> I'm using a4j:include navigation and the navigation is working fine as long as I'm not trying to access a page containing a rich:dataGrid component.
> The starting page is the one containing the dataGrid and is shown correctly. I have a commandLink pointing to another page, and a back button on that second page.
> When using the back button, thus retrieving the dataGrid page through Ajax, I'm getting the following error: 
> error[9:04:56,090]: Error parsing XML
> error[9:04:56,091]: Parse Error: XML Parsing Error: undefined entity Location: http://xxx/index.jsf Line Number 105, Column 61: </div></div></td><td class="dr-table-cell rich-table-cell ">&nbsp;</td></tr></tbody></table></div></div></td></tr></table></td><td id="__serviceordering_WAR_genesisjsf_INSTANCE_g8sA_:_viewRoot:j_id9:j_id10:j_id190" style="display: none;;height:100%"><table border="0" cellpadding="10" cellspacing="0" class="dr-tbpnl-cntnt-pstn rich-tabpanel-content-position" width="100%"><tr><td class="dr-tbpnl-cntnt rich-tabpanel-content " style="; "><div class="dr-tree rich-tree " id="__serviceordering_WAR_genesisjsf_INSTANCE_g8sA_:_viewRoot:j_id9:j_id10:me ------------------------------------------------------------^
> It looks like the &nbsp; (which is inserted inside an empty cell) is causing this, because if the size of the collection used to populate the dataGrid is a multiple of the dataGrid number of columns, everything is working fine.
> Here's how to reproduce:
> index.xhtml
> 		<a4j:form>
> 			<a4j:include
> 				viewId="page1.xhtml" />
> 		</a4j:form>
> page1.xhtml
> 		<a4j:commandLink action="#{myBean.toSecondPage}"
> 			value="Go" immediate="true" />
> page2.xhtml
> 	<rich:dataGrid value="#{myBean.elements}" var="element" 
> 						columns="3">
> 			<rich:panel><h:outputText value="#{element.id}" /></rich:panel>
> 	</rich:dataGrid>
> and having the myBean.elements collection having less than 3 elements.
