I've used AS3CoreLib's JSON encoding/decoding in the past, but some code I'm maintaining now has custom JSON handling. Note: we use ISO 8601 for Dates.
Looking at the Flashbuilder 4 data wizards (briefy), I see JSON support and references to something call "fiber", but am unclear whether this is tied to LiveCycle, and whether it's Flex 4 specific. So I guess I'm wondering what the best-practice is these days for JSON support a) With Flex 3 b) With Flex 4 Thanks.
