Get ActivityInstance from another task

Q&A
1

Hi everyone.

I'm working in an email notification task.

I'm trying to know if a task is assigned to a user or not.

If the task is assigned to a user I need the email of this user to send the notification, or if the task is unassigned I'm sending the notification to all the possible users.

If I want to extract this information from another task, i found the method getHumanTaskInstance from the processAPI(), but I need the activityInstanceId from the other task to obtain the information.

How can I get the activityInstanceId from another task?

Thanks.

Hello,

What do you have to search the another activity instance? A CaseID and a task name ? 

So use the Search operation (I'm not sure about the ActivityInstanceSearchDescriptor constant, have a look in the javadoc)

      SearchOptionsBuilder searchActBuilder = new SearchOptionsBuilder(0, 1);
            searchActBuilder.filter(ActivityInstanceSearchDescriptor.ROOTPROCESSINSTANCE, MyCaseId);

            searchActBuilder.filter(ActivityInstanceSearchDescriptor.NAME, "MyTaskName");

           SearchResult<ActivityInstance>  searchFailedActivityInstance = processAPI.searchActivities(searchActBuilder.done());

if (searchFailedActivityInstance.getCount()>0)

activityInstanceId = searchFailedActivityInstance.getResult().get(0).getId();

 

 

By the way your use case seem to be take into account by the Email User job in TruckMilk
