    [ https://issues.jboss.org/browse/RF-9368?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12769933#comment-12769933 ] 

Peter Gwiazda commented on RF-9368:
-----------------------------------

org.ajax4jsf.renderkit.AjaxContainerRenderer 
{noformat}
    127		AjaxRendererUtils.encodeAreas(context, component);
    128		AjaxRendererUtils.encodeAjaxEnd(context, component);
{noformat}
then inside AjaxRendererUtils.encodeAjaxEnd the AjaxRendererUtils.encodeAreas is called once again: 
{noformat}
    964 	public static void encodeAjaxEnd(FacesContext context, UIComponent component)
    965 			throws IOException {
    966 		// AjaxContainer ajax = (AjaxContainer) component;
    967 		ResponseWriter out = context.getResponseWriter();
    968 		// DebugUtils.traceView("ViewRoot in AJAX Page encode begin");
    969 
    970 		encodeAreas(context, component);
    971 			out.endElement("body");
    972 			out.endElement("html");
    973 	}
{noformat}

> While debugging network traffic in a richfaces application i recognized some duplicate data in the XML response.
> For example all responses on the demo site for a4j:poll (http://livedemo.exadel.com/richfaces-demo/richfaces/poll.jsf)
> are containing something like this:
> ...
> <meta name="Ajax-Update-Ids" content="j_id353:poll,j_id354:grid" />
> <span id="ajax-view-state"><input type="hidden" name="javax.faces.ViewState" id="javax.faces.ViewState" value="j_id2" /></span>
> <meta id="Ajax-Response" name="Ajax-Response" content="true" />
> <meta name="Ajax-Update-Ids" content="j_id353:poll,j_id354:grid" />
> <span id="ajax-view-state"><input type="hidden" name="javax.faces.ViewState" id="javax.faces.ViewState" value="j_id2" /></span>
