New User Lazy Load Question
Hello.
I'm just getting my start in the seam framework. I've used the seam-gen to setup the base of my project.
I have a basic site up where new users and register and login. What I'm trying to add now is the ability for users to add phone numbers to their account. I want to have the ability to have multiple phone number records per user (mobile, office, home, etc) thus it's set as a OneToMany
@Entity
@Name("user")
@Scope(SESSION)
public class User implements Serializable
{
private static final long serialVersionUID = -5311104884213351414L;
private long id;
private String username;
private String password;
private String firstname;
private String lastname;
private List <Phone> phones;
public User() {}
@Id @GeneratedValue
public long getId()
{
return id;
}
public void setId(long id)
{
this.id = id;
}
@Length(min=5, max=50)
public String getUsername()
{
return username;
}
public void setUsername(String username)
{
this.username = username;
}
public String toString()
{
return "User(" + username + ")";
}
@NotNull
@Length(min=5, max=15)
public String getPassword()
{
return password;
}
public void setPassword(String password)
{
this.password = password;
}
@NotNull
@Length(max=100)
public String getFirstname()
{
return firstname;
}
public void setFirstname(String firstname)
{
this.firstname = firstname;
}
@NotNull
@Length(max=100)
public String getLastname()
{
return lastname;
}
public void setLastname(String lastname)
{
this.lastname = lastname;
}
@OneToMany(mappedBy="user")
public List <Phone> getPhones() {
return phones;
}
public void setPhones(List <Phone> phones) {
this.phones = phones;
}
}
@Entity
@Name("phone")
@Scope(SESSION)
public class Phone implements Serializable
{
private static final long serialVersionUID = -8926240091475742891L;
private long id;
private String name;
private String number;
private User user;
public Phone () {}
@Id @GeneratedValue
public long getId()
{
return id;
}
public void setId(long id)
{
this.id = id;
}
@NotNull
@Length(min=2, max=15)
public String getName()
{
return name;
}
public void setName(String name)
{
this.name = name;
}
@NotNull
@Length(min=10, max=50)
public String getNumber()
{
return number;
}
public void setNumber(String number)
{
this.number = number;
}
@ManyToOne
public User getUser()
{
return user;
}
public void setUser(User user)
{
this.user = user;
}
}
What I'm trying to get working is just a list of the current logged in users phone records.
<f:subview id="phones"
rendered="#{!empty(phones)}">
<p>You have the following Phone Numbers Stored:</p>
<h:dataTable value="#{user.phones}" var="id">
<h:column>
<h:outputText value="#{phones.number}"/>
</h:column>
</h:dataTable>
</f:subview>I'm guessing it's something thats wrong in my ui code, but I don't see any examples that have simple mapped tables. Can someone point me in the right direction? How would I call and present the List of phones from my page?
