   @aharui 
   **I have replaced** 
   **<mx:LinkButton styleName="htmlLink"  label="{data.at_Name}" toolTip="Save File"												   
     click="btnDownload_clickHandler(data.at_Name,data.at_Bytes,data.at_Status)"/>**
   
   ```
   private function btnDownload_clickHandler(name:String,file:mx.utils.ByteArray,status:String):void {
           if(status!= "0") {
               frd = new mx.net.FileReference();										
               frd.addEventListener(org.apache.royale.events.Event.OPEN, openHandler);	
               frd.save(file,name);
               }
              else
   	       Alert.show("File has been Removed.");
   	    }
   ```
   
   
   **With**
   ```
   <mx:DownloadButton styleName="htmlLink" id="downloadButton"  label="{data.at_Name}"
    toolTip="Save File"											   
    click="btnDownload_clickHandler(data.at_Name,data.at_Bytes,data.at_Status)"/>
   ```
   
   ```
   private function btnDownload_clickHandler(name:String,file:mx.utils.ByteArray,status:String):void {						
   	if(status!= "0") {
              downloadButton.defaultFileName = name;	
              downloadButton.data = menuDataXMLList.toString()										 
           }
          else
   	   Alert.show("File has been Removed.");
   	}
   
   <fx:Declarations>
   	  <fx:XMLList id="menuDataXMLList">
   		<menuitem label="label-1">			
   			<menuitem label="label-1-1"/>			
   			<menuitem label="label-1-2"/>			
   		</menuitem>
   		<menuitem label="Switch Locale" id="admin" >			
   			  <menuitem label="label-2-1"/>			
   			  <menuitem label="label-2-2"/>			
   			  <menuitem label="label-2-3" id="admin" />
   		</menuitem>
   	      </fx:XMLList>
   	    </fx:Declarations>
   ```
   
   
   if i remove   **downloadButton.data = menuDataXMLList.toString()** then file Name is shown
   if i added  **downloadButton.data = menuDataXMLList.toString()** file Name doesn't visible,in both situation file download doesn't work.
   
   As discussed in (https://github.com/apache/royale-asjs/issues/838) I have added
   ```
   COMPILE::JS {
     var saveData = (function () {
   	var a = document.createElement("a");
   	document.body.appendChild(a);
   	a.style = "display: none";
   	return function (data, fileName) {
   	var json = JSON.stringify(data),
   	blob = new Blob([json], {type: "octet/stream"}),
   	url = window.URL.createObjectURL(blob);
   	a.href = url;
          a.download = fileName;
          a.click();
          window.URL.revokeObjectURL(url);
         };
   }());
   var data = { x: 42, s: "hello, world", d: new Date() },
   fileName = name;
   saveData(data, fileName);
   } 
   ```
   
   But after this there's a compilation Error 
   Implicit type coercion of blob from Object to etc
   Access of possibly undefined URL with reference window
   So i commented this part.
   
   I am trying to fix this issue from last 2 to 3 days with multiple changes,nothing works for me,
   I you have time then please write a correct code for me,or instruct me to write code
