Apologies in advance if this is not the appropriate forum for posting a question:

I'm new to jBPM (just downloaded 5.1.0.final a few days ago) and have run into a small frustration.  Whenever I try to insert a Component (e.g. a Script Task) after a Diverging Gateway, the Java code that defines the associated Diverging Gateway Constraint disappears.   I've tried a number of different combinations, e.g. inserting the Component and then moving the Sequence Flow arrow, deleting the arrow and then inserting the new Component, but nothing seems to work.   There doesn't seem to be any way of inserting a new Component without losing the Java code associated with the Constraint in question.  Any ideas anybody?  Thanks in advance, and again, if this is not the appropriate place for posting questions, please just give a pointer and I'll be glad to comply.
