No idea what you mean. I have no idea why you'd want to set a field which keeps information whether a particular widget has focus or not.
I have the first wizard page: WP1
- with the fist button u go to WP2
- with the second button u go to WP3

this are 2 diferent ways of pages but both go to WPEnd.
Then in WPEnd I need to know if user arrived there throw WP2 way or throw WP3 way and that is what I am trying to do: a way to know that.
