After struggling with it for a day, this is what i found.

I am using ListFragment and Loaders with support library.

If I used same/standard Loaders code in a normal Activity it ListView
maintains its scroll position very precisely.

If I am using same/standar Loaders code in ListFragment then if I scroll
position is complete lost afte orientation change. And it ListView is
scrolled to top.

I also noticed that 'savedInstanceState' is coming as 'null' to for
'onCreate', 'onViewCreated' and 'onActivityCreated', even though I am
saving some state in 'onSaveInstanceState'.

Attached is the code for fragment.

I am just wondering...am I alone..:-/...?

I found the soln. Just have to specify the 'id' field in the layout xml
file and it works fine.

Looking at soln now seems small and silly but why ADT does not create ids
for fragments by default like it does for others. Specially when it leads
to un-desirable results.
