Hi,
I've run into this problem as well. After poking around in the code
this morning, I've tracked the problem down to the call to
$block->repeat in H::F::Model::DBIC. This call apparently discards the
errors in a Repeatable block on any call to
$form->model()->default_values( $my_obj ). I've attempted to fix the
problem, and I've found that adding the following code to
H::F::Model::DBIC works, after a fashion (tested with Integer and
DependOn constraints):
# store our errors temporarily while the block repeats are built.
my %error_cache
= map { $_->nested_name => $_->get_errors }
@{ $block->get_fields() };
my $blocks = $block->repeat($count); # <----- the original
line of code.
# reinstate the errors.
foreach my $new_block ( @$blocks ) {
foreach my $new_field ( @{ $new_block->get_fields } ) {
foreach my $error ( @{ $error_cache{
$new_field->nested_name } || [] } ) {
# add the error to the field
$new_field->add_error( $error );
# reparent the error and its constraint.
$error->parent( $new_field );
$error->processor->parent( $new_field );
}
}
}
This feels pretty nasty to me (I'm worried I've missed some
reparenting, and there are probably edge cases I don't know about),
but hopefully it may point the way to others better acquainted with
HTML::FormFu internals.
Cheers,
Tim
