[Catalyst] Catalyst::Controller::DBIC::Transaction Integration

[David Schmidt]

Hello Carl and thanks

I already attempted to solve the problem with changing the order of
the parent classes. I still get the same error

Can't call method "submitted_and_valid" on an undefined value at

... and so on.

ps: I read and implemented your approach to formfu validation through
a custom validator rather then a callback yesterday, thanks for that.
