I see, I have always been used at wrapping forms in a div with id even in TW1, so I never found this issue before.
I think it is probably a tw2 bug as the right behavior is the one you get when you don't specify the id. The id of the root element should probably not be added to the field names. About the fieldset behavior, that is the expected one. If I'm not wrong, It was like that also on TW1. To unpack the arguments you just have to add @validate(MovieForm) to your index controllers and it will receive the arguments in nested dictionaries instead of multiple arguments separated by colon. Adding @validate should fix also the behavior with ID as it will unpack those too.
