If you're the only person working on a project, interfaces can be less useful unless you know how to use them well. Putting them in just to put them in serves no purpose other than bloating your code. But, sometimes you need to do that in order to figure them out.
I'd even go as far as saying that if you don't know what they are, you probably don't need them ;-) In your typical every day Flex/Flash type of applications they're (usually) overkill. You'll see them used in frameworks and microarchitectures, like the Flex framework, Cairngorm, etc.. So they're more of an API-thing rather than an RIA-thing (if that makes sense). Have a look at the available flex framework interfaces (they typically begin with a capital I): http://livedocs.adobe.com/flex/3/langref/all-index-I.html regards, Muzak _______________________________________________ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
