Do you know of any way to do this if the underlying DataModel is in a property of a request scoped bean and the you couldn't use preserveDataModel="true", t:saveState, or any other things beyond the spec itself ? I am in such a situation and the only solution I see at this time is using f:param in the JSP and server side manual request parsing.
