Get task forms from RuntimeEventListener implementation

apita — Fri, 23 Feb 2018 00:39:36 GMT

I'm using Alfresco Process Services 1.7I've implemented a RuntimeEventListener for process lifecycle events and publish them out to a Kafka stream. It's working, but I was unable to fetch task's task_form on TASK_CREATED and/or TASK_COMPLETED events. I figured I'd be able to retrieve the task form w

APS uses a custom form service. If you designed and deployed the process in an APS app you should use AlfrescoTaskFormService.getTaskForm(taskId) instead.

Also, try wiring com.activiti.service.runtime.SubmittedFormService and use submittedFormService .getTaskSubmittedForm(taskId) for task complete events

I'm running your code on TASK_CREATED events inside the onEvent method of my RuntimeEventListener implementation. I successfully get the taskId, but I always get a similar error.

Task task = (Task) ((ActivitiEntityEvent) event).getEntity();
String taskId = task.getId(); // returns 192507

FormDefinitionRepresentation taskForm = alfrescoTaskFormService.getTaskForm(taskId);

Thanks. This works great for TASK_COMPLETED events, but I'm still having trouble fetching task forms on TASK_CREATED events.

Seems that the event is triggered before the form is created. If assignee is set on the task you can try TASK_ASSIGNED event.

Unfortunately, I get the exact same error on TASK_ASSIGNED events. Any other suggestions?

From the log trace you provided it seems to be a permissions issue. It can't find the history task because it's hasn't been created yet. You can get the form directly using the FormStoreService

formStoreService.getForm(delegateTask.getFormKey());

This worked on TASK_ASSIGNED events. I simply passed in task.getFormKey() to formStoreService.getForm. Thanks!

I'm glad that helped. Btw, that should work for any task event, it will provide the form regardless of the task state.

Apologies if the question seems too basic or invalid. I am new to Activiti and BPM.

I have an event listner and getting ActivitiEvent object.

ActivitiEvent event

How to get delegateTask object from it?

Thanks!

You can get the entity which should be a TaskEntity if it's ActivitiEntityEvent event and task related (i.e. type is ActivitiEventType.TASK_CREATED).

TaskEntity task = (TaskEntity) ((ActivitiEntityEvent) event).getEntity();
