[html-formfu] probably bug in nested forms

[Mario Minati]

Hi,

while reworking the DBIx::Class::HTML::FormFu::fill_formfu_values I found 
misformed nested_names:

YAML config of elements (constraints removed for readability):
---
elements:

  - type: Fieldset
    legend_loc: Description
    nested_name: description2
    elements:

      - type: Text
        name: description
        label_loc: Label

      - type: Multi
        label_loc: Use for
        container_attrs:
          class: vertical
        elements:

          - type: Checkbox
            name: use_for_shipping
            label_loc: Shipping

          - type: Checkbox
            name: use_for_routing
            label_loc: Routing

          - type: Checkbox
            name: use_for_billing
            label_loc: billing


I dumped the nested_names in DBIx::Class::HTML::FormFu::fill_formfu_values 
like this:

...
    for my $field (@$fields) {
        my $field_name = $field->name;
        my $field_nested_name = $field->nested_name;
warn $field_nested_name;
        next unless defined $field_name;
...

And here is the output:

description2[description] 
at /home/mario/Desktop/dev/projects/formfu/svn/trunk/DBIx-Class-HTML-FormFu/lib/DBIx/Class/HTML/FormFu.pm 
line 37.
description2[description2][use_for_shipping] 
at /home/mario/Desktop/dev/projects/formfu/svn/trunk/DBIx-Class-HTML-FormFu/lib/DBIx/Class/HTML/FormFu.pm 
line 37.
description2[description2][use_for_routing] 
at /home/mario/Desktop/dev/projects/formfu/svn/trunk/DBIx-Class-HTML-FormFu/lib/DBIx/Class/HTML/FormFu.pm 
line 37.
description2[description2][use_for_billing] 
at /home/mario/Desktop/dev/projects/formfu/svn/trunk/DBIx-Class-HTML-FormFu/lib/DBIx/Class/HTML/FormFu.pm 
line 37.

So the nested_name 'description2' gets repeated two times, probably because of 
the Multi element in the config.

I'll go hunting ;-)

Greets,
