So, here’s something to keep an eye on if switching to AIR 3.8 (or 3.7 with the ASC2 compiler). Last week at work we decided to finally make the jump from AIR 3.5 to AIR 3.8; something I was pretty excited about and had been looking forward to for awhile. After applying the update, though, I noticed some unit tests failing and sat down to investigate. Several places in our app, we map loaded xml files to data objects – a pretty common thing to do.
