BPMN11 — Where are tokens queued?

  • Key: BPMN11-63
  • Legacy Issue Number: 10341
  • Status: closed  
  • Source: NIST ( Mr. Conrad Bock)
  • Summary:

    In the following process, assume mulitple tokens are being fed to A
    from upstream (<X> = exclusive OR split, <+> = AND Join):


    ----> A – <X> <+> --> B


    I assume two executions of A are required for each execution of B (if
    not, correct the parts of the spec that imply this).

    Where are tokens queued up that don't have a matching one to get
    through the AND join? BPMN should indicate where the queuing happens,
    because it affects execution. If queuing is at the the exclusive-OR
    split, then conditions could change over time and the guard could
    direct the token to a different path after the token as been queued a
    while. Or token could queue at the join, and only be tested by the
    guards once.
