Rose::HTML::Form::Field::DateTime::Split::MonthDayYear a compound field for dates with separate text fields for month, day, and year.
This class inherits (indirectly) from both Rose::HTML::Form::Field::DateTime and Rose::HTML::Form::Field::Compound. This doesnt quite work out as expected without a bit of tweaking. Wed like inflate_value() and validate() methods to be inherited from Rose::HTML::Form::Field::DateTime, but everything else to be inherited from Rose::HTML::Form::Field::Compound.
To solve this problem, theres an intermediate class that imports the correct set of methods. This class then inherits from the intermediate class. This works, and isolates the tricky bits to a single intermediate class, but it also demonstrates the problems that can crop up when multiple inheritance is combined with a strong aversion to code duplication.
Inheritence shenanigans aside, this class is a good example of a compound field that also provides an inflated internal value (a DateTime object).
It is important that this class (indirectly) inherits from Rose::HTML::Form::Field::Compound. See the Rose::HTML::Form::Field::Compound documentation for more information.
Get or set the date parser object. This object must include a parse_datetime() method that takes a single string as an argument and returns a DateTime object, or undef if parsing fails.
If the parser object has an error() method, it will be called to set the error message after a failed parsing attempt.
The parser object defaults to Rose::DateTime::Parser->new().
If the parser object has a time_zone() method, this method simply calls it, passing all arguments. Otherwise, undef is returned.
