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!
