<P>
<p>Specialized subclass of <code>ActionForm</code> that allows the creation of form beans with dynamic sets of properties, without requiring the developer to create a Java class for each type of form bean.</p> <p><strong>USAGE NOTE</strong> - Since Struts 1.1, the <code>reset</code> method no longer initializes property values to those specified in <code><form-property></code> elements in the Struts module configuration file. If you wish to utilize that behavior, the simplest solution is to subclass <code>DynaActionForm</code> and call the <code>initialize</code> method inside it.</p>
