Event to skip to a different node in the Process?

[rrpeterson]

Hi guys,

I've got a process/process instance with several nodes, something like:
start -> sendEmail -> 3-day timer -> send 2nd email -> 3-day timer -> send final email -> wait 3 days -> end

If the user opens the email and clicks a link, I'd like to send an event to JBPM to move them into a 2nd process (or branch of this process).  The click could happen at any time/node within the process after the first sendEmail node.  Is it possible for an event to enact this type of behavior?

Thanks in advance for any suggestions!

Hi Ryan,

You can create a HumanTask like a parallel branch for each timer. Then  user will complete the HumanTask, and process will moved to next node immediately.

Rgds,

Thanks Bob, that does seem to make the most sense.  So in the previous example:

start -> [sendEmail] -> [3-day timer] -> [send 2nd email] -> [3-day timer] -> [send final email] -> [3-day timer] -> end

                                     |event|                                           |event|                                             |event|

                                                                                 [newServiceTask] -> [x-day timer] -> [etc..]

Anytime the event gets triggered while in the timer states, they would know to proceed through to [newServiceTask] rather than continuing on the previous node path. 

I'll give this a shot & report back, thanks!

I wound up using a diverging eventBasedGateway.

Two nodes extend from the eventBasedGateway, the first is a timer, the second is an event.  Whichever occurs first invalidates the other path, and execution continues from that node onwards.
