I did reply, but here it is again, in case it didn't get through to the list:.
(short answer is: there is a couple of ways to work around it, but it
can't be fixed)
...
Filters are run before Constraints.
So by the time the 'enddate' Required constraint tries to run, the
CompoundJoin filter has already munged the hashref into a string.
I think the only way around this, is to instead attach a constraint to
the Multi block, which checks the filtered value is logically correct.
Alternatively, I suppose you could create a new Required constraint,
which instead checks the value was present in the initial input,
rather than the value that's fed to the constraint.
Something like this should work:
package HTML::FormFu::Constraint::PreFilterRequired;
use strict;
use base 'HTML::FormFu::Constraint';
sub constrain_value {
my ( $self ) = @_;
my $form = $self->form;
my $name = $self->parent->nested_name;
my $value = $form->get_nested_hash_value( $form->input, $name );
return defined $value && length $value;
}
1;
