When you query on tasks with a candidate group you are automatically querying on tasks that are unassigned. Tasks that are assigned, don't have a candidate group / user anymore in the task lifecycle of Activiti. the method taskCandidateOrAssigned on TaskQuery might return the result you are looking for.
