[jboss-user] [JBoss jBPM] - Swimland reassignment Example

[jmjava]

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?
