Driving Menus Using BPMN

izaak — Thu, 15 Nov 2012 14:10:06 GMT

I'm trying to drive my app's menu system via the process only, the first way to do this that occured to me was to find outgoing sequenceFlows for a given exclusive gateway. Reading this post:Is this correct way to get outgoing transitions?, and this post Querying ExclusiveGateway and other gateways.

Your analysis is correct. The 'right' BPMN 2.0 way to do it is indeed duplicating that information in the choice for the user and in the sequenceflow.

If it is a matter of the user selecting themselves which sequence flow to take, you could look into adding those sequence flow without an exclusive gateway, straight out of the task …. However, you would need specific conditions on the outgoing sequence flow still, something like 'sequenceFlowId == blah'.

So another thing you could do, is write your own activitybehaviour that only takes one outgoing sequenceflow instead the default way of taking everything in parallel.

Or parse the xml and get the information from the conditions on the sequence flows

In the 5.11 release, we'll have an easy xml -> pojo parser in there which you can use as enhancement on Ronald's suggestion.
