Hi all,
Quick one, I think. :)
I have two Components in my application, based on a ViewStack. For the
purpose of simplicity, let's call them AdminView and UserView.
Essentially the two ViewStacks contain different screens (or the same
if applicable) dependent on the access level returned from
branch and leaf has a checkbox on it (think MSBackup,
for example). Any ideas for that?
