That method is a remnant of the past, and it is deleted on trunk (or will be, today 😉

taskService.claim(null); does the same. Your task is then not assigned to an assignee anymore.

Hi Joram,

taskService.claim(taskId, null)

How to revoke the task in beta2?

This is most definitely a bug. I filed a Jira http://jira.codehaus.org/browse/ACT-206 and fix it asap!

Thanks!

What about adding the TaskService.revoke() operation to get a better API? claim(null) looks like a hidden feature.

We are doing exactly this in Grails Activiti Plugin API at http://code.google.com/p/grails-activiti-plugin/wiki/GrailsActivitiApi#Revoke_task

We originally had the revoke operation, but the meaning wasnt clear to everyone, so we decided to remove it.

Hey.
Short Question:
Is it possible to unclaim a Task via the REST-API?

The rest-api exposes a few operations that can be performed on a task. Unfortunately, the 'revoke' throws an UnsupportedOperation (with message "Not implemented in this version").
see org.activiti.rest.api.task.TaskOperationPut

With the current API, it should indeed be possible to do this. Can you file an issue for this?
