Force close (NullPointerException) when changing orientation
When all that is being displayed fits on a single screen (in my case the menu and a first-level listview), changes in orientation have no problems. I get a NPE and forced close when I add a subsequent fragment and it would cause the panels to have more than a single screen's worth of fragments. The NPE is thrown when the "off screen" fragment tries to do anything on the UI thread.
This problem occurs on both a phone (Galaxy Nexus 4.1.2) and a tablet (HP TouchPad 4.0.4)
App code can be found at: https://github.com/dnsdotcom/DNSDroid
I did a pull and cleaned my projects and tried again. Still got the same result. Once I was 3 levels deep, changing the orientation still causes a force close. Thank you very much for getting back to me so quickly!!! Below you will find the relevant portions of the log:

This could be related to how AndroidAnnotations handles portioning work between the foreground and the background. It may be trying to use a widget before the activity/fragment is fully resumed/created.
Cool, I'll check this out this weekend. I'm a little bit swamped until then :P
No worries... Thanks for all of the help!

Hey! Sorry this took forever for me to get around to this. With the most recent version of the library, I tried importing your project. I added a non-sense key in the first screen.
Then, from the side-menu, I clicked Domains (loading up an initial content fragment), then the '+' button (which adds a new fragment on top of it). Seems to work fine to me.
I'll give it a shot as soon as I can. Thanks!
