Description
This error occurs randomly often throughout our app and every user who has updated to the latest iOS is reporting crashes. Any suggestions on how I may be able to track this down or what is causing it. Here is the exception thrown just before the crash:
*** Terminating app due to uncaught exception 'org.appcelerator.TiUIViewProxy', reason: 'Value was not the value expected'
*** First throw call stack:

The error suggests that a child view is not actually part of the parent view anymore. Likely something is wrong with your view hierarchy and has now been causing issues with newer iOS versions.
I see. Thank you for the hint.
[~jerodfritz] Did you try the [~hknoechel] suggestion? Please let us know with some reproducible test cases if you still having this issue. Thanks!
Thank you for checking in. You can close this. It took some digging but ultimately Hans was correct. I was trying to alter a textfield while it was not part of the view hierarchy.
