Oracle ADF h：commandButton f：ajax无法正常工作

Question

Trying to update a page through Ajax. 尝试通过Ajax更新页面。 Click a button and print out a counter on the page. 单击一个按钮，然后在页面上打印一个计数器。

The following code works when deployed with JSF 2.0 mojarra on a Tomcat 7. It does not work when deployed from JDeveloper 11g to the built in Weblogic server. 以下代码在Tomcat 7上与JSF 2.0 mojarra一起部署时有效，而从JDeveloper 11g部署到内置Weblogic服务器时则无效。 The count variable does get incremented, but the page is reloaded each time when using ADF. count变量确实会增加，但是每次使用ADF时都会重新加载页面。

Backing Bean: 后备豆：

import javax.faces.bean.*;
import javax.faces.event.ActionEvent;

@ManagedBean(name="countBean")   
@SessionScoped
public class CountBean {
    Integer count=1;
    public void incrementCount(ActionEvent event) {
        ++count;
    }
    public Integer getCount() { return count;}
    public void setCount(Integer count) {   this.count = count; }           
}

JSF-page: JSF页面：

<h:body>
<h3>Ajax count</h3>
<h:form>
<h:commandButton id="cb" value="Increment count" 
   actionListener="#{countBean.incrementCount}">
    <f:ajax event="click" execute="cb" render="ot" />
</h:commandButton>
<br/><br/>
Counter = <h:outputText id="ot" value="#{countBean.count}"/>
</h:form>
</h:body>
</html>

Answer 1

I found the answer myself: 我自己找到了答案：

<af:commandButton text="increment count" id="cb1" actionListener="#{countBean.incrementCount}" partialSubmit="true"/>

Counter = <af:outputText id="ot" value="#{countBean.count}" partialTriggers="cb1"/>
