Render problem of jsf 2.0
I just want to rerender a tag(h:outputText) when I click one cell of a datatable using jsf 2.0, but my test showed me some error like that the tag id i set to be rerendered is not in the context of the cell tag.
my code is following:
index.xhtml
<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<h:head>
<title>Facelet Title</title>
<h:outputScript target="header" name="jquery.js" library="js"/>
<script type="text/javascript">
function showStatus(event) {
$("#status").text(event.status);
}
</script>
</h:head>
<h:body>
<h:form id="form1" prependId="false">
<h:dataTable id="table" value="#{TestBean.allUsers}" var="u">
<h:column>
<f:facet name="header">
<h:outputLabel value="Name"/>
</f:facet>
<h:outputLabel value="#{u.name}">
<f:ajax event="click" listener="#{TestBean.show(u)}" onevent="showStatus" render="out1"/>
</h:outputLabel>
</h:column>
</h:dataTable>
</h:form>
<h:outputText id="out1" value="#{TestBean.user.name}"/>
<div id="status"></div>
</h:body>
</html>
my test bean is:
TestBean.java
@ManagedBean(name="TestBean")
@RequestScoped
public class TestBean {
private User user;
private List<User> list;
/** Creates a new instance of TestBean */
public TestBean() {
}
public List<User> getAllUsers(){
list = new ArrayList<User>();
for (int i = 0; i < 10; i++) {
list.add(new User("Name"+(i+1),18+i,"DV"+(i+1)));
}
return list;
}
public void show(User user){
System.out.println("User nam is "+user.getName());
this.user = user;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
<f:ajax event="click" listener="#{TestBean.show(u)}" onevent="showStatus" render="out1"/>
The error appeared in this line.
if I change render value to "@all" it works, but I just want to render the only one tag, why must I set the render value "@all"?
Any suggestions?
Thanks in advance.
