Typing in any Text Field crashes app
<p>For some reason whenever I add a text field to my project and try type in it, the app crashes.</p>

<p>The errors I get are:</p>

<pre><code>Can't find keyplane that supports type 4 for keyboard iPhone-PortraitChoco-NumberPad; using 1336863583_PortraitChoco_iPhone-Simple-Pad_Default

-[NSNull length]: unrecognized selector sent to instance 0x1018b1d80

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSNull length]: unrecognized selector sent to instance 0x1018b1d80'
</code></pre>

<p>This happens in both the simulator and on device. I have unchecked "Connect Hardware Keyboard" in the simulator settings also. </p>

<p>Do I have to handle each and every input?</p>
