the seam nightly builds are still 'stuck' on 06.14.2007 as the last build - any
chance the nightly builds will resume being posted regularly?
Thanks,
Brad

Of course, and indeed I'm not assuming an actor only has a single task
assigned. So, for example, when a human actor logs into some website then
indeed a list of tasks will often be very appropriate.
However, when a
I think the code for auto-starting tasks is an area which is extremely use-case
specific (assuming the actor has only one task assigned is a *big* one) so
should be implemented on a case-by-case basis.

Actually, I think one day I also might want to start a task as soon as one

Ok, now that Gavin gave a nice combination of @StartTask and pages.xml, I
wonder if something similar could be done using the value returned by
@CreateProcess, somehow also forcing @StartTask to be triggered?
Now, how to explain this... In the Todo example we've got:

Another EJB (yes a seam component) has created the process instance - then,
based on certain business conditions, the process gets signaled through the
tasks until we arrive at this particular state (node). On entry into the
state, this ActionHandler fires (I posted the XML for this state node
What exactly is driving jBPM here? What causes the event to fire?
