Hi, I have a very simple reRender problem
Here is a snippet of my code:
...
 <a:region>
 <a:log hotkey="Q"/>
 <a:form>
 <h:graphicImage value="/images/printer.png" />
 <a:commandLink reRender="printout1">
 <h:outputText value="drukuj" />
 <a:actionparam name="id" value="#{jobparam.id}" assignTo="#{printJob.jobToPrint}"/>
 </a:commandLink>
 </a:form>
 <a:outputPanel id="printout1">
 Y#{printJob.jobToPrint}Y
 </a:outputPanel>
 </a:region>
...
1) Regions - not allowed in side dataTables
2) if you need to reRender only the current row in the table - you should use org.ajax4jsf.ajax.ForceRender ajax Listener.
