I am currently experiencing a problem where a select element's options
are not being populated when inside a repeatable element. This occurs
when the repeat method is called after process and the options are
populated by options_from_model. If I hard code the values for the
options, this problem does not occur. For example, assume the
following form definition:
- type: Repeatable
nested_name: order_lines
elements:
- type: Hidden
name: order_line_id
- type: Select
name: rc_order_line_status_code
label: Order Line Status
model_config:
DBIC:
resultset: RcOrderLineStatus
id_column: rc_order_line_status_code
label_column: description
--
Then, assume the following Catalyst code is executed:
...
$form->process( $c->request );
$form->get_element({ type => 'Repeatable' })->repeat(2);
Now, the order_lines element does properly get repeated twice in this
example, however, rc_order_line_status_code contains no options. If I
comment out $form->get_element({ type => 'Repeatable' })->repeat(2),
then the select box is properly populated. Therefore, this problem only
occurs when repeat is called a subsequent time after it is initially
called in process. Is this behavior a bug, or by design?
Looking at the source in HTML::FormFu::Element::Repeatable.pm, I was
able to create a temporary workaround that will populate repeated select
boxes by changing the following code in the repeat method from:
if ( $self->_original_elements ) {
# repeat() has already been called
$children = $self->_original_elements;
}
else {
$children = $self->_elements;
$self->_original_elements($children);
}
to:
# if ( $self->_original_elements ) {
#
# # repeat() has already been called
# $children = $self->_original_elements;
# }
# else {
$children = $self->_elements;
$self->_original_elements($children);
# }
Any help in solving this problem would be greatly appreciated.
Thanks,
Pete
