[bpmn-user] Stackoverflow error/ClassCastException with Galileo and BPMN

["Pfau, Matthias" <map@xxxxxxxxxxx>]

Hello Antoine,
I just started using the BPMN Modeler and I get an ClassCastException followed by a Stackoverflow error (see attachment) when I try to connect two pools or a task and a pool.

Kind Regards
Matthias

java.lang.ClassCastException: org.eclipse.stp.bpmn.impl.PoolImpl cannot be cast to org.eclipse.stp.bpmn.Activity
