I've just committed a change to task forms navigation. In addition to making this component one step closer to being completely reusable outside of the console, this change allows proper navigation from task forms when transitions are taken. Now when you take a transition, you are taken to a screen that lists all the task assignments that resulted from your action, or else you're taken to a "Done" page.
Currently task forms (and the console in general) more or less ignores the actor ID and just lists everyone's tasks and lets anyone modify any of them. I am aware of this and it is not my intent to keep it this way. This is just so I can get the hard part (the components) done.
Let me know here if you run into any problems with the new task form handling. Further discussion on navigation should be kept to the navigation thread in these forums.
