Some more thoughts about this.
I think this is a design error in struts2.


    public static ActionRequest getActionRequest() {
        if (!isEvent()) {
            throw new IllegalStateException(
                    "ActionRequest cannot be obtained in render phase");
        }
        return (ActionRequest) getContext().get(REQUEST);
    }


Code is done like this, thats ok because i should not be able to make state=
=20
changes, it seems good to not allow access if this is render phase.
However, PRG does allow transfering objects in the session (ActionErrors,=20
Messages and FieldErrors for example have to be put there to show them on t=
he=20
next action - have to be "handwritten" interceptor or something).

But the only way i see to get at the portlet global session is via the=20
ActionRequest calling getPortletSession (it is the only one, isn't it?) - b=
ut=20
if i cannot call getActionRequest, how should i get my session object?
This is confusing - implementing SessionAware does not help, because the on=
ly=20
thing i get is the session applied to my portlet, but not the global sessio=
n=20
(APP_SCOPE) i need to share stuff between portlet/servlets.
Some hints? File a jira report?
