  FACES-237	Bug in processing of public render parameters
  FACES-1453	PortletContainer.maintainRenderParameters clobbers existing public render parameter values
  FACES-1551	BridgePublicRenderParameterHandler.processUpdates() gets called even if the public render parameters did not change
  FACES-208	Public Render Parameters not working bi-directionally with Liferay 5.2.3
  FACES-1428	XSD validation failure due to missing namespace in liferay-faces-bridge-2.0-extension.xsd

The jsf2-ipc-pub-render-params-portlet demo has a WEB-INF/faces-config.xml descriptor that looks like this:

<bridge:public-parameter-mappings>
	<bridge:public-parameter-mapping>
		<parameter>selectedCustomerId</parameter>
		<model-el>#{customersPortlet:customersModelBean.selectedCustomerId}</model-el>
		<model-el>#{bookingsPortlet:bookingsModelBean.selectedCustomerId}</model-el>
	</bridge:public-parameter-mapping>
</bridge:public-parameter-mappings>

But Section 5.3.1 of the Spec titled "Configuring a Public Render Parameter Mapping" indicates that instead, it should look like this:

<bridge:public-parameter-mappings>
	<bridge:public-parameter-mapping>
		<parameter>customersPortlet:selectedCustomerId</parameter>
		<model-el>#{customersModelBean.selectedCustomerId}</model-el>
	</bridge:public-parameter-mapping>
	<bridge:public-parameter-mapping>
		<parameter>bookingsPortlet:selectedCustomerId</parameter>
		<model-el>#{bookingsModelBean.selectedCustomerId}</model-el>
	</bridge:public-parameter-mapping>
</bridge:public-parameter-mappings>

In summary, the namespace prefix should be specified in the <parameter> element rather than the <model-el> element. This will require not just a fix to the WEB-INF/faces-config.xml descriptor, but also to the bridge.
