Hi Carl,
Thanks for the tip.. that sounds like an excellent, clean tidy way to
tackle my problem.
When I have got a solution ready I'll put some POD on here for the
CookBook if you want.
cheers,

Hi,
I'd recommend writing a custom constraint class, rather than using Callback.
It just needs to inherit from HTML::FormFu::Constraint and have a sub
named 'constrain_value' which will receive the parameters ( $self,
$value, $params).
You can then access the Catalyst context via $self->form->stash->{context}
It can also define a 'constrain_values' sub to override how multiple
values are handled, or override 'process' to take complete control -
see the source of HTML::FormFu::Constraint for details.

Hello,
In my catalyst app I have a method that is used for a Callback constraint.
In my Root.pm controller use a session and log in a user the usual way.
package MyApp::Controller::ControllerA;
...
sub formfu_callback_checka
{
# need to validate using something in session?..
}
My question is, what is the best way to get hold of the session/user data
from within my callback method?
thanks for any help, apologizes if this gets asked all the time,
-Ben
