> Let's consider a simple example using a super-state :
> <start-state name="start">
>         <transition to="buildPhase"/>
> </start-state>
> <super-state name="buildPhase">
>         
>    <event type="superstate-enter">
>       <action class="com..." />
>    </event>
> ...
>    <state name="waitForValidation">
>       <transition to="../deliveryPhase"/>
>    </state>
>    <event type="superstate-leave">
>       <action class="com..." />
>    </event>	
> The superstate leave event is fired, but enter is not.
> Looking at the code this seems 'normal' :
> - Transition.take:
> if ( destination.getSuperState()!=null ) {
>     ... fire the event ... 	
> - SuperState.execute :
> Node startNode = (Node) nodes.get(0);
>     startNode.enter(executionContext);	
> Going from a node to a super-state taking an explicit transition wont cause the event to be fired as dest.getSuperState == null.
> Then the super state will be executed and the first node will be entered without any kind of 'transient' transition being taken.
> If we look at the doc : (http://docs.jboss.com/jbpm/v3/userguide/processmodelling.html#superstateevents )
> 9.6.2. Superstate events
> ...
> These events will be fired no matter over which transitions the node is entered or left respectively	
> -> I cant find anything more precise about the expected behaviour
> AFAIAC I would expect the super-enter event being fired whatever the enter context (thru an innder node, or referencing the super-state itself).
> Best regards
