Hi Suzy,
each expression (like 'sequence', 'participant' or 'concurrence') has
a unique flow expression id. The most unique part in it is the
'workflowInstanceId'.
In some cases, parts of a workflow instance are repeated or iterated,
the engine cannot reuse the exact same FlowExpressionId, it has to
differentiate this "subflow", so it appends a ".x" to the workflow
instance id. With this simple technique, you still know wich is the
main flow.
When you have an instance of FlowExpressionId, say 'fei' you can do :
pureWfid = fei.getParentWorkflowInstanceId();
it will return the wfid without any ".x", just the workflow instance
id of the 'parent' workflow.
Best regards,
