jsf中有关<h:commandButton/>标签
我在Eclipse+myEclipse中自动生成标签

<h:commandButton actionlistener= "#{user.verify} "
action= "#{user.outcome} " rendered= "true " value= "实验 ">
</h:commandButton>
却出现如下错误：
……
Attribute actionlistener invalid for tag commandButton according to TLD
……
请问是怎么回事啊？
我改为
<h:commandButton value= "送出 "
actionListener= "#{user.verify} "
action= "#{user.outcome} "/>
就没关系！
谢谢各位！


[解决办法]
看看jsf in action
