I'm not sure if there's enough information here to help you. There
seems to be a few problems with the design though.
You should make your enumeration with two fields, one Integer as the
primary key for the enumeration entity and another for your string
value VARCHAR(2) or whatever. Let EOF generate the primary keys (don't
make them class properties so they will not be used in your class
definition). You will be much better off letting EOF handle primary
and foreign keys. If you need a user presentable key then use a
separate field and put a unique index on it in the database.
If designed properly Direct to Java Client (D2JC) may give you exactly
what you want without having to change anything. I'd have to do some
testing to be sure of this.
Make sure you follow the rules defined in the D2JC book for enumeration
entities (i.e. make sure the relationships are set correctly etc.).
D2JC wants things configured a certain way and if you deviate too much
from what it expects your results will be less than desirable.
I'd be glad to help if you can provide a bit more information about
your basic design. How are your relationships configured? What is D2JC
giving you as a default widget? Is D2JC automatically setting your
entity as an enumeration or are you changing that manually with the
assistant? Any other information you can provide would be helpful.

Hi All,
I have a Direct to Java Client app that I am trying to configure a
field to
be a EOOneValueEnumerationController and it refuses to show any values
when
I click on the combo box. I have one entity listed in my enumeration
entities and it has a primary key that is a VARCHAR2. What is wrong?
Also,
how to I directly attach the values for the
EOOneValueEnumerationController
to a particular enumeration entity?
Thanks
Ed
