Hi, I have a fragment that contains a linearlayout with a bunch of controls to make an edit form (edittexts, spinners, buttons, etc). We have a "review" button that replaces that fragment with a view form (again a linearlayout, but with textviews only) and this transition gets added to the back stack (so the user can change something if they entered a wrong value).
This is all hosted within the same activity. I create the first fragment in code and call FragmentTransaction.replace() on the container view. Both fragments dynamically create their content in onCreateView(). This is also when the Spinner adapters get created. This all works fine, except that if I press the back button, the app crashes (apparently trying to restore the instance state of a spinner). I don't think I'm doing anything wrong (my code isn't even in the stack trace, and this happens before onCreate). Logcat is below.
