[werkflow-user] blog example not firing publish/reject process

Hi,
I'm trying werkflow.
I've just read the article 'The application of Petri Nets to Workflow 
Management' and starting to play with werkflow (beta-6) for an 
application using JavaGroups as the messaging transport.

As I've some problems with the blog demo (I'm running it from IntelliJ) 
and seen on the mailing list archives both the old messages and the cvs 
commit.

The problem is that the reject and publish processes are not invoked.

 From stepping in the debugger it seems to me like the message is asked 
for acceptance but never consumed (??).

Anyone has the same problem?

Thank you very much
Federico
