/**
* This class can be used as a drop-in replacement to struts' standard
* action form class.
* However, all form bean properties have to be of type
* <code>java.lang.String</code>.
* <p/>
* If you migrate from an existing struts application or want to use
* Calyxo Forms with the struts <code>html</code> tags, this class might
* be your choice. This action form implementation keeps the validated
* form data in a map, so it is available in your actions.
* <p/>
* You should insert a <code><calyxo-struts:flush></code>
* tag into your <code><html:form ...></code> tag to
* get your form bean properties updated with the formatted values, before
* they are displayed by the tags.
