This causes a javascript error: "Cannot call method 'show' of undefined"

The following seems to work with the workaround:
{code} 
<ui:param name="editModalName" value="editMarginModal${tableId}" />
<a4j:commandButton id="issueButton"
    onclick="alert('tableId is: editMarginModal${tableId}');"
    oncomplete="#{rich:component(editModalName)}.show()"
    action="#{richBean.helloWorld(margin)}"
    image="img/iconEdit.png" 
    render="editMarginModal${tableId}">
</a4j:commandButton>
{code} 
Is there a proper way using RichFaces.$ without having to define the ui:param?
