SearchBar in Navigation Bar not working

问题

For reference, I'm running the below on an iPad with iOS 7.0.4. The vc is a presented modally as a form page. The search vc is the second vc on the navigation stack.

My table is setup with a search bar and search display controller and is working fine with the search bar located in the header of the table. It returns search results just fine...see image:

I make a one line code change in the vc's viewdidload method to move the search bar to the navigation bar:

searchDisplayController.displaysSearchBarInNavigationBar = YES;

and, while the search continues to work (I can see the search results build via the console) the search results table never updates and I end up with this:

I am at a complete loss on this one. I can't see where I'm going wrong...please help!!!

thanks
