 The reasoning behind this is to give form bean developers
 control over the lifecycle of their multipart requests

 methods of <code>MultipartRequestHandler</code>.  This method will return
 <code>null</code> if this form's enctype is not
 "multipart/request-data".</p><DD><DL>

<DL>
<DD><p>Reset bean properties to their default state, as needed.  This method is
 called before the properties are repopulated by the controller.</p>

 <p>The default implementation does nothing. In practice, the only properties
 that need to be reset are those which represent checkboxes on a session-scoped
 form. Otherwise, properties can be given initial values where the field is
 declared. </p>

 <p>If the form is stored in session-scope so that values can be collected
 over multiple requests (a "wizard"), you must be very careful of which
 properties, if any, are reset. As mentioned, session-scope checkboxes
 must be reset to false for any page where this property is set. This is
 because the client does not submit a checkbox value when it is clear (false).
 If a session-scoped checkbox is not proactively reset, it can never be set
 to false.</p>

 <p>This method is <strong>not</strong> the appropriate place to initialize
 form value for an "update" type page (this should be done in a setup Action).
 You mainly need to worry about setting checkbox values to false; most of the
 time you can leave this method unimplemented.
