DESCRIPTION

Provides pre-loaded values to the Form Template in which it resides. The query may return multiple values, in which case it will create an array of hashrefs data structure appropriate for an Apache::Wyrd::Input::Complex input if it is flagged to do so with a "complex" or "multiple" flag.

The preload requires an Apache::Wyrd::Query object to be embedded in it. It can also accept a Apache::Wyrd::Defaults object.
