In a portlet, when you make an AJAX call to your servlet (not portlet class)
, you are unable to save user preferences to the database.  While I can mana
ged to make a portlet form request to processAction () method, the user pref
erence then get stored in d
atabase, however, the portal page will get rendered (re-flashed) again.

So, the problem:  how to make an AJAX call and save the user preferences, wh
ile the portal page will not get re-flashed?

Thanks
