    <h1> JSF do not post a "execute doAction1"</h1> 
      <a4j:commandButton action="#{sample.showPanel}" value="Show Panel" 
       reRender="MyPanelShow"></a4j:commandButton> 

      <a4j:outputPanel id="MyPanelShow" > 


       <rich:panel rendered="#{sample.showPanel}" id="panel1"> 
        <h:inputText value="#{sample.name}" id="input1"></h:inputText> 
        <a4j:commandButton value="Ejecutar" action="#{sample.doAction1}" 
         reRender="MyPanelShow" id="action1"></a4j:commandButton>

Answer 1

, 내 행동은 ??? showPanel가 = true로 설정 showPanel 액션 doAction1을 실행할 수 없습니다 않습니다 내 JSF는 확인

rendered="#{sample.showPanel}" 

은 제출할 때 'true'로 평가됩니다.
