I have problems mapping a Collection of Strings and Enums in my entities. I have followed different advices, but nothing seem to work. I am using PlayFramework 2.0 and the provided Ebean as ORM. Here is an illustration class: package models; import java.util.*; import javax.persistence.*; import play.db.ebean.Model; @Entity @Table(name = "foo") public class Foo extends Model { private static final long serialVersionUID = 1L; private enum FooBar { FOO, BAR; } @Id public Long id; @ElementCollection @Enumerated(EnumType.STRING) @CollectionTable(name = "bar_foobar", joinColumns = @JoinColumn(name = "bar_id", referencedColumnName = "id")) @Column(name = "foobar") public List<FooBar> fooBars; @ElementCollection(targetClass = String.class) @CollectionTable(name = "bar_strings", joinColumns = @JoinColumn(name = "bar_id")) @Column(name = "string", nullable = false) public List<String> listOfStrings; @Basic public List<String> listOfStrings2; // Attempt to circumvent the issue, but this gives a strange error //public String[] arrayOfString; } The generated DDL when the application is started looks like this: create table foo ( id bigint not null, constraint pk_foo primary key (id)) ; I would expect to see both the tables bar_foobar and bar_strings being created, if the annotations were correct. If using the arrayOfString variable, I get a weired error-message upon application launch (which related to a random entity, not necessarily Foo.class PersistenceException: Error with [models.user.User] It has not been enhanced but it's superClass [class play.db.ebean.Model] is? (You are not allowed to mix enhancement in a single inheritance hierarchy) marker[play.db.ebean.Model] className
