RichFaces를 배우고 있습니다. .xhtml에 a4j : commandButton을 추가했습니다. 다음은 내 .xhtml 코드, 나는 그래서 내가 어떤 A4J 필터a4j : commandButton이 작동하지 않습니다. 클릭시 아무런 작업이 수행되지 않습니다.
그러나 A4J 부여하지 않은 richfaces 4를 사용하고

<h:panelGrid column="2">
<h:inputText value="#{echoBean.name}"/>

<h:outputText value="Count" />
<h:outputText id="countTxt" value="#{echoBean.count}" />
</h:panelGrid>
<a4j:commandButton value="Send" actionListener="#{echoBean.incrementCount}" reRender="echoTxt, countTxt"/>
</rich:panel>
</h:form>
</h:body>
</html>
입니다있는 명령이 작동하지 않습니다. 클릭시 아무런 조치도 취하지 않습니다. 그리고 스택 추적에 오류가 없습니다.
내가 누락 된 항목이 있습니까?
감사
업데이트 : 조치하여 ActionListener를 교체 한

서버 로그/firebug에 오류가 있습니까? – Daniel
@Daniel - 서버 로그에 오류가 없습니다. 실제로 텍스트 필드의 지정된 문자열의 길이가 OutputText에 표시 될 것으로 예상됩니다. 그것은 정상 commandButton과 함께 일어나고 있습니다. 하지만 a4j : commandButton을 사용하면 전혀 작동하지 않습니다. – droidsites
