[jboss-user] [JBoss jBPM] - Swimland reassignment Example
I recently figured out how to reassign swimlanes for a processInstance and thought an
example might help others
Note: the assignments are currently hardcoded but a more production capable version of
this Action could be designed that retrieves a processInstance varaible, possibly a
hashMap and iterates over the key value pairs assigning the value to swimlane (key).
Any thoughts on the code? I had to do the Session.save(swimlane) in order to get it to
work. Anyone see any problems with this?
