IPhone keyboard stops appearing

Question

I have an issue with the keyboard not responding.
Use a UINavigationViewcontroller and have your drill-down page contain a UIScrollView with a UITextView as the subview. If you drill down and click to get the keyboard, you'll never be able to drill down again and get the keyboard.
Here's the repro steps (sorry if the formatting is bad):
1) Start with the SimpleDrillDown app.
2) Create a new UIViewController call "TestViewController"
3) replace creation of the DetailViewController in MasterViewController.m with the TestViewController:
testViewController = [[TestViewController alloc] init];
4) Create a UIScrollView as the TestViewController view and add a UITextView as the subview of the UIScrollView:
UIView *view = [[UIScrollView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];
view.autoresizingMask = UIViewAutoresizingFlexibleHeight|UIViewAutoresizingFlexibleWidth;
self.view = view;
UITextView* tv = [[UITextView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];
[view addSubview:tv];
[tv release];
[view release];
The first time you drill down to UITestView and click, you'll get a keyboard, but when you go back and drill down again you get no keyboard.
Any ideas?

I did notice this and fortunately it does NOT appear to be an issue with the keyboard, but rather with the master controller.
You can repro this without clicking the edit button on a detail view. The issue seems to be caused by the fact that going from a detail view back to the master view does not clear the selected item from the master view, so it's not actually possible to select the item you already had selected.
The solution is shown in the SimpleDrillDown sample I think. I believe in that sample they show how in the master view controller you can focus the table-based master control on the top entry in its table and deselect all table items.
As far as the Edit button on the main view...I've never tried it so far, but I'll be getting to that point in my app shortly.
