在Flex中使用Flexpaper

Question

  以前在Jsp中使用Flexpaper觉得很不错，使用的时候没有什么过多的问题。现在做了一个Flex的开发，里面要嵌入文档，本以为Flexpaper在Flex中会更好用，但是里面的全屏却不能用。原来只用的官方文档中的一段代码嵌入，发现点击全屏的时候整个页面都花了。<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" width="100%" height="100%" xmlns:fp="com.devaldi.controls.flexpaper.*"> 
<fp:FlexPaperViewer width="520" height="450" Scale="0.6" SwfFile="{escape('Paper.swf')}" /> 
</mx:Application>  后来用了下面这种方法。有一个全屏是可以了，不过不是当前窗口的变化，而是父窗口，那也flex也页面全屏了。<?xml version="1.0" encoding="utf-8"?>
