Repeater is much more flexible than many people think. It is often thought of as a way to make a list, but is really more a dataProvider driven wrapper for addChild and removeChild, with a few other cool things built in.
I can imagine several use cases for needing to reference a repeated item. I have done it myself, though if I were to reproduce today the particular functionality I am thinking of, I would use events instead.

All of the items I have in a repeater are instances of a specific object. This object has class members and functions and can do everything it needs to do on its own. If I need it to (Which is infrequent) each object can get to its parent or even the Application object itself. So, I ask, Why would you need to refer to a repeated component? --- In flexcoders@yahoogroups.com <mailto:flexcoders%40yahoogroups.com> , "Amy" <[EMAIL PROTECTED]> wrote: > > --- In flexcoders@yahoogroups.com <mailto:flexcoders%40yahoogroups.com> , "sdl1326" <azsl1326-email@> wrote: > > > > I am using the Tile Component along with a repeater and then a custom > > component (image control).
