Hello, Again i see that the @PostConstruct is firing every time even though no binding attribute is used. See this code :-
<?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">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:c="http://java.sun.com/jsp/jstl/core">
<h:head>
<title>Facelet Title</title>
</h:head>
<h:body>
<h:form>
<c:forEach var="item" items="#{TestBean.listItems}">
<h:outputText value="#{item}"/>
</c:forEach>
<h:commandButton value="Click" actionListener="#{TestBean.actionListener}"/>
</h:form>
</h:body>
</html>
And this is the simplest possible bean in JSF :-
package managedBeans;
import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;
import javax.annotation.PostConstruct;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.ViewScoped;
@ManagedBean(name="TestBean")
@ViewScoped
public class TestBean implements Serializable {
private List<String> listItems;
public List<String> getListItems() {
return listItems;
}
public void setListItems(List<String> listItems) {
this.listItems = listItems;
}
public TestBean() {
}
@PostConstruct
public void init(){
System.out.println("Post Construct fired!");
listItems = new ArrayList<String>();
listItems.add("Mango");
listItems.add("Apple");
listItems.add("Banana");
}
public void actionListener(){
System.out.println("Action Listener fired!");
}
}
Do you see any behaviour that should cause postconstruct callback to fire each time? I think JSF 2.0 is highly unstable. If it has to fire PostConstruct each and every time what purpose does @ViewScoped serve. Why not to use @RequestScoped only? I thought i have made some mistake in my application. But when i created this simplest possible in JSF, i still get this error. Am i not understanding the scopes of JSF? or are they not testing it properly? Further, if you remove c:forEach and replace it with ui:repeat, then it works fine.
Waiting for replies to confirm whether it is bug or it is intentional to stop the programmers from using jstl?
