++++attachMovie复制多个元件问题奇怪问题+++++++
用attachMovie复制多个元件,刚开始加载加载时,通过一个循环,可以顺立复制多个MC,
但当加载完毕后,通过按纽再动态复制时,只能复制一个元件,不能复制多个,每次复制时,原先attachMovie的元件被替换了.

此代码在时间轴上初始加载时运行,可以成功attachMovie多个元件:
for (var i = 0; i <counts; i++) {
var tmp_mc = _root.attachMovie( "objcontainer ", "obj2 "+i, this.getNextHighestDepth());
//初始化
tmp_mc.img = childnodes[i].firstChild.firstChild.nodeValue;
tmp_mc._x = childnodes[i].firstChild.nextSibling.attributes.x;
tmp_mc._y =
....
}

此代码按纽点击时触发的函数,原来想每次点击几下,复制几个元件,但运行时只能attachMovie出一个元件,原来点击attachMovie出来的元件被替换,而不是重新attachMovie出一个新的元件.
_global.addObject = function(img:String):Void {

counts++;
var tmp_mc = _root.attachMovie( "objcontainer ", "obj2 "+counts, depth);
//初始化
tmp_mc.img = img;
tmp_mc._x = Math.random()*550;
tmp_mc._y = Math.random()*350;
...

};

[解决办法]
var tmp_mc = _root.attachMovie( "objcontainer ", "obj2 "+counts, ++depth);
