I made a simple and clean example which manifests my problem. Let's say we
have two domain classes: Movie and Actor. We have collection (List) of
movies, and every movie has a collection (List) of actors.
Actor.java:
-----------------------
public class Actor {
private String name;
public Actor() { }
public Actor(String name) { this.name = name; }
public String getName() { return name; }
public void setName(String name) { this.name = name; }
}
-----------------------
Movie.java:
-----------------------
import java.util.ArrayList;
import java.util.List;
public class Movie {
private String title;
private List actors = new ArrayList();
public Movie(String title, List actors) {
this.title = title;
this.actors = actors;
}
public String getTitle() { return title; }
public void setTitle(String title) { this.title = title; }
public List getActors() { return actors; }
public void setActors(List actors) { this.actors = actors; }
}
-----------------------
This is MovieManager class, which is JSF managed bean with request scope. It
has a method getMovies which is used to populate outer h:dataTable element.
MovieManager.java:
-----------------------
import java.util.ArrayList;
import java.util.List;
public class MovieManager {
public MovieManager() { }
public List getMovies() {
List movieList = new ArrayList();
List actorList = new ArrayList();
actorList.add(new Actor("Joe I Smith"));
actorList.add(new Actor("Joe II Smith"));
actorList.add(new Actor("Joe III Smith"));
Movie movie = new Movie("Movie1", actorList);
movieList.add(movie);
return movieList;
}
}
-----------------------
Finally, next goes jsp page with two h:dataTable elements:
-----------------------
<%...@page contentType="text/html" pageEncoding="UTF-8"%>
<%...@taglib prefix="h" uri="http://java.sun.com/jsf/html"; %>
<%...@taglib prefix="f" uri="http://java.sun.com/jsf/core"; %>
<f:view>
<h:dataTable value="#{movieManager.movies}" var="movie" >
<h:column>
<h:outputText value="#{movie.title}" />
</h:column>
<h:column>
<h:dataTable value="#{movie.actors}" value="actor" >
<h:column>
<h:outputText value="#{actor.name}" />
</h:column>
</h:dataTable>
</h:column>
</h:dataTable>
</f:view>
-----------------------
What I'm trying to do here is make a table which lists movies, and which
lists all actors for current movie. But, result is showing only movies,
without actors, and without any exception. How to?
