Hi, I have now implemented this ForEachForkHandler and it works. However, I have now come up with an extended scenario. In my ForEachForkHandler I create 4 tasks. However, in specific situations I want already to continue when the first two tasks are completed. Therefore, I have tried to implement a kind of housekeeping handler which I call from the join to get rid of the "unnecessary" tasks. My process consists of 1) fork 2) 4 activities which have been generated by the ForEachForkHandler 3) join When entering the join I call setNOutOfM with an appropriate value. Secondly I invoke the handler listed below: | ublic class MultiinstanceHouseKeepingHandler implements ActionHandler { | | @Override | public void execute(ExecutionContext ctx) throws Exception { | // TODO Auto-generated method stub | Token t = ctx.getToken(); | Collection til = ctx.getTaskMgmtInstance().getTaskInstances(); | Map childTokenList = t.getParent().getChildren(); | Set ks = childTokenList.keySet(); | Iterator it = ks.iterator(); | while (it.hasNext()) { | Token ct = (Token)childTokenList.get(it.next()); | if (ct == t) | continue; | Iterator itil = til.iterator(); | while (itil.hasNext()) { | TaskInstance ti = (TaskInstance)itil.next(); | if (ti.getToken() == ct) { | ti.cancel(); | ct.end(); | break; | } | } | } | } | } | The process continues correctly with the task following the join. However, I cannot get rid of the other unwanted tasks and they stay forever on my worklist. What am I doing wrong here?
