To my understanding (and I am a newbie):
1. All callbacks are valued before rendering components
2. Callback processing is not done if a high priority callback cancels further 
processing via `self handleAnswer: false`.
3. Callback processing is also cancelled by #respond processing.
The WACancelButtonTag is set to high priority (-5). In my opinion you can cancel 
further processing of callbacks (and validation) by setting 
`self handleAnswer: false.`.
Watch out if you also have AJAX as to my understanding also has priority -5.
