I am trying to show multiple controls in my start facet :
<a4j:status> <f:facet name="start"> <h:graphicImage value="../images/indicator_circle_ball.gif" /> <h:outputText value="processing ..." /> </f:facet> <f:facet name="stop"><h:graphicImage value="../images/spacer.gif" /></f:facet> </a4j:status>
java.lang.IllegalStateException: facet 'start' already has a child associated. current associated component id: configListForm:_idJsp3 class: javax.faces.component.html.HtmlGraphicImage at javax.faces.webapp.UIComponentTag.findComponent(UIComponentTag.java:560)
facet should ha?? only one child component - so if you need to have multiple components inside - around the with h:panelGroup for example.
