It definitely is some sort of race condition but the thing that is confusing me is the fact that it's reporting that the selected index and the selected child are those that I'm expecting but the display is wrong. I've tried adding a validateNow() call before the change but that hasn't made much difference.
I'm gonna have to look at my code to figure out a better way for me to control when this is called, but it really doesn't make much sense to me why the viewstack is reporting that it's got everything selected as expected but no matter how much I try to force it to update (by calling validateNow or invalidateDisplayList etc.) it doesn't seem to want to show the correct selected index the first time after the component is loaded. -D --- In flexcoders@yahoogroups.com, "Alex Harui" <[EMAIL PROTECTED]> wrote: > > Sounds like timing.
