I am trying to set up a workflow that includes a task assignment to a director. The requirements are that the director simply be able to check out the document, review it, electronically sign it and then check it back in. I have tried to use the complete workflow task action (for testing I just set it to complete after 1 minute), but the workflow doesn't ever move past the task assignment step. Are there any special requirements to get this to work? The help on these actions is really not very helpful.
