Hi,

Instead of using JumpActiviti(Doesn't look to be from Activiti) why dont you have a sequence flow from user task3 to user task2 on disapproval/rejection ?

because, which task node should jump to depends on configuration data in the non-activiti data tables, and I don't want the draw exclusive-gateway to realize the disapproval. cause any task node would be a target node when disapproval/rejection happened.

Hi,
I've make some changes to JumpActivitiCmd.java to fix the error, but I'm not really sure it's a proper solution or it may introduce another error later

Even though it was successfully (or properly ended), some potential bug or issue need to address
1. refer to successLog
1a. line 24, userTask3 for mazi was created, but TaskCompleteListener wasn't triggered
1b. line 41, instead of mazi, wanger was assigned to userTask3

thanks , faizal-manan.

code is userful for me!

and the additional error could be resolved with other ways..

for the 1a line 24, I can't reproduce the error. it work well for my case.

for the 1b. line 41: we can set the assignee to mazi before completing the user Task2

hi windfighter,
you're right, (1a) doesn't trigger any error, but since I register completeTaskListener to every single user task, it should appear in a log upon calling taskService.complete()
As you can see from the log, completeTaskListener for userTask3 is fired during 2nd iteration (refer to line 45) and the question is where's the 1st completeTaskListener log for userTask3?

hi, faizal-manan

in the log line 25: (TaskCreatedListener.java:18) - [5-21] Task Created: usertask3(User Task3)

task was created , and assigned to `mazi`.

then we execute the jump command ( managementService.executeCommand(cmd); )

when the jump command executed, the activiti actually jump from `user task 3` to `user task2`,it does't complete the complete the `user task3` , so there is no completeTaskListener log for the user Task3.

hi windfighter,

did you have any idea which part of incomplete complete task?

Re: problem with jump to a multi-instance user task

windfighter — Wed, 18 May 2016 03:14:19 GMT

hi faizal-manan,

there is no code to complete the `user task3` in the testJump function.

could you please indicate which line to complete the `user task3` ?

just duplicate the last 2 LOC
<code>
printExecutions(pi.getProcessInstanceId(), "after jump to user task2");

        completeTask(pi.getProcessInstanceId(), null);
        printExecutions(pi.getProcessInstanceId(), "after complete user task2-instance1");

        completeTask(pi.getProcessInstanceId(), null);
        printExecutions(pi.getProcessInstanceId(), "after complete user task2-instance2");

        completeTask(pi.getProcessInstanceId(), null);
        printExecutions(pi.getProcessInstanceId(), "after complete user task3");
