Hi All: It looks like that we could only take a group task to the personal task list, but cannot put it back. The cancel() method in OpenTask will end the task. And I look at the gwt-console in the jBPM-4.0.CR1, it use taskService.take(dbid, null) to do the 'Release Task', I try it in my project and it failed with following exception: task already taken by username. I think if we could take a task, then we could release it, too. So, does this feature will be supported ? Or how could I impement it with current jBPM4's code? Thank you very much. 2009-07-01 Xu Huisheng
