Out of the box when using deferred instantiation the ViewStack was designed to only support animations on a child container 'hide' not 'show'.
If you only slide 'out' it should work fine, if you want to slide 'in' or both 'in' and 'out' you need to roll you own version of ViewStack and build in the support. This is something we have done, though I can't really help with the code because of copyright. You need to override selectedIndex, commitSelectedIndex, and commitProperties as well as add a function to init the selected child container. Its not really difficult, you should take a look at the adobe code in the ViewStack and basically emulate that. --- In [email protected], Alex Harui <aha...@...> wrote: > > I still believe that all children of a viewstack are created no matter the > creationpolicy.
