Hello,

i am totally new to SEAM and JSF, so i hope you dont mind if this is a stupid question or posted to the wrong forum. I just couldnt find a example for this.

I have a Entity class called Contacts which looks like this

package gfm.entity;

import java.io.Serializable;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.Lob;
import javax.persistence.Temporal;
import javax.persistence.TemporalType;
import org.hibernate.annotations.CascadeType;
import org.jboss.seam.annotations.Name;
@Entity
@Name("contact")
public class Contact implements Serializable {
 private static final long serialVersionUID = 1L;

 @Id
 @org.hibernate.annotations.GenericGenerator(name="uuid_gen", strategy="uuid")
 @GeneratedValue(generator="uuid_gen")
 private String puid;

 private String title;
 private String firstName;
 private String middleName;
 private String lastName;

 private String company;
 private String department;

 @Temporal(TemporalType.DATE)
 private Date birthday;

 @Lob
 private String notes;

 @org.hibernate.annotations.CollectionOfElements
 @org.hibernate.annotations.IndexColumn(name="idx")
 @org.hibernate.annotations.Cascade(CascadeType.DELETE_ORPHAN)
 @JoinColumn(name="contact_puid")
 private List<StreetAddress> streetAddresses = new ArrayList<StreetAddress>();

 @org.hibernate.annotations.CollectionOfElements
 @org.hibernate.annotations.IndexColumn(name="idx")
 @org.hibernate.annotations.Cascade(CascadeType.DELETE_ORPHAN)
 @JoinColumn(name="contact_puid")
 private List<EmailAddress> emailAddresses = new ArrayList<EmailAddress>();

 @org.hibernate.annotations.CollectionOfElements
 @org.hibernate.annotations.IndexColumn(name="idx")
 @org.hibernate.annotations.Cascade(CascadeType.DELETE_ORPHAN)
 @JoinColumn(name="contact_puid")
 private List<CommNumber> commNumbers = new ArrayList<CommNumber>();

 // Getter and setter .....

}

Each contact could have an unlimited number of addresses, emailaddresses and phone and faxnumbers.

The question is, how do i reference a single streetaddress from within a JSF Page ? and how do i add new streetadresses to contact ? I hope i explained that right.

An example or code snippet would be great.

Thank you very much,

Stefan
