Most flaming weapons do have to be activated though, but I suppose if you activated your flaming weapon, then got hit with an AMF, it would start flaming again once outside the AMF. That's kind of an interesting edge case, but I'd probably allow it if I were running the game.
Again though, the general rule is that both the source and target of the entire magic effect must be outside of the AMF for it to work. Any magic effect that requires activation makes the activating party part of the "source" of the magic. Any effect that affects a persons abilities in any way makes that person part of the "target" for the effect (so things like AC boosts, to-hit boosts, etc only work if the target is not in the AMF).
