My FragmentActivity contains ViewPager with some pages. Once one page is modified, others need to receive notification. 
So my steps:
1. Send notification from fragment to activity
2. Getting list of fragments
3. Call notify to each one.

The problem is in step 2, to get fragments. 
Calling adapter.getItem(int i) calls MyFragmentAdapter.getItem(int i), which returns new Fragment, that is not attached to activity.

Any ideas?
