Hello, I did nothing special. As I said, I installed JBoss Portal from SVN (trunk) and I use a MYSQL database as datasource. I deployed with "build deploy" and after that I installed add-on (samples, admin, management portlets). If I log in as admin and try to change the theme of the default portal, the drop-down list switches back to default theme and the theme is not changed (but there is no error message, the theme simply does not change). The same thing happens if I create a new user with admin role. The only theme I can change is the theme of my dashboard. Thank you for your help!
