liferay JSF portlet + orbeon-embeddable=true

Hi all,

I have a problem with submitting xforms (xforms:submission method="post" replace="all" action="/views/nextPage.xhtml"). Orbeon is running in the embeddable mode in a liferay JSF portlet. When I click submit button I cannot go to next JSF page in portlet, I gets an error:

orbeon error:

This solution works in typical web app (JSF + orbeon embeddable mode), but not in portlet. Does anyone know why?

We don't know much about JSF and nothing about the Liferay Faces Bridge, so I fear that we cannot help much.
