Not sure about a way with portlets, but this should work with a servlet
environment:
"POST".equals(((HttpServletRequest)FacesContext.getCurrentInstance().getExternalContext().getRequest()).getMethod())
Note that all command* components post, so this will not tell you if the
page is new or not.
Another way is to store an attribute in the UIViewRoot during rendering. If
it is present, it is the 2nd (or more) time that the page has been renderer,
and if it is not set then it is the first.
FacesContext.getCurrentInstance().getViewRoot().getAttributes().get("myproperty")
!= null
...
FacesContext.getCurrentInstance().getViewRoot().getAttributes().put("myproperty",
true)
