FragmentPagerAdapter adapter =
(FragmentPagerAdapter)mViewPager.getAdapter();
Fragment fr = adapter.getItem(
mViewPager.getCurrentItem() );
What do i need to do?

Problem is getting to the Fragment object itself - can't get it unless I
store references in my Activity.
I'm sub-classing FragmentPagerAdapter for my adapter...
and just came across getItemId() which lets you set an id as the fragments
are created by the adapter.
i would have thought that then fragmentManager.findFragmentById() would
have worked.
I've verified the getItemid() method is being called.
but still no go.
