[javi0704]

Hello,

I've just started using JBPM and I'm trying to create new State between 2 task-nodes.At the beginning the processDefinition look like this:
1) start-state-->task-node1-->task-node2-->end-state
but i would like to create a new State to Runtime when between this 2 task-nodes violation occur. So my ProcessDefinition have then a new State like this:
2)start-state-->task-node1-->newstate-->task-node2-->end-state

When I try to run the process, I get the following exception. Can anyone help please? My code looks like this:
==========================
Node currentNode = executionContext.getNode();
System.out.println("!!!----WhoIsCurrentNode: " + currentNode.toString());
Transition oldTrans = currentNode.getDefaultLeavingTransition();#to next1
Node nextNode = oldTrans.getTo();
System.out.println("!!!---WhoIsnexttNode1: " +nextNode.toString());
State stateNode = new State("WaitState"); //create me new stateNode
Transition stateTrans = new Transition();
currentNode.addLeavingTransition(oldTrans); 
oldTrans.setFrom(currentNode);
oldTrans.setTo(stateNode);
stateNode.addArrivingTransition(oldTrans);  
stateNode.addLeavingTransition(stateTrans);	    
nextNode.addArrivingTransition(stateTrans);	 
stateTrans.setFrom(stateNode);
stateTrans.setTo(nextNode);

When I try to run the process, I get the following exception. Can anyone help please? using server (jbpm-starters-kit-3.1.3)
