Ive looked at the source and it seems to want to get the org.apache.myfaces.SERIAL_FACTORY from the context, whitch is not there for some reason. Any-one has any ideas?

+1  A: 

Just a guess (I have not tried this out), but it does appear to be a similar stack trace, as well as a code fix of exporting SERIAL_FACTORY as an Attribute:

http://wiki.apache.org/myfaces/PortletSerialFactoryWorkaround

Here is the exception they specify:

java.lang.NullPointerException: serialFactory
        at org.apache.myfaces.shared_impl.util.StateUtils.getAsByteArray(StateUtils.java:174)
        at org.apache.myfaces.shared_impl.util.StateUtils.construct(StateUtils.java:150)
        at org.apache.myfaces.renderkit.html.HtmlResponseStateManager.writeState(HtmlResponseStateMa
nager.java:73)
        at org.apache.myfaces.application.jsp.JspStateManagerImpl.writeState(JspStateManagerImpl.jav
a:430)

And, the fix they recommend: "To work around this problem, extend MyFacesGenericPortlet and override the init() method as follows:"

public void init() throws PortletException, UnavailableException
{
   super.init();
   getPortletContext().setAttribute("org.apache.myfaces.SERIAL_FACTORY", new org.apache.myfaces.shared_impl.util.serial.DefaultSerialFactory()); 
}
