Dianne, Thanks. I do wonder though, would it have been possible, architecturally, to separate "showing" a fragment from "adding" a fragment to the fragment manager.
For example when I "show" a dialog fragment it does both "adding" and "showing" of that fragment. Sameway when I dismiss a dialog, it stops "showing" the fragment and also "removes" it. So I have no mechanism to retain that fragment once it is dismissed. So "state" is intimately tied to "visibility". But again I am just getting to know them and probably there are stronger reasons to tie them strongly to the UI Thanks again for your tireless support on this forum and elsewhere.
