TimerStartEvents of EventSubprocesses can't evaluate variable timer expressions

XMLWordPrintable

    • Type: Bug Report
    • Resolution: Unresolved
    • Priority: L3 - Default
    • None
    • Affects Version/s: 7.10.0, 7.11.0, 7.12.0, 7.13.0
    • Component/s: engine
    • None

      Scenario:

      • Deploy the attached process
        • Process with a TimerStartEvent on a EventSubprocess
        • TimerStartEvent uses an expression for the timer duration, like ${duration}
      • Start a process instance and pass duration="PT1M" variable in Cockpit

      Observed behavior:
      An exception is thrown:

      Expected behavior:
      A process instance is started successfully.

      Hints:
      We already fixed similar scenarios in CAM-9303.

      The difference here is that the process instance is started by Submitting a Form (SubmitStartFormCmd).
      CAM-9303 was more or less an easy-pick but it does seem the case here as the variables are set at different point (DefaultFormHandler#submitFormVariables()) than the initialization of the timer declarations (ExecutionEntity#startWithFormProperties())
