JSF Portlet doesn't render after EventHandler

Question

I'm trying to set up basic event IPC between 2 JSF portlets in WLP 10.3.2.
Portlet A has a JSP with an inputText and and a commandLink:
<h:inputText value="#{aBean.inputValue}"/>
<h:commandLink action="#{aBean.clickMe}" value="Click Me">
</h:commandLink>Backing action creates the event:
public String clickMe() {
    FacesContext fc = FacesContext.getCurrentInstance();
    ExternalContext ec = fc.getExternalContext();
    ActionRequest ar = (ActionRequest)ec.getRequest();
    HttpServletRequest request =
        (HttpServletRequest) ar.getAttribute("javax.servlet.request");
    PortletBackingContext pbc =
        PortletBackingContext.getPortletBackingContext(request);
    pbc.fireCustomEvent("clickMe", inputValue);
    return "";
}Portlet B is configured with Init-Param:
javax.portlet.faces.bridgeEventHander=com.example.event.EventHandlerand Java Processing Event for {urn:com:oracle:wlp:netuix:event:custom}clickMe
EventHandler has:
public EventNavigationResult handleEvent(FacesContext context, Event event) {
    String elExpression = "#{bBean}";
    ELContext elContext = context.getELContext();
    ValueExpression valueExpression = context.getApplication().getExpressionFactory().createValueExpression(
        elContext, elExpression, BBean.class);
    BBean bBean = (BBean)valueExpression.getValue(elContext);
    bBean.setDisplayValue((String) event.getValue());
    return null;//new EventNavigationResult(null, "clickMe");
}It doesn't seem to matter whether or not I return an EventNavigationResult.
If I have both portlets displayed on the same portal page, portlet B is not rendered after the event processing. Only the portlet header displays.
As a workaround, I found that if I set a WLP-Handled Event to Handle Custom Event and Change Window State to normal, the portlet renders correctly. However, this workaround does not work if the portlets are on different portal pages as my usecase requires.
Am I missing something or what do I need to do to get the receiving portlet to render? Anyone have a basic JSF event IPC example working?
