Hi everybody,

I'm quit confused. I use a normal commandLink within a dataTable but during the rendering of the side I get the following error:

java.lang.RuntimeException: wrapped Exception: java.lang.NullPointerException
at com.icesoft.faces.webapp.http.servlet.MainServlet.service(MainServlet.java:156)

)

As soon as I remove the f:param attribute I don't get any error!

This is the code which occurs the problem:

Code:

 <ice:dataTable 	value="#{bean.values}" var="item" styleClass="maxWidth" columnClasses="width70,width30">
 		
 			<ice:column>
 				<ice:commandLink actionListener="#{bean.showDetails}" value="Details">
 					<f:param id="itemId" value="#{item.internalId}" />
 				</ice:commandLink>
 			</ice:column>
 		
 		</ice:dataTable>

Any ideas?

Thanks in advance!

Sometimes I'm blind!

Would be better to use "name" instead "id" ;)
