[jboss-user] [JBoss Seam] - @In EntityManager is null when create an object from named b

[cftdanny]

If there is a bean named database, which @In entity manager:

@Name("database")
  | @AutoCreate
  | public class Database {
  | 
  | 	@In
  | 	private EntityManager entityManager;
  | 	
  | 	public Table createTable() {
  | 		return new Table(this);
  | 	}
  | 	
  | 	public User getUser(Long id) {
  | 		return this.entityManager.find(User.class, id);
  | 	}
  | }

And a table (like DAO, just work with User table):
public class Table {
  | 
  | 	private Database database;
  | 	
  | 	public Table(Database database) {
  | 		this.database = database;
  | 	}
  | 	
  | 	public User getUser() {
  | 		return this.database.getUser(0L);
  | 	}
  | }

If create table directly in bean, it will be ok, but if create table from Database, the entityManager in Database will be null. The following is test code:

public class Test() {
  | 
  | 	@In
  | 	private Database database;
  | 
  | 	public void execute() {
  | 		// The following code execute successfully
  | 		Table t1 = new Table(this.database);
  | 		User user1 = t1.getUser();
  | 		System.out.println(user1.toString());
  | 		
  | 		// The following code will cause error
  | 		// The entitymanager of database is null
  | 		Table t2 = this.database.createTable();
  | 		User user2 = t2.getUser();
  | 	}
  | }

Is there limited that we can not create a child bean from parent bean if child bean reference to parent bean?
