Problems with MyFacesGenericPortlet and WSRP

Hi,

using MyFacesGenericPortlet to convert a JSF application into a
portlet works great. However, there are some problems if a JSF portlet
is exposed through WSRP. I'm using Liferay 4.2.2 as WSRP producer
which contains an implementation of WSRP4J to expose portlets.

1. Resource URLs (e.g. images) are not correctly encoded. The
resources are referenced with relative URLs so the consumer is not
able to retrieve them.
2. As soon as I use an <h:form>...</h:form> element, the portlet is
not rendered anymore due to an exception:

Caused by: org.apache.jasper.JasperException: Exception in JSP:
/jsp/index.jsp:11
8: <body>
9: <f:view>
10:
11:     <h:form>
12:       <h:panelGrid cellspacing="15" id="imageTable" columns="2">
13:          <h:outputLabel style="font-size:medium" value="#{msg.image}" />
14:          <h:graphicImage url="/images/jsf.gif" />

I'm not an expert of the MyFaces implementation, so I don't really
understand why the h:form element causes such a problem. Maybe someone
has already experienced similar issues.

Has anyone successfully consumed JSF Portlets through WSRP? If yes
which implementation did you use for producer and consumer.

Kevin
