NAME

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

VERSION

       version 2.05

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.
