Comment 2 Sergey Petrov 2009-01-13 13:43:40 UTC 
can you attach your project or may be any project with smilar diagram with the same problem?
Comment 3 Sergey Petrov 2009-01-13 14:03:31 UTC 
I'll add null check in this place, but need to know root cause.
Comment 4 Sergey Petrov 2009-01-13 14:16:35 UTC 
null check is integrated into team repository, approx in two days it will be in daily build. feel free to try if this
will allow to open your diagram.
Comment 5 Sergey Petrov 2009-01-13 14:21:51 UTC 
or wait for m2 build a bit if don't want to use daily.
Comment 6 Quality Engineering 2009-01-16 07:26:58 UTC 
Integrated into 'main-golden', will be available in build *200901160201* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
