I've seen it a long time ago, and I can't believe is NOT fixed yet. 4th, August, 2010!! Flash CS5 with AS3.
shame on Adobe.

Ian, not all animator know how to script and some complex animation is not so suitable to script.

Wouldnt it be better just to step into the 21st century and start using code based animation like everyone else?

You just saved me 3 hours of messing around with no avail in flash. Thanks for posting this bug and more importantly, the workaround. You rock.

hi!

that solution using a graphic did not work for me.

I put my mask keyframes inside a graphic, set it to play once and made it a mask layer. the actions inside my masked movieclips still fired their code during each keyframe change within my mask graphic.

anyone find a true solution?

You absolute legend! I've been searching for a solution to this for aaaages (it took me this long to realise that the problem was related to keyframes) – your workaround worked first try. Thanks!

I know this was posted in Octobver, but I found it interesting enought to merit a post.
Maybe I'm missing something obvious, but couldn't a compromise be to convert the mask into a graphic and set it to 'Play Once'. In that regard it won't cause the constructor to be called multiple times, and the animators can view their mask through the timeline rather than waiting to publish?

setMask() avoids the bug exactly how I outlined since it requires that you make your mask into a MovieClip. At that point, though, you're just dodging the issue and the animator still can't preview their work.

Agreed, it is a ridiculous bug to still exist, and although both these solutions will work, they don't allow for the use of the mask as you would want it.

The point of using graphics and timelines for animators is to perfectly sync timelines – 2 MovieClips cannot be expected to stay together over any period of time.

Personally, I'd go so far as to use Fuse to control both the timelines in the MovieClips – more code, more hassle, it should just work.

Another work-around solution is to use SetMask()
