signal() or leaveNode() ??

[francis1970]

Hi all !
I'm using an ActionHandler to invoke a stored Procedure when some nodes are entered. This should simply invoke the stored Procedure, store the result in a variable and then move the execution to next node.

public void execute(ExecutionContext context) throws Exception {
 DBManager.getInstance.invokeStoredProcedure(params..);
 context.leaveNode();

 // or this ??
 //context.signal();
 }

Is it more appropriate to issue context.leaveNode() or signal() ? what is the difference between these two ??
Thanks
Francesco

From my reading of the docs http://docs.jboss.com/jbpm/v3/userguide/processmodelling.html, I'd say in this instance that leaveNode() is the better choice.

Under 'Node Responsibility':

2. propagate the execution over one of the leaving transitions of the node. This means that the token that originally arrived in the node is passed over one of the leaving transitions with the API call executionContext.leaveNode(String). The node will now act as an automatic node in the sense it can execute some custom programming logic and then continue process execution automatically without waiting.

Seems to do exactly what you require...
