Scull, I doesn't understood. But now It works. At the end of all my attempts I resolved. Continue reading to know all the story.. Hope this will help someone. I moved The action that creates all the dynamic tasks to the node-enter of the task to "clone" (if you followed the example in the previous post, the task in tCompDoc) This is the code of dynamic creation: | Token token = executionContext.getToken(); | TaskMgmtInstance tmi = executionContext.getTaskMgmtInstance(); | TaskNode taskNode = (TaskNode) executionContext.getNode(); | Task task = taskNode.getTask("task compilazione"); | TaskInstance taskInstance = tmi.createTaskInstance(task, executionContext); | taskInstance.setActorId(user); | But the important part of this is the execution point. Remembar "node-enter of the cloning task". Elsewhere will cause errors and token scramble. In my sample I need a task to close every dynamic task created early, still not ended, I put this code to the node-leave of chiusura-interpello. This is the relevant part of code: | if (!ti.hasEnded()) | ti.cancel(); | thanks to every one helped me to achieve this goal Hoping this will help someone else. If you have any question, ask. bye View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4147466#...
