When I try to open the modelPanel, it says "Richfaces not defined".
<a4j:commandLink id="addVC"
oncomplete="Richfaces.showModalPanel('editVcMp',{width:450, top:200})"
rerender="vcTable">
<h:outputText value="#{bundle.Add}"/>
</a4j:commandLink>
figured it out, the modalPanel tag is not added to the page correctly.
