based on this example:
<a4j:commandButton value="Submit"
action="#{mappedAction}"
eventsQueue="#{eventsQueue}"
reRender="#{myId}noteArea"
onclick="this.disabled=true"
oncomplete="#{facesContext.maximumSeverity == null ? '' : 'this.disabled=false'}" />
I'm trying to show and hide a modal panel based on the validation
<a4j:commandButton value="Submit"
action="#{mappedAction}"
eventsQueue="#{eventsQueue}"
reRender="#{myId}noteArea"
oncomplete="#{facesContext.maximumSeverity == null ? '' : rich:component(modalConvalida).hide()}"
onclick="#{rich:component(modalConvalida)}.show()"
/>
Where modalConvalida is a ui:param passed into my facelet composite component, but I can't manage to get the syntax right. the panel shows onclick, but it doesn't get hidden in the oncomplete.
If I put an alert in the second branch of the ? operator I can see that it gets executed, though.
