    jbpm5.x bpmn timer datetime format

    Sasi R Newbie

      In bpmn file, am able to use timers by defining period and delay(<timeCycle xsi:type="tFormalExpression">1d###1d</timeCycle>). However I want to decide the resurring period progrmatically outside depending on calendars and want to pass it to the workflow

       

      jBPM3.x accepts datetime variable for determining deadline but i couldnt find any corresponding doc in 5.x reg that

       

      Does jBPM5.x supports datetime varibales for defining deadline. Can you please point me to the right example?

          In the example you mentioned, a hardcoded value of 1 day is used but you can also inject a variable here, the same way you can do for service task parameters for example.

           

          So you should be able to also specify something like #{x}ms (where x is a process variable containing the amount of ms, e.g. 10), or #{y} (where y is a process variable containing the entire expression, e.g. 10h).

            Kris, Thanks for replying    

             

            I want to be able to inject procee variables(values are derived using specific business logic) in standard data time format rather than letting the bpm engine derive expiry time

             

            For example i want the task deadline to be reached at a particular input time so that timer should also expire at that time (dd-MMM-yyyy HH:mm:ss). To put it simply, its more like passing value rather than expression

              Ok, got it.  BPMN2 defines 3 types of timer expressions: timeDuration (trigger after a certain amount of time), timeCycle (trigger repeatedly) and timeDate (trigger on a specific date and time).  It seems you're looking for the last one.  Unfortunately, only the first two options are currently supported in jBPM5.

               

              I'll look at adding support for this: https://issues.jboss.org/browse/JBPM-3298

               

              As a workaround for now, I think it should be possible to use timeDuration as described earlier, but then add some action script before that that would translate the generated date and time variable back into a duration variable.
