主要是flex 在绑定里面加两个或者多个判断条件的情况。

比如visible="{ A && B}"表达这样一个意思时，出现标题的错误。 主要是xml无法解析 &&这样一个逻辑符号。所以要将他写出

visible="{(A)&&(B)}"这样就可以了。。

If you’ve ever written code in a binding tag and gotten aspecial character error try html-encoding the character like you’ddo if you were encoding regular text:

Error:

<mx :TextInput text= "{(_feed.url&&!_feed.isTemporary)?_feed.url:'Save Feed to generateURL'}" />

Works:

<mx :TextInput text= "{(_feed.url&amp;&amp; !_feed.isTemporary)?_feed.url:'SaveFeed to generate URL'}" />

It makes sense after the fact but before you actually do it, itjust looks odd to html-encode youractionscript.-翻译：运行的时候是能运行的通的，但是，在as代码里面，看上去有点怪怪的。。

大概的意思就是我上面的意思了。
