To do this, I think you'd need to create a Plugin.
Something like this should work...
form config:
elements:
- name: foo
plugins: DefaultFromContextStash
stash_name: 'varhash.key'
Then the plugin would look something like this:
(completely untested, of course)
package HTML::FormFu::Plugin::DefaultFromContextStash;
use strict;
use base 'HTML::FormFu::Plugin';
use HTML::FormFu::ObjectUtil qw( get_nested_hash_value );
__PACKAGE__->mk_item_accessors('stash_name');
sub process {
my ($self) = @_;
my $context = $self->stash->{context}
or return;
my $stash_name = $self->stash_name
or return;
my $value = $self->get_nested_hash_value(
$context->stash,
$stash_name,
);
$self->parent->default( $value );
return;
}
1;
