[html-formfu] Error messages in fields within a Repeatable

[michele.gherlone at liceoberchet.it]

Hello all!
I have set up an application in Catalyst where an action has the following
form:
---
indicator: submit
elements:
  - type: Repeatable
    increment_field_names: 0
    nested_name: my_rep
    tag: tr
    elements:
      - type: Block
        tag: td
        content:
        elements:
          - type: Label
            name: studente
      - type: Block
        tag: td
        content:
        elements:
          - type: Text
            name: voto_orale
            constraints:
              - type: Regex
                regex:
'^ms$|^m$|^suf$|^sc$|^10$|^10-$|^\d\+$|^\d\-$|^\d\.25$|^\d\.50$|^\d\.75$|^\d$'
                message: Il voto non e' nel formato corretto...
          - type: Text
            name: data_orale
            constraints:
              - type: Regex
                regex: '\d{2}\/\d{2}'
                message: La data non e' nel formato corretto...
          - type: Text
            name: comment
      - type: Hidden
        name: materia_id
      - type: Hidden
        name: studente_id
      - type: Hidden
        name: quad
  - type: Submit
    name: submit
    attributes:
      value: Registra definitivamente i voti
filter:
  - TrimEdges

The form is populated with a hashref I create from parameters passed by
another form, calling $form->model('HashRef')->default_values($hr). The
Repeatable block works as expected, and I get as many 'tr' as the number
of hashes inside the array @{$hr->{my_rep}}.
However, when $form->has_errors is true, I can see the correct number of
messages, but *ONLY* the first block, while I'd like to get the error
messages along with all the blocks repeated as when the form is rendered
the first time (i.e. when !$form->submitted).
I understand the issue is not simple, and I hope I exposed it as clearly
as possible.
My question is whether it's not possible to achieve my goal, or I am doing
something wrong, and it IS indeed possible to have multiple error messages
displayed along with the repeated blocks, in a context like the one I have
depicted here.
Thank you in advance for the help I really need!
Regards,
Michele Gherlone
