Strange behaviour query/signal multi instance receive task

aapthorp — Mon, 18 Feb 2013 21:46:21 GMT

I have a process with a multi instance receive task i.e. one instance for the number of messages I expect to receive before the receive task completes.When I query the receive task (as per the user guide but returning a list) I always get one extra execution returned. i.e. expect 2 get 3, etc. The r

I assume the reason for one extra task, is in effect a parent for each of the individual tasks, but then how is this stored in the database?

Yes, internally the executions are stored as a tree structure. In the case of multi instance, there is indeed a 'parent' execution stored in the database

At what point does the individual multi task get marked as ended? When each one is signalled?

Indeed. Each of the child executions need to be signalled before the process continues.

I must admin, I think we haven't tested a multi instance receive yet. There aren't many use cases for it, but still it should work. Do you have a sinple unit test that demonstrates the problem?

Thanks, this starts to make a bit more sense.

Question, how do I detect which instance has already been signalled? I can see that one gets marked as inactive in the database. I assumed that Execution.isEnded() would tell me which one is complete, but seems to return false even for the inactive instance.

Interestingly my jUnit example returns the parent last and not first from the executionQuery.

No, inactive means something different than ended (ended is actually an edge case, cause it really means the flow has stopped, which typically means they won't be in the database anymore).

Can't you use ExecutionQuery activityId(String activityId); to fetch the executions which are specifically on the receive task?
If that query also returns the parent or any already signalled children then we've hit a limit of Activiti and we'll have to add some new logic I'm afraid.

Interestingly my jUnit example returns the parent last and not first from the executionQuery.

The order of how they are returned is not specified, ie. that will be database specific.

Indeed this is what I'm doing - line from my jUnit test (happy to provide the whole test) as follows:

List<Execution> executionList = runtimeService.createExecutionQuery()
        .processInstanceId(processInstance.getId())
        .activityId("receivetask1")
        .list();

So some new logic needed in Activiti then?

In the meantime I'll see if I can fix this with a native query. Am I correct in thinking that I want executions with the database column IS_ACTIVE = true ?

Re: Strange behaviour query/signal multi instance receive task

aapthorp — Wed, 20 Feb 2013 21:01:33 GMT

List<Execution> executionList = runtimeService.createNativeExecutionQuery()
        .sql("SELECT * FROM ACT_RU_EXECUTION WHERE ACT_ID_ = 'waitWeighed' AND IS_ACTIVE_ = 'TRUE'AND IS_SCOPE_ = 'FALSE'")
        .list();

Seems to do the trick, even with a normal single receive task.

Ok, interesting find. I'll see what makes most sense in Activiti and fix it, because this is definitely a bug in my opinion.

Thanks. Will you add to Jira?

Re: Strange behaviour query/signal multi instance receive task

jbarrez — Thu, 21 Feb 2013 17:13:40 GMT

Well, I've done some investigation in the meantime. And indeed, it solves the problem for multi instance receive … but it breaks the tests for a lot of other stuff. For example for boundary events which are scopes (ie IS_SCOPE_ = true) and don't have a parent….

So currently I'm not really sure what a valid solution would be. I'll discuss it tomorrow with the rest of the team.

Re: Strange behaviour query/signal multi instance receive task

jbarrez — Fri, 22 Feb 2013 10:54:20 GMT

Okay, managed to fix it and make it work for all the other cases.

See http://jira.codehaus.org/browse/ACT-1586

So the 5.12 release will have this fixed!

Great, that was quick - thanks.

Your test case imports all kind of funny stuff (eg com.procurics.rnd.model.*).
I cant run the test this way without the dependent code.

Getting the same error on line 104 in 5.13.1. The error occurs while attempting to complete the last task of a process instance (using the REST API to complete). The process definition has a multi-instance subprocess, but the last task is not within this subprocess. Will post a solution if I find one.

Fixed. The Eclipse designer did not show it, but the human task had 2 flows coming out of it, one of which went to an end activity, and one of which went to a service activity. Removing the second flow solved the problem
