[Catalyst] C::C::FormBuilder - Forwarding to another action overwrites data from the calling action

[Danny Warren]

Yep, that sequence of events is exactly what I am seeing.  Hooray, I am 
not crazy!  (well, on this one thing...)

One way I was thinking of getting around this was to do the same thing 
you suggested with the template vars for the $controller->_formbuilder 
data - create named aliases (at step 1 and 1a below) so that the CGI::FB 
object can be grabbed even if clobbered by the forward.  I will try this 
out while you are checking in to things yourself (I haven't done it yet 
because it doesn't look clean to implement, and I thought I was doing 
something really wrong).

What I guess we would end up with is an FB::Multiple module that:

1) Still provide the normal ways of getting at form data, so that your 
actions with no forwards still work like normal (ex: [% 
FormBuilder.render %] and $self->formbuilder)

2) Provide an alternate way of getting at form stuff, so that you can 
get data even if you are using forwards (ex: [% 
forms.foo.FormBuilder.render %] and $self->forms{foo} or 
$self->forms_foo - still haven't decided on a naming scheme)

Will send you my test app in a moment.

Thanks again!
