<p>This page demonstrates Click's support for multiple forms on the same page.</p>

<p>To see how this works, enter and submit a name in either form1 or form2. 
Notice that the value you entered are displayed in the name field after the 
submit.</p>

<p>Now click the 'Refresh/Reload' button on your browser. A confirmation dialog
should popup warning you about the dangers of resending form data. Click
'Retry/OK' to continue. At this point Click will receive your second POST, and
notice it is a duplicate.</>

<p>Because it is a duplicate POST, the request is not processed further and you
will be redirected back to this page. An error message will also be displayed.</p>

<p>For more information on duplicate POSTs please read the section 
<em>"Preventing Accidental Form Posts"</em>
<a target="_blank" href="http://incubator.apache.org/click/docs/click-api/org/apache/click/control/Form.html">
in the Form's JavaDoc.</a></p> 

<p>Also look at the
<a target="_blank" href="$context/source-viewer.htm?filename=WEB-INF/classes/org/apache/click/examples/page/form/MultipleFormsDemo.java">Java Source</a>
to see how this example is implemented.</p>
