[great-users] Problem when using great

[Zonghua Gu]

I am a new user of GReaT. I created a new transformation file with a
trivial transformation, but I got an error:
Exception: association resolves to invalid object type: ThreadConnection

If I remove ThreadConnection in the meta-model and redo it, it
complains about another XXXConnection; if I remove that one, it
complains about the next one, etc.

I have put the related files at

http://www.cs.virginia.edu/~zg4v/GreatProblem.zip

Thanks.
