[jboss-user] [EJB 3.0] - How to map an array or a list of enums?

Hi folks,

In EJB 3.0 via Seam 1.2.1.GA we want to persist an entity with an array of enums.

In the entity

| public UnderwritingConcernEnum[] getConcerns() {
|      return concerns;
|   }
|
|   public void setConcerns(UnderwritingConcernEnum[] concerns) {
|      this.concerns = concerns;
|   }
|


| public enum UnderwritingConcernEnum {
|
|   REINSURANCE("Reinsurance", "", "Re"),
|   INSUREDS_REQUEST("Insured's Request", "", "IRt"),
|   OLDER_ORNATE_STRUCTURE("Older Ornate Structure", "", "OOSe"),
|   VALUATION("Valuation", "", "Vn"),
|   LIABILTY_ACTIVITIES("Liability Exposures/Activities", "", "LAs"),
|   OTHER("Other (Be Specific)", "", "Or");
|
|   private final String label;
|   private final String description;
|   private final String value;
|
|   UnderwritingConcernEnum(String label, String description, String value) {
|      this.label = label;
|      this.description = description;
|      this.value = value;
|   }
|
|   public String getLabel() {
|      return label;
|   }
|
|   public String getDescription() {
|      return description;
|   }
|
|   public String getValue() {
|      return value;
|   }
| }
|

We have tried using the ordinal enumeration attribute, and also removing it. Either way, this entity will no be persisted failing with the error.

There is seemingly no documentation on how to do this. Please talk me off of the ledge on this one.
