Can a4j:poll update just a component within column of rich:d

[hgk]

Hi all,

I have a4j:poll that updates a component within the column of rich:dataTable. See the code below.

I am not not sure if it is actually updating the entire table or just the component within the column. I don't want the entire table to refresh. With the code below, looks like entire table is getting refreshed.

Thanks,
hgk

<rich:dataTable ....>
....
<rich:column id="statusColumn" headerClass="managerSectionHeader">
<f:facet name="header">
....
</f:facet>
<h:panelGroup id="statusGroup">
<h:graphicImage url="/images/loading_blue_small.gif" rendered="#{discoveryTask.running}"/>
</h:panelGroup>
</rich:column>
</rich:dataTable>

<a4j:region>
<h:form>
<a4j:poll id="refreshStatus" action="#{FileServerListPage.updateStatus}" reRender="statusGroup"
timeout="50000" interval="1000"/>
</h:form>
</a4j:region>
