CheckGroupSelector problem

[atul singh]

I am facing an issue with CheckGroupSelector.
CheckGroupSelector is not showing itself selected, though all of the Check's
in the CheckGroup come pre-selected based on the underlying model i am
setting up. (That means I have the CheckGroup's list model already populated
with all individual Check's models).
Is this because CheckGroupSelector does not have a model for itself?
OR am I missing something???
