Getting null value while calling Message catching event

Hi,AS per the client request, we need to insert values to multiple tables in the same flow (more than 10 tables) so I created multiple service tasks- one for each table, Inorder to handle db issue i added error boundary event on each service task and calling a call activity (fault handling process)

I'm not sure that messages will work through a call activity (I don't even think it is valid BPMN 2.0).

And embedded subprocess will work, but that won't solve your problem probably.

Hi ,

Is it possible to add boundary and Intermediate events to call activity? I hope we can add error boundary event and timer event other than that any other event is possible? Because when i try to call message boundary event of call activity from call activity, I m getting null.
If it is possible to call, then plz share some reference document it will be very much helpful for me.

Timers will work, but passing data using events is not something that will work.
The right BPMN 2.0 way to do it, is to have multiple processes in one definition file and define message exchange between them. However, that is unfortunately not implemented in Activiti.

You could, however, create a similar behavipur using custom service tasks and receive tasks to continue/halt processes based on messages.
