Solution In Progress - Updated -

Issue

  • I am getting a PermissionDeniedException when trying to forward a human task. My task is assigned to a group "group1". "group1" has "user1" and "user2". After started the process, this task is in a 'Ready' State, and potential user1 forwards the task to potential user2, but it throws a PermissionDeniedException.
caused by: org.jbpm.services.task.exception.PermissionDeniedException: User '['UserImpl:'user1']' does not have permission to execution operation 'Forward' on task id 391

  • After the task is forwarded, when I "user1" query for getTasksAssignedAsPotentialOwner I should not see task return to me. But, I still this task return to me.
