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}

                 Key: RF-9368
                 URL: https://issues.jboss.org/browse/RF-9368
             Project: RichFaces
          Issue Type: Bug
      Security Level: Public(Everyone can see) 
          Components: component-a4j-core
    Affects Versions: 3.3.3.Final
            Reporter: Kai Gülzau
              Labels: a4j
             Fix For: 3.Future

 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>
 <meta id="Ajax-Response" name="Ajax-Response"
content="true" />
