DESCRIPTION

Rose::HTML::Form::Field::Set is a subclass of Rose::HTML::Form::Field::TextArea that accepts whitespace- or comma-separated strings. Its internal value is a reference to an array of strings, or undef if the input value could not be parsed.

Strings with spaces, double quotes, backslashes, or commas must be double-quoted. Use a backslash character ``\'' to escape double-quotes within double-quoted strings. Backslashed escapes in double-quoted strings are interpolated according to Perl's rules.
