[jbpm-users] searching for Tasks even if already assigned (jBPM v4.0.B1)

Hi All, currently I'm evolving jBPM 4 to find out if it is suitable for our requirements. Now I'm not sure how to meet some requirements. Here the Situation: I've a task with an entry in the "candidate-groups", and I'm finding the task with the "findeTakableTasks" function. After assigning the task to somebody the task disappears from the "findeTakableTasks" function. To meet requirement I need a function to see ALL (not finished) tasks for one group (candidate-groups), even if the task is already assigned to somebody. is there a way to retrieve such a list? And another question is: is there a search function to search for tasks? I would like to search for special variable with special values or for tasks in a special status and so on. Thanks for your reply sirfrancis
