I have a Portal 2.7.0GA implementation. When playing around with the default site I changed, when logged in as admin, the preferences of the google weather portlet on the samples page to 4904pp. This caused an inalid index exception and I was not able to re-enter portlet edit mode to get rid of the wrong zipcode.
Looking further I could not find any possibility to update the user preference value of that portletinstance. This also not in the admin portal.
Only by directly updating in the jboss database I was able to get a working situation for the admin user again.
Is there a way using the admin portal to change/remove user preferences for a portlet ?
I am still struggling with this.
Is there a way that I can access the user preferences by code so I can write a portlet to change/remove these ?
If not, is the datamodel described so I can try to access the database directly to remove the prefs
