-------------------------------------
Environment: JBoss 4.0.5.GA, JBoss EJB3 RC9 Patch 1 on WIndows Vista Ent. Ed. MySQL without InnoDB (was: JBoss 4.0.5.GA, JBoss EJB3 RC9 Patch 1 on WIndows Vista Ent. Ed.)
> Cannot have several EAGER-fetches in one class
> ----------------------------------------------
>
> Key: EJBTHREE-935
> URL: http://jira.jboss.com/jira/browse/EJBTHREE-935
> Project: EJB 3.0
> Issue Type: Bug
> Environment: JBoss 4.0.5.GA, JBoss EJB3 RC9 Patch 1 on WIndows Vista Ent. Ed. MySQL without InnoDB
> Reporter: Oskar Carlstedt
>
> It is impossible to use FetchType.EAGER on more than one set in an Entity bean. Here is an example:
> public class SomeClass {
> @Id
> @GeneratedValue(strategy = GenerationType.IDENTITY)
> @Column(name = "id")
> private Integer id;
> ...
> @OneToOne(cascade = CascadeType.ALL, mappedBy = "theLink", fetch = FetchType.EAGER)
> private OneToOneTest oneToOneTest;
> @OneToMany(cascade = CascadeType.ALL, mappedBy = "theLink", fetch = FetchType.LAZY)
> private List<OneToManyTest1> oneToManyTest1 = new ArrayList<OneToManyTest1>();
> @OneToMany(cascade = CascadeType.ALL, mappedBy = "theLink", fetch = FetchType.EAGER)
> private List<OneToManyTest2> oneToManyTest2 = new ArrayList<OneToManyTest2>();
> @OneToMany(cascade = CascadeType.ALL, mappedBy = "theLink", fetch = FetchType.EAGER)
> private List<OneToManyTest3> oneToManyTest3 = new ArrayList<OneToManyTest3>();
> ...
> }
> Deploying this application will fail with the following message:
