ActionBarSherlock NAVIGATION_MODE_LIST doesn't work with ViewPagerIndicator

view story

http://stackoverflow.com – I'm creating a news App where user can choose the source site Via a drop down (list navigation) in the ActionBarSherlock then the categories of the selected site are displayed in ViewPager with a ViewPagerIndicator. Now the problem is that the list navigation in ActionBarSherlock doesn't do anything when I tap on it as if it's not triggering the onclick even on the spinner. But When I remove the ViewPagerInidcator it works fine. Is there a conflict between ViewPagerIndicator and Navigation Mode in ABS ? I tried also Navigation Mode Tabs and it didn't display any tab also I triend Navigait (HowTos)
