I don't know what's causing your problem. I'd need more info like which Domino version, which mobile controls version, which elements you copied, which browser, etc.
The easiest way is to simply use MobileControlsLite.nsf and point it to your existing nsf, e.g. in the mView control and the document control.
If you want to copy the design elements I'd copy the elements from MobileControlsLite.nsf rather than downloading it from Dojo. You can find the Dojo files and my JavaScript files in certain subfolders like 'dojocustom'. In order to do this you need to use the Package Explorer view or Java perspective. But again, this is harder since I haven't had the time to document this.
