Are there limitations on what can go on camera overlay?

[mpemburn]

Hi,

I'm working on an app for iPad that uses the video camera and having trouble getting the controls I want to appear or work on the overlay. The controls should be a Pause/Resume button on the left with a label indicating the run time; a Start/Stop button in the middle and a Cancel button on the right. The Pause/Resume appears and does process taps, as does the Start/Stop. The time label is not visible at all and the Cancel button doesn't send the event to the listener, even though it appears to be responding when you tap it. Any ideas?

BTW: I'm developing this with Appcelerator Titanium and it's not unlikely that the problem is with their implementation. I'd ask a question on their Q&A but it could be months before someone answers.
