AW: [mdt-bpmn2.dev] SubProcess as InteractionNode
|
Hi Anne,
welcome!
About your question: SubProcess (embedded subprocess) is indeed not a InteractionNode and cannot be connected with MessageFlow. The picture on page 44 could be either interpreted as collapsed CallActivity or collapsed embedded sub process (SubProcess). I would assume that the authors had in mind the first one. For me it does not make sense to have incoming or outgoing message flow from an embedded subprocess, as the subprocess does not send or receive anything. Anyway, the depiction could be valid, if you have incoming/outgoing message flow from/to one or more elements that are contained in the SubProcess - and the subprocess is visually collapsed. But in this case the semantic model still uses the contained element (e.g. event or send/receive task) as source/target), but the BPMNEdge (in DI) would point to the collapsed SubProcess.
Regards,
Reiner.

Betreff: [mdt-bpmn2.dev] SubProcess as InteractionNode
Dear Community,
recently I started to model BPMN 2.0 models in Eclipse with the MDT
BPMN2.0 Modeler. Importing my own models I realized, that a MessageFlow
between SubProcesses causes a problem (IllegalValueException). Looking
at the cause it seems to be a ClassCastException:
org.eclipse.bpmn2.impl.SubProcessImpl cannot be cast to
org.eclipse.bpmn2.InteractionNode.
If I understand the problem correctly, the message flow in MDT BPMN2.0
Modeler is not allowed between subprocesses, but from the published BPMN
2.0 Beta 2 (dtc/2010-06-04) it is possible for all kind of activities:
depicted in the table 7.4 on page 44 and documented on page 124. For
this reason the meta-model on page 123 would also be erroneous (it
states only the Task as InteractionNode).
Regards,
Anne
