Hi all,

I am looking at replacing jBPM 3 with 5 and there is one feature of 3 that we use extensively that I am not sure how to do in 5 - we send to the client application (not a web app) the set of transitions that the current user is able to take for the selected task. This allows us to alter and redeploy a workflow and have the UI automatically pick up new/changed transitions. 

I gather that in version 5/BPMN2 outgoing transitions would be implemented by an XOR split that would use data added in the completion of the task node to choose the correct path, but I have not seen any examples where you can retrieve the set of valid transitions from anywhere. Before I go ahead with some custom implementation is there some recommended way to do this, or a different approach I should be using?

thanks in advance
