Classic motion tween within movie clip is not playing

[jodellingjoe]

I´ve created a clip of a bubble as a movie clip that should burst once put on stage. The bursting animation within the bubble clip is created as classic tween and should play once but is not performing at all. I did export the clip as asset, where the bursting animation is shown in the thumb of the asset. But on stage it does not perform neither. Whats wrong?

Found the problem: the tween has to be inside of a graphic clip not a movie clip - that has been different in Flash times...
So it worked, when I created a graphic instance and copied the tween frames into it.
