TimerStartEvents of EventSubprocesses can't evaluate variable timer expressions

XMLWordPrintable

      Scenario

      • Process with a TimerStartEvent on a EventSubprocess
      • TimerStartEvent uses expression for the timer duration, like ${duration}
      • process instance is started with timer epxression variable (duration = "PT1S")
      • Process instance starting fails
      • The following exception is printed
      org.camunda.bpm.engine.ProcessEngineException: Unknown property used in expression: ${duration}. Cause: Cannot resolve identifier 'duration'

      Expected

      No exception is thrown, timer can be evaluated and timer start event can occur.

      Problem

      In the PvmExecutionImpl the timer declarations are initialized before the variables are set.
