[html-formfu] More complex DBIC/FormFu interaction

[Nigel Metheringham]

Just to follow up to my own message...

I won't rehash the problem, but I will present the solution in case
anyone else is trying something similar...

The YAML form config should be changed to
   elements:
     - type: Checkboxgroup
       name: bookings
       model_config:
         label_column: text_info
         resultset: Booking
         attributes:
           order_by: start
           prefetch: booking_type
         condition_from_stash:
           event: event_id

and then the following code should be added before the 
# check and process form
section of the code:-
    # stash event restriction for use within form
    $form->stash->{event_id} = $event->id;
    $form->process;

The additional process step is needed (otherwise the value is taken 
from when the previous process was run within the 
Catalyst::Controller::HTML::FormFu superclass.


Carl: this isn't documented, but there are tests - thankfully which
makes it much easier to work out whats happening.  I'll see if I can
come up with a doc patch for it.

	Nigel.
