a4j:ajax Will get/set bean, but will not rerender on page.

slammajamma Jun 11, 2013 3:07 AM

Hello all,

I have been tring to replicate the fucntionaly shown on richfaces showcases.http://showcase.richfaces.org/richfaces/component-sample.jsf?demo=ajax&sample=ajax&skin=blueSky

I have used the code given on the site, only changing the name of the bean:

<h:form>

<h:inputText value="#{customer.extCustomerId}">

<a4j:ajax event="keyup" render="out" />

</h:inputText>

<h:outputText value="#{customer.extCustomerId}" id="out" />

</h:form>

I have ensured that there are no client or server side errors and that the page this will be displayed on contains the header tag.

I have placed System.out messages in the getter and setter methods customer.extCustomerID.

When the inputText field is used, it should populate right next to the box as in the example. It does not.

If I preform a manual refresh, the text will appear from the previous update. Also, when ever I enter information into the inputText feild, I can see the System.out messages in the server log. The system is getting and setting.

I am very confused... the code is talking wiht my database, but it is not rerendering so that the text appears.

I am using richfaces 4.3.2.Final in netbeans.

Any idea on how to get the text to rerender?

Thanks

Hello Mitchel,

the problem will be somewhere else than in this snippet. Could you please post (or attach) complete facelet and bean code ?

I have re-constructed this issue on a test project to make illistration easier.

Here is the bean:

package test;

import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;

/**
*
* @author michael
*/
@ManagedBean(name="test")
@SessionScoped
public class test{

    private String i = "";

    /**
     * Creates a new instance of test
     */
    public test() {
    }

    /**
     * @return the i
     */
    public String getI() {
        System.out.println("Getting");
        return i;
    }

    /**
     * @param i the i to set
     */
    public void setI(String i) {
        System.out.println("Setting");
        this.i = i;
    }
}

Hmmm... that is strange...

I am running windows 7, tomcat 7, chrome/mozilla

You have me on the implementation... I am using what ever is bundled wiht netbeans 7.3. How can I make the distinction?

The lib is named JSF 2.1 - javax.faces.jar. It breaks down like... com.sun.faces.*

I had to rip netbeans apart.... but I got this working. It had something to do wiht the way the library was built.

Thank you for your help... Knowing that the code was the first step in the right direction!
