I am just getting started with SEAM. I tried the first few examples, and got
them working, so in my exuberence I decided to try out the EntityHome example
in chapert 14 of the onling doc. Whenever I try to persist the Person, it fails
with validation errors. What is interesting is that the validation errors cause
the page to fail instead of displaying the errors in the browser like the
previous examples do. The root of the problem is:
Caused by: org.hibernate.validator.InvalidStateException: validation failed
for: org.jboss.seam.example.registration.Person
I cannot for the life of me figure out why validation is failing. My entity
bean, entityhome, and jspx page is displayed below. Any hints on what the
problem is would be appreciated. I have not idea how to troubleshoot this
problem, so any help at all would be appreciated.
Entity Bean :
| @Entity
| @Table(name="persontable")
| public class Person {
| private Long id;
| private String firstName;
| private String lastName;
| //private Country nationality;
| @Id @NotNull @GeneratedValue
| public Long getId() {
| return id;
| }
| @Column(name="firstname",length = 45)
| @Length(max = 45)
| public String getFirstName() {
| return firstName;
| }
|
| @Column(name="lastname", length = 45)
| @Length(max = 45)
| public String getLastName() {
| return lastName;
| }
|
| public void setFirstName(String firstName) {
| this.firstName = firstName;
| }
|
| public void setId(Long id) {
| this.id = id;
| }
|
| public void setLastName(String lastName) {
| this.lastName = lastName;
| }
|
| }
|
EntityHome:
| @Name("personHome")
| public class PersonHome extends EntityHome<Person> {
| /**
| *
| */
| private static final long serialVersionUID = 219059304048820709L;
| @RequestParameter Long personId;
| @In EntityManager entityManager;
|
| public Object getId() { return personId; }
| public EntityManager getEntityManager() { return entityManager; }
|
| }
|
