 10, 2005 22:29:50.75
