Omitting A Layout
What if I don't want a Layout to be part of the Back stack?
Simple don't add the 1st repetition of the field zz.BackMagic1Text.ct to that layout. It is probably simpler, however, just to leave all the BackMagic buttons off the layout all together. This is what you'd do with pop-up windows, reports, etc. if you don't want users to go back to them.
