Does the TaskNode.addTask(task) method works well? I'm printing my process definition to check if is well builded and everything appears well excepts the tasks that don't appear! Any idea why they don't appear? Probably this is why is not working programmatically and yes with the xml defintion I'm using JpdlXmlWriter.toString(pd); . I know is deprecated, but is just to check if the process definition defined programmatically was well builded thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4199894#...
