Its very rarely I use Repeaters. I always thought of them as a way to get a list of items on the screen, yet they would always create all the items, therefore not being as optimized as a List that only creates just enough renderers, and re-uses them.
Recently on a job I required the children of a ViewStack to be driven by a dataProvider. The ViewStack required the same number of children as the number of items in the dataProvider. Each child should use its corresponding item in the dataprovdier to render its content, set via the data property.
I knew this could be handled with ActionScript, but ideally wanted a component that took care of it internally. To achieve this I built something called a DataStack, that had a dataProvider property. This worked fine but a couple of days later when building a custom container for tiling items I realized I’d been wasting my time, and a Repeater inside a ViewStack would have done the job I wanted.
What a donkey I am sometimes!
For good measure in the this example I added one of the new Efflex effects.
