[leoloko]

Hi,

I have two Entitys basics.

@Entity
public class Category {
    @Id
    @GeneratedValue
    private Long id;
    private String name;
    @OneToMany(mappedBy="category")
    private List<Product> products;

    setters and getters

}

@Entity
public class Product {
    @Id
    @GeneratedValue
    private Long id;
    private String name;
    @ManyToOne
    private Category category;

    setters and getters

}

Im go to seam console and type seam generate-ui and build de beans and views .xhtml

im open browser and click in create category but the exception is launched:

Exception during request processing:
Caused by javax.faces.FacesException with message: "Problem in renderResponse: javax.el.ELException: /CategoryEdit.xhtml @88,68 rendered="#{empty categoryHome.products}": Error reading 'products' on type com.mydomain.test.CategoryHome_$$_javassist_4"

Somebody help-me?

from my experience, collection entities only work if you're using Set's, not lists.

Hi John,

im using in Set's or Get's ?

@Entity
public class Category {
    @Id
    @GeneratedValue
    private Long id;
    private String name;
    @OneToMany(mappedBy="category")
    private _Collection_<Product> products;

    setters and getters

}

Try this...John has right. I always use Collection, not List.
