hi,

i want to put an mask animation on my MC container, and play this animation just when the picture is loaded.

```auto

if (_this._parent.conteneurFolio.xmlPict._width) {
                delete this.onEnterFrame;
                _this._parent.conteneurFolio.xmlPict.attachMovie("blocksMask", "blocksMask2", 455);
                _this._parent.conteneurFolio.xmlPict.setMask(xmlPictMsk);
                _this._parent.conteneurFolio.preloader_mc.tween(["_alpha"], [0], .4, "easeOutExpo");
                alpha(_this._parent.conteneurFolio.xmlPict, 100, 0.05);
                _this._parent.conteneurFolio.xmlPictMsk.gotoAndPlay("go");
                trace("chargement ok");

```

this is a part of the preload AS code.  
when the pict is loaded (if (\_this.\_parent.conteneurFolio.xmlPict.\_width)) i want to apply the mask.  
unfortunately, it doesn’t work…

idea ?
