Hi, I just voted:)

Regarding your doubts:

I think you are going in exactly the right direction. As I understand it (correct me if I'm wrong!), information about how the user can interact with the process instance in jBPM 4 is currently meant to be provided with task forms. A reference implementation exists for the GWT console. However, I totally agree with what Sebastian stated earlier:

anonymous wrote : If you want the user to make this decision you need this information and since it is supplied by the process definition it should be accessible trough the API.

For use cases where no user input - other than a decision - is required, this would provide a very nice way to create dynamic user interfaces without the need for a custom task form implementation.

And while we're at it, wouldn't it also be nice to be able to query the process instance for the process variables that will be required after a transition? ...but now I'm getting ahead of myself:)

Anyway, I'm glad to see this discussion here!

Cheers, Nils
