Comment 1 Peter Lam 2008-07-09 23:29:50 UTC 
this applies to the state diagram as well.
Comment 2 Peter Lam 2008-07-09 23:32:14 UTC 
the same error also occurs if CDFS an use case element to a state diagram.
Comment 3 Peter Lam 2008-07-09 23:35:11 UTC 
And cdfs a state diagram element to a use case diagram
Comment 4 Peter Lam 2008-08-09 00:45:14 UTC 
While verifying issue 138668, couldn't do cdfs anymore. It used to work and the problem only occurred on empty diagram
for cdfs. Now, the same assertion comes up even though doing cdfs on non-empty diagram. So, I call it a regression and
raise it to P2.
