Support for start timer event

chris_joelly — Sun, 06 Mar 2011 16:53:56 GMT

Hello,is the BPMN 2 element "start timer element" supported by Activiti 5.3? As there is no "Activiti palette" anymore in the modeller and no elementin the latest version of the eclipse designer and the documentation doesnot list this element it seems that it is not possible to trigger processesusin

No, it is not as you deduced correctly.

Correct. However, Maciek is working on it, but nothing has been planned as he is doing it all in his free time.

just my thinking: would it be possible to emulate the start timer event using a normal
task with an timer boundary? or is the timer boundary not supported too?

Timer boundary is supported yes. You could emulate it, but that would mean that you will have to have one process instance active to fire the other processes

I thought of doing something like this:

a NOOP task should run in a loop till it is cancelled by the timer boundary,
thus emulating a start timer event. The flow continues to the task i want
to be executed periodically and a parallel gateway will continue with the
process and take care of starting the sequence again.
I have attached a diagram of what i am thinking of

I have not tried if this will work, and i am unsure how to proceed with the
results from the Importtask, as it will return a list of objects, which each
of them should be processed independently…
