Help with a subprocess query

rmoskal — Wed, 02 Mar 2011 04:35:53 GMT

I have a little workflow that includes this excerpt here: <sequenceFlow id="flow1" sourceRef="theStart" targetRef="model"/> <callActivity id="model" name="Model" calledElement="minimum_concrete_flow" /> <sequenceFlo

You want to get a list of tasks through the API ?
I give my usertasks certain names, for instance:

  
<userTask id="CORRECT_THE_ORDER" name="CORRECT_ORDER" activiti:formKey="/main/order/submitOrder">
</userTask>

You can then use the name of the usertask as a parameter in the API.


List<TaskEntity> taskList = (ArrayList)taskService.createTaskQuery().taskName("CORRECT_ORDER").taskUnnassigned().list();

Not sure if that's what you mean ??

Tom.

Thanks Tom. But that's not quite what I mean. The tasks are in the subprocess and the subprocesses are all the same. You'll notice the call statements. Each task is associated with the activity in the main process. I need to query them in bulk to get all the tasks associated with each node in the top level process.

I think I can create a listener to decorate the subproc with the name of the node. Then I can use a query that looks at that variable. I will try it today.

Thanks,

Robert

You coud use the historyService.createHistoricActivityInstance.activityId("your id").
Note that its called 'history', but is is always reflecting the runtime state.
You would need to have history enabled for that though.

Hi all,
I have the same problem rmoskal had last year. I tried your solution but it can't work since it has as an input what I need as a result. In other words, given an HistoricActivityInstance object representing a callActivity, is it possible to access all the activities in the subprocess called? Thanks,
Massimo

Same problem here, Do you find a solution ?

Hi,

In the trunk I've committed an extra method in the HistoricProcessInstance where you can retrieve all sub processes of a specific process instance id.
It's called superProcessInstanceId(). Does this solve your problem?

Best regards,
