[]骨骼动画销毁后再创建，报错

调用下面代码，销毁骨骼动画和它的模板后
skeleton.player.templet.destroy();
Skeleton.destroy();
 
再调用下面代码，新建模板并且创建骨骼
var sk:Skeleton=new Skeleton();
var templet:Templet = new Templet();
templet.parseData(texture, arrbuffer, 20);
sk.init(templet);
 
然后报错
 Cannot read property 'enableMerageInAtlas' of null
