Thanks for your attention , as the image above, I create a “multiTask” UserTask which has multi instance, if I have two instance when it comes to “multiTask” , such as A and B, then I create dynamic task C for A , and dynamic task D for B（by DynamicUserTaskBuilder or (TaskSerce.newTask and setParentTask) ）. now A-\> C and B-\>D two instance, each one has two sequential tasks , once I completed A and B , the processes run to the “afterMulti” UserTask, that’s not I want, it seems that dynamic task doesn’t change the workflow dependency. how can it comes to “afterMulti” UserTask only if dynamic C and D are completed , anyone helps please,  
Thanks a lot 😀

Hi Edward,

Add `UserTaskEventListener` on complete event to `multiTask`. EventListener can check whether all “children” are completed.
