插件Glist问题

const itemRenderer: FairyGUI.ListItemRenderer = ( index: number, obj: FairyGUI.GObject )=>{
                if (obj instanceof ListItem) {
                    obj.data = this._array && this._array[index];
                    obj.setIndex(index);
                }
            }
            this.list.itemRenderer = itemRenderer;
这里报错还是没有修改吗

另外

let url: string = FairyGUI.UIPackage.GetItemURL(pkgName, resName);
        console.log("---------->registerClass pkgName: "+pkgName + " resName: " + resName + " url: " + url );
        FairyGUI.UIObjectFactory.SetPackageItemExtension(url, $typeof(cls) );//这里注册自定类也注册不起呢
