Problem mapping collection of enums

Question

we get the following error:
org.apache.openjpa.util.MetaDataException: Type "class com.project.model.util.enumeration.HaeftelseSaerligeLaanevilkaar" is an enumeration and therefore cannot be made persistent.
we are using the following annotation:
@javax.persistence.Enumerated(javax.persistence.EnumType.STRING)
@org.apache.openjpa.persistence.PersistentCollection(elementEmbedded = true)
private java.util.Collection<com.project.model.util.enumeration.NoteringsType> noteringerCollection = new java.util.HashSet<com.project.model.util.enumeration.NoteringsType>();
noteringsType is a standard java 1.5 enum
Are we doing something wrong?

Hey jsutherl,
Thx for your help.
I decided to give EclipseLink a shot. After adding @BasicCollection, @CollectionTable, and @Converter, i was hoping to see a special collection table generated in the database for my Permission Enum. But instead nothing more than a Blob column was created. Did I do something wrong?
@Entity
@TypeConverter(
     name="StringToPermission",
     dataType=String.class,
     objectType=Permission.class
public class AccessLevel extends PersistentDomainObject implements Comparable<AccessLevel> {
     @Column(nullable=false, unique=true)
     private String name;
     private String description;
     @Column(nullable=false)
     private int rank;
     @Column(nullable=false)
     private boolean admin;
     private ArrayList<Permission> permissions = new ArrayList<Permission>();
     * @return the permissions
     @BasicCollection(
     fetch=FetchType.EAGER
     @CollectionTable
@Convert("StringToPermission")
     public List<Permission> getPermissions() {
          return permissions;
     * @param permissions the permissions to set
     public void setPermissions(ArrayList<Permission> permissions) {
          this.permissions = permissions;
I also tried the above without the converter, on the field instead of the method, etc. In every single instance no special collection table was generated.
Thx!
