HTML::FormFu::Filter::ForceListValue(3p)

NAME
HTML::FormFu::Filter::ForceListValue - convert a single value into a 1-item-list

VERSION
version 2.07

SYNOPSIS
    element:
      - type: Repeatable
        increment_field_names: 0
        elements:
          - name: foo
            render_processed_value: 1
            filter:
              - ForceListValue

DESCRIPTION
Causes a single submitted value to be changed to a list containing 1 item.

Solves an uncommon problem with a Repeatable block with increment_field_names disabled, when manually increasing the repeat count after the form was submitted with only a single value for each of the Repeatable's fields.

If these circumstances, when rendered, every repeated field would have the initially-submitted value as its default.

Using this filter, and setting render_processed_value to "true" will ensure that only the first repetition of each field will have the submitted value as its default; all subsequent repetitions will have no default value.
