So, even with my above null guards, odds are this proxy object will stop functioning after changing themes. The root issue is that the module's proxy objects are wrongly being released when the activity is being recreated, but I'm not seeing this issue anywhere else (such as MapView in \"ti.map\"). I can't get to the root of the issue without seeing the module's code.",
