this is what i added to the migration docs especially for you :-) anonymous wrote : The root execution is now the same object as the | process instance. (In jBPM 3, the ProcessInstance had | a pointer to the root token). Also, unlike in jBPM 3, executions in jBPM 4 might | get inactivated, create a child execution and let the child execution continue, even | when logically this represents only one single path of execution. This happens in | scope activities (or composite activities) that have timers or variables declared. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4242575#...
