用Flex4开发的上传文件模块在火狐下遇到点问题，请赐教
我把网页和SWF文件放在同一目录下，在IE和火狐下都能正常上传文件，网页代码如下：
- HTML code
<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="400" height="24" id="Object1"> <param name="movie" value="Upload.swf" /> <param name="quality" value="high" /> <param name="bgcolor" value="#ffffff" /> <param name="allowScriptAccess" value="sameDomain" /> <param name="allowFullScreen" value="true" /> <!--[if !IE]>--> <object type="application/x-shockwave-flash" data="Upload.swf" width="400" height="24"> <param name="quality" value="high" /> <param name="bgcolor" value="#ffffff" /> <param name="allowScriptAccess" value="sameDomain" /> <param name="allowFullScreen" value="true" /> <!--<![endif]--> <!--[if gte IE 6]>--> <p> Either scripts and active content are not permitted to run or Adobe Flash Player version 10.0.0 or greater is not installed. </p> <!--<![endif]--> <a href="http://www.adobe.com/go/getflashplayer"> <img src="http://www.adobe.com/images/shared/download_buttons/get_flash_player.gif" alt="Get Adobe Flash Player" /> </a> <!--[if !IE]>--> </object> <!--<![endif]--></object>
------------------------以下是问题产生代码----------------------
但我把swf文件放在与网页同级的一个目录Common中后，在IE下能正常上传文件，但在火狐中不能上传文件，网页代码如下：
- HTML code
<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="400" height="24" id="Object1"> <param name="movie" value="Common/Upload.swf" /> <param name="quality" value="high" /> <param name="bgcolor" value="#ffffff" /> <param name="allowScriptAccess" value="sameDomain" /> <param name="allowFullScreen" value="true" /> <!--[if !IE]>--> <object type="application/x-shockwave-flash" data="Common/Upload.swf" width="400" height="24"> <param name="quality" value="high" /> <param name="bgcolor" value="#ffffff" /> <param name="allowScriptAccess" value="sameDomain" /> <param name="allowFullScreen" value="true" /> <!--<![endif]--> <!--[if gte IE 6]>--> <p> Either scripts and active content are not permitted to run or Adobe Flash Player version 10.0.0 or greater is not installed. </p> <!--<![endif]--> <a href="http://www.adobe.com/go/getflashplayer"> <img src="http://www.adobe.com/images/shared/download_buttons/get_flash_player.gif" alt="Get Adobe Flash Player" /> </a> <!--[if !IE]>--> </object> <!--<![endif]--></object>
不知为何故。先谢谢了
[解决办法]
object互相嵌套有问题吧，应该是embed标签嵌套在object里面比较多
