tr is not null, and contains the right transition. That's whay that's strange, like the end(tr) was not working...

tr Transition (id=140)
 condition null
 description null
 events PersistentMap (id=147)
 exceptionHandlers PersistentList (id=150)
 from TaskNode_$$_javassist_219 (id=155)
 id 4
 isConditionEnforced true
 name "refusee" (id=161)
 processDefinition ProcessDefinition_$$_javassist_185 (id=162)
 to Node_$$_javassist_254 (id=164)

taskInstance =jbpmContext.getTaskInstance(taskInstance.getID());

I tried your code though, but not working.

Here is my code to check if I'm on the right node :

Token currentToken = processInstance.getRootToken();
 Node currentNode = currentToken.getNode();


 if(currentNode.getName().equals("notifier_demande_refusee"))
 {
...

can you try

taskInstance.end(tr.getName())

can you try

taskInstance.end(tr.getName())

It doesn't make any difference (I already tried before).

When debugging, I get the followinf messages (allthough not debug but WARN messages...°:

WARN ProxyWarnLog:638 - Narrowing proxy to class org.jbpm.graph.node.TaskNode - this operation breaks ==
WARN ProxyWarnLog:638 - Narrowing proxy to class org.jbpm.graph.node.TaskNode - this operation breaks ==

All I see in the debug is that jBPM is taking the wrong transition. No error.

Here is the interesting part of the log :

GraphElement:180 - event 'node-leave" on 'TaskNode(valider_demande)' for 'Token(/)'
GraphElement:180 - event 'transition' on 'Transition(validee) for 'Token(/)'

One strange thing I noticed: when I try to know the active node, I'm doing:
Token currentToken = processInstance.getRootToken();
Node currentNode = currentToken.getNode();

The strange thing is that the token is not null, but every value of its properties is null:

currentToken Token_$$_javassist_187 (id=160)
 children null
 comments null
 end null
 handler JavassistLazyInitializer (id=183)
 id 0
 isAbleToReactivateParent true
 isSuspended false
 isTerminationImplicit false
 lock null
 name null
 nextLogIndex 0
 node null
 nodeEnter null
 parent null
 processInstance null
 start null
 subProcessInstance null
 version 0

Hum sorry but I don't have lot of time to build an sample of the error. I found a (dirty) way to do the job :
I noticed that although taskInstance.end(transition) doesn't work, token.signal(transition) does. So here is what I've done :

Transition tr=taskInstance.getTask().getTaskNode().getLeavingTransition("refusee");

 Token currentToken = processInstance.getRootToken();
 currentToken.signal(tr);

 @SuppressWarnings(value={"unchecked"}) //taskMgmtSession returns a raw List... We ignore the warning thrown by Java
 List<TaskInstance> userTaskList2 = taskMgmtSession.findTaskInstances(demande.getDemandeur().getUsername());

 for(int j = 0 ; j < userTaskList2.size() ; j++)
 {
 TaskInstance taskInstance2 = userTaskList2.get(j);
 if(taskInstance2.getProcessInstance().getId() == processInstanceId)
 {
 if(taskInstance2.getName().equals("valider_demande"));
 {
 taskInstance2.end();
 break;
 }
 }
 }
