[flexcoders] Differences between itemUpdated and setItemAt for ArrayCollections

[j_lentzz]

Hi,

I have a general question about when to use the two methods
itemUpdated and setItemAt on ArrayCollections.

if you use obj = getItemAt(someIndex) and then change some properties
in the obj, what difference is there between using
setItemAt(obj,someIndex) or using itemUpdated(obj)?  Is there a
particular reason to choose one over the other?

Thanks,

John
