iPhone keyboard ignores second request for Numeric and Punctuation

Question

I have a method that creates a local textfield and pops up the keyboard ( of a given type ) to fill the field. I call this 4 times each following the input done event of the previous.

The first time i call it with the default keyboard and the following three are with the UIKeyBoardTypeNumbersAndPunctuation keyboard. The weird thing is that the third call ( second of UIKeyBoardTypeNumbersAndPunctuation ) brings up the Default keyboard and the fourth brings up UIKeyBoardTypeNumbersAndPunctuation again.

Any ideas as to why this might be happening?

Seems like Crufy's answer to this question also solves this problem: http://stackoverflow.com/questions/1214311/becomefirstresponder-doesnt-respect-keyboard-settings

Returning NO from

- (BOOL)textFieldShouldReturn:(UITextField*)textField  

in the delegate fixes it.
