Hi,
Thanks for the suggestion about putting a PN director inside the
composite, I was not sure if I was supposed to do that or not.
Under Ptolemy II 5.0-beta, when I have a PN inside PN, the
model runs fine.
Under Ptolemy II 4.0.1, when I have PN inside PN, the model
hangs.
I'll see if I can create a test case for this.

Thanks for the fast response.
Did you try it after adding a PN director into the composite actor?
There isn't one in the attachment, that's just my "case 1"...
I'm running on Win XP with JDK 1.4.2_06.
Regards
Erwin
