做项目中出现的问题，不得不修改引擎底层。现把几点修改提出来，希望官方能在新版本中修改：
1、Templet中：getGrahicsDataWithCache方法希望做个容错。

/**
 * @private
 * 得到缓冲数据
 * @param  aniIndex   动画索引
 * @param  frameIndex 帧索引
 * @return
 */
public function getGrahicsDataWithCache(aniIndex:int, frameIndex:Number):Graphics {
   if(_graphicsCache[aniIndex] && _graphicsCache[aniIndex][frameIndex]){
              return _graphicsCache[aniIndex][frameIndex];
          }
   return null;
}

2、Text：语言包的使用形同虚设：

public function set text(value:String):void {
   if (this._text !== value) {
      var a:Array = (value + "").split("|");
      var p:Array;
      if(a.length > 1){
         p = a.slice(1);
                  lang(a[0],p);
      }else if(a.length == 1){
         lang(a[0]);
      }else {
         lang("");
      }

      isChanged = true;
      event(Event.CHANGE);
   }
}[/code][code]public function lang(text:String, args:Array = null):void {
   text = langPacks && langPacks[text] ? langPacks[text] : text;
   if (!args || args.length <= 0) {
      this._text = text;
   } else {
      for (var i:int = 0, n:int = args.length; i < n; i++) {
         text = text.replace("{" + i + "}", args[i]);
      }
      this._text = text;
   }
}

3、HTTPRequest中错误输出：前面的status和statusText都是空的根本打印不出任何东西。

/**
 * @private
 * 请求出错侦的听处理函数。
 * @param  e 事件对象。
 */
protected function _onError(e:*):void {
   error("Request failed Status:" + this._http.status + " text:" + this._http.statusText + e.toString());
}

4、URL中formatURL方法中使用customFormat传入参数有问题, 多了个base

public static function formatURL(url:String, base:String = null):String {
   if (!url) return "null path";
   //如果是全路径，直接返回，提高性能
   if (url.indexOf(":") > 0) return url;
   //自定义路径格式化
   if (customFormat != null) url = customFormat(url);
   
   var char1:String = url.charAt(0);
   if (char1 === ".") {
      return formatRelativePath((base || basePath) + url);
   } else if (char1 === '~') {
      return rootPath + url.substring(1);
   } else if (char1 === "d") {
      if (url.indexOf("data:image") === 0) return url;
   } else if (char1 === "/") {
      return url;
   }
   return (base || basePath) + url;
}

5、MiniFileMgr中downFile只对200返回码做处理，实际会出现304 500 或者其他的错误码，并不会进入fail流程

public static function downOtherFiles(fileUrl:String, callBack:Handler = null, readyUrl:String = "", isSaveFile:Boolean = false, isAutoClear:Boolean = true):void {
    wxdown({
        url: fileUrl, success: function (data:Object):void {
            if (data.statusCode === 200) {
                if ((MiniAdpter.autoCacheFile || isSaveFile) && readyUrl.indexOf("wx.qlogo.cn") == -1 && readyUrl.indexOf(".php") == -1)
                    copyFile(data.tempFilePath, readyUrl, callBack, "", isAutoClear);
                else
                    callBack != null && callBack.runWith([0, data.tempFilePath]);
            }else {
                callBack != null && callBack.runWith([1, data]);
            }
        }, fail: function (data:Object):void {
            callBack != null && callBack.runWith([1, data]);
        }
    });
}

public static function downFiles(fileUrl:String, encoding:String = "ascii", callBack:Handler = null, readyUrl:String = "", isSaveFile:Boolean = false, fileType:String = "", isAutoClear:Boolean = true):void {
    var downloadTask:* = wxdown({
        url: fileUrl, success: function (data:Object):void {
            if (data.statusCode === 200) {
                readFile(data.tempFilePath, encoding, callBack, readyUrl, isSaveFile, fileType, isAutoClear);
            } else {
                callBack != null && callBack.runWith([1, data]);
            }
        }, fail: function (data:Object):void {
            callBack != null && callBack.runWith([1, data]);
        }
    });
    //获取加载进度
    downloadTask.onProgressUpdate(function (data:Object):void {
        callBack != null && callBack.runWith([2, data.progress]);
    });
}
