[gatein-issues] [JBoss JIRA] (GTNPORTAL-1987) PortletPreferences.store() has no effect in a serveResource

donino doninos commented on GTNPORTAL-1987:
-------------------------------------------

That's pretty strange, gatein will be the only J2EE portal where we can't update preferences through serveResource. Both Jahia, Websphere, Liferay and even Apache Pluto support this key feature. The full page refresh on each action request is prohibitive for many kind of portlets. Difficult to understand but you probably have good reasons.

> Portlet method "serveResource" method is fired when ajax requests a resource. 
> A code as below works in "processAction" method, but in serveResource PortletPreferences.store() statement doesnt seem has any effect: preferences are not stored in database.  
> String mypreference= request.getParameter("mypreference");
> PortletPreferences portletPreference = request.getPreferences();
> portletPreference.setValue("mypreference", mypreference);
> portletPreference.store();
> Specifications 286 authorize update preferences in serveResource method (PLT.13.1):
> "For serveResource calls only state changes to non-shared state, like the portlet session scope or portlet preferences, should be performed"
