Timer Catching Event is executing only once even when Interval is Set

Hi,What is wrong with the following process definition<process id="timer_catching_event" name="My process" isExecutable="true"> <endEvent id="endevent1" name="End"></endEvent> <startEvent id="startevent1" name="Start"></startEvent> <intermediateCatchEvent id

The script will execute only once based on your bpmn20.xml. If you want some looping logic with a time delay, you will need to implement the loop in your bpmn diagram and exit out of the loop based on a loop counter stored in a variable. Another option is to group the activities in your loop in a sub-process and configure the multi-instance properties on the sub-process (http://www.activiti.org/userguide/#bpmnMultiInstance) according to your requirement.

Thanks cjose,

But Then I don't understand what does "R4/PT10S" would do.
As far as I know R4 means repetition.
What would it repeat then ?

"R4/PT10S" is the notation of repeatability. However I don't think it can be used with an intermediate timer event.

Thanks cjose,
Can you specify where repeatability is allowed and where not
Eg. In Timer Start Event, Timer Boundary Event and Timer Catching Event …

Him piyush,

intermediate timer events are acting like "stopwatch"
see details here:
http://www.activiti.org/userguide/#bpmnTimerIntermediateEvent
http://www.activiti.org/userguide/#timerEventDefinitions

Another good source of examples is the tests we have in the source code. (inspecting these tests you can learn a lot of things about how Activiti is expected to work)

Thanks vasile.dirla ,
My question is Timer Catching events don't reoccur if i set Time Cycle as "R4/PT10S".

Hi Piyush,

Yes, you are right the R is ignored in case of an intermediate catch event of type timer. (because the purpose of the intermediate catching event of type timer is to act as a stopwatch.)

so this construction:

<code>
<intermediateCatchEvent id="timerintermediatecatchevent1" name="TimerCatchEvent">
<timerEventDefinition>
<timeCycle>R4/PT10S</timeCycle>
</timerEventDefinition>
</intermediateCatchEvent>
</code>

will ignore the "R4" part of the definition.
