Ajax response without the structure of XHTML

neeryck Jul 24, 2010 7:08 PM

Hi,

My page have the following code:

...........
<a4j:region id="region" renderRegionOnly="true" > 
                    <a4j:poll reRender="colum" action="#{bean.test}" interval="1000"/>
 
<rich:dataTable value="#{bean.list}"
                                    var="list" 
                                    id="dataTable" 
                                    rows="10"
                                    ajaxKeys="#{bean.keyToUpdate}">
 
                        <rich:column id="colum">
                            <f:facet name="header">
                                <h:outputText value="Name" />  
                            </f:facet>
                            <h:outputText id="name" value="#{list.name}" />
                        </rich:column>
     ............

The code snippet above do update only the row I want through ajaxKeys. But looking at wireshark(http://www.wireshark.org/) the app receive all XHTML's structure from ajax request! In other words, it send 1150 bytes (depending of update's information) of 1500 total bytes of an IP packet.

Can I send only the information (without XHTML structure) and uptade the dataTable's row?? And if I can't, I wanted to understand why.

Thank's in advance!!

define name in reRender instead of column.

Thank's for reply Ilya !
This text is the least that can be generated by an ajax response??
The some values send on response are duplicate!

<?xml version="1.0"?>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
</head>
<body>
<span style="display:none;" id="form1:j_id63">
<script type="text/javascript">//<![CDATA[
A4J.AJAX.Poll('form1',{'pollId':'form1:j_id63','similarityGroupingId':'form1:j_id63','parameters':{'form1:j_id63':'form1:j_id63'} ,'pollinterval':1000,'containerId':'form1:j_id62'} );
//
//]]>
</script>
</span>
    <span id="form1:dataTable:0:name1">5400438</span>
    <meta name="Ajax-Update-Ids" content="form1:j_id63,form1:dataTable:0:name1" />
    <meta id="Ajax-Response" name="Ajax-Response" content="true" />
    <span id="ajax-view-state">
    <input type="hidden" name="javax.faces.ViewState" id="javax.faces.ViewState" value="4df2fXcsdZJfbc+/w9DZTgh4QLcb2FPRLXtvNq3V2OkyJBT3C1AB4cuAGr7a+EmF3NDY6k/gqKSHNa6wP512VDS3suMdX2GzlL+DdW2tSSEqupn2OciykA==" /></span>
    <meta id="Ajax-Response" name="Ajax-Response" content="true" />
    <meta name="Ajax-Update-Ids" content="form1:j_id63,form1:dataTable:0:nome1" />
    <span id="ajax-view-state">
    <input type="hidden" name="javax.faces.ViewState" id="javax.faces.ViewState" value="4df2fXcsdZJfbc+/w9DZTgh4QLcb2FPRLXtvNq3V2OkyJBT3C1AB4cuAGr7a+EmF3NDY6k/gqKSHNa6wP512VDS3suMdX2GzlL+DdW2tSSEqupn2OciykA==" />
    </span>
</body>
</html>

Just out of curiosity... why it's duplicated? This is the issue!
Thank's in Advance!
