Trouble using <f:ajax> on JSF 2.0
I posted a question here last week about using Ajax with J2EE and got and answer about the build in support of ajax with JSF 2.0开发者_JAVA技巧. Unfortunately I just cant seem to get any example of this to work!
I have tried out using different IDEs with different servers but I cant get this basic example to work.
A session scoped managed bean:
public class testBean
{
private String name;
public testBean() {}
public String getName(){
return name;
}
public void setName(String name){
this.name = name;
}
}
And the xhtml page:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core">
<head>
<title>Default title</title>
</head>
<body>
<h:form id="testForm">
<h:inputText id="test" value="#{testBean.name}" >
<f:ajax event="keyup" render="testForm:name" execute="testForm:test"/>
</h:inputText>
<h:outputText id="name" value="#{testBean.name}" />
</h:form>
</body>
</html>
From my knowledge the page should display the text that is written while it is being written right next to the inputText form, but that is not happening.
I hate making two topics about roughly the same thing but I really dont know whats wrong here, from what Ive read this code should work.
You have the wrong event specified in your f:ajax. Use keyup or keypress instead of click:
<h:inputText id="test" value="#{testBean.name}" >
<f:ajax event="keyup" render="name" execute="test"/>
</h:inputText>
the onclick / click event handler is only fired by a mouse click.
UPDATE:
Didn't notice it before:
I think you should use <h:head> instead of <head> to include all javascript resources for ajax correctly.
