Did you find a fix to this.
Am migrating from 3.3.0 to 3.2.6.SP1 and getting the same error.

So my final (JBPM 3) solution for this requirement is as follows.
An actionhandler in the subprocess which propagates the event to the
superprocess.
public void execute(ExecutionContext executionContext) throws Exception {

A bit more digging and I think I'm closer to the problem. It seems the problem
is to do with setting a timer on a superstate. I reduced my superstate
definition down to one state within the superstate and still the problem occurs.
When I replace the superstate with
I have rather belatedly come back to this one, having not made the switch to
jBPM4 - I find the jbpm-console more friendly for trying things out thanks to
the ability to signal tokens.
I still don't see how this works in JBPM3, may be it works in 4. What I'm
trying to achieve is similar to

Ronald,
Maybe I've missed something but if the event is propagated to the super-process
level then I need to write an actionhandler/eventlistener to direct it at the
node in question or is it visible to all nodes in the process?
Another question - can events be filtered by source node?
View
Just thinking through the behaviour I'm looking for I realise that once the
event is propagated up it needs to be detected / signal a particular node in
the super-process. Is there an obvious way of doing this in jBPM?
View the original post :
Hmm, having looked at the code and a few entries in this forum relating to
visibility of parent process from the sub-process this appears to be a current
limitation in 3.3
Before I raise a feature request, a question; is this also an issue in 4.0?
View the original post :
Are events propagated from sub-processes to parent processes?
I have a sub-process where I want to detect certain events at the parent
process level without interrupting the flow of the sub-process. I've tested
this with a simple sub-process within a process state and the sub-process
events

This is a cross-post from the jBPM design forum. I thought this would be of

Yes, the security still needs to be bought in line with the RFCs at a minimum.
Interesting idea about the hash ids.

Unless I'm missing something the logs aren't recorded for all updates or
