/**
* Generic Calyxo action form class for use with the Calyxo Forms tags.
* Valid form data is kept in a map.
* <p/>
* The input values to be validated are directly taken from the request.
* Struts users should not derive from this class to add form bean
* properties they are do with ordinary action forms: the populated bean
* properties will neither be used as inputs to the validation, nor
* will the Calyxo input tags get their values out of these properties.
* <p/>
* Again: this implementation does not use bean properties or mapped
* properties and does not work with the form input tags shipped with struts!
* If you want to use "legacy" action forms with the struts tags, take
* one of the action form base classes from the
* <code>de.odysseus.calyxo.struts.forms.legacy</code> package.
