[SWF2.0.0] inheritance and subflows - Possible Bug

[jamesclinton]

Inherited flow doesn't work when returning to a sub-flow.

Scenario:

* Abstract flow definition of global menu transitions.

* Flow starts then triggers a subflow.

* Menu clicked when in subflow (results in error 'No transition found on occurrence of event')

* Adding the GT transition (which should of been inherited) into subflow-state resolves the problem but defeats the point sadly.

Workaround:

<subflow-state id="edit.subflow" subflow="some-flow">		
   .
   .	
   <transition on="*" to="${currentEvent}"/>  
</subflow-state>

James,

I'm wondering if this is an issue with flow inheritance or with subflows using a global transition. Can you try moving the transition into the global-transitions block of the concrete flow definition.

If that works, then this is an inheritance issue. If not it is a subflow issue.

Either way, please open a JIRA.

Adding the GT in the concrete flow did not resolve the problem.

Having looked into this further I don't think there is a problem with SWF2.0. I was missing a set of GT's to handle the end-state ID returned from the sub-flow.

This was why my workaround <transition on="*" to="${currentEvent}" /> works because 'currentEvent' equals an inherited <end-state> which then starts a new flow via flowRedirect.

Hope you didn't spend much time of looking into this yet!
