Combobox with LOV showing ID but would like to display more meaningful text

Question

Hi, I'm experimenting with JDeveloper 11.2.
I have a base table/eo with an FK ID to another table/eo which is a lookup table.
On the base tables view I have created a combobox with LOV but it is showing the ID and I'd like it to show the name from the lookup table.
So rather than showing the ID 1 I'd like it to show James instead.
I can just about remember being able to do this in Oracle Designer.
I know this is something stupid but I've searched Google and not come up with anything.
CREATE TABLE ACCOUNTS
ACCOUNT_ID NUMBER NOT NULL,
ACCOUNT_LOGIN VARCHAR2(30 CHAR) NOT NULL,
FIRST_NAME VARCHAR2(50 CHAR) NOT NULL,
LAST_NAME VARCHAR2(50 CHAR) NOT NULL,
EMAIL VARCHAR2(150 CHAR),
CREATED_TIMESTAMP TIMESTAMP(6) WITH LOCAL TIME ZONE DEFAULT SYSTIMESTAMP NOT NULL
ALTER TABLE ACCOUNTS ADD (
CONSTRAINT ACCOUNTS_PK
PRIMARY KEY
(ACCOUNT_ID));
CREATE TABLE ACCOUNT_MODULE_ROLES
ACCOUNT_MODULE_ROLE_ID NUMBER NOT NULL,
ACCOUNT_ID NUMBER NOT NULL,
MODULE_ID NUMBER NOT NULL,
ACCOUNT_ROLE_ID NUMBER NOT NULL
ALTER TABLE ACCOUNT_MODULE_ROLES ADD (
CONSTRAINT ACCOUNT_ROLES_PK
PRIMARY KEY
(ACCOUNT_MODULE_ROLE_ID));
ALTER TABLE ACCOUNT_MODULE_ROLES ADD (
CONSTRAINT AMR_ACC_FK
FOREIGN KEY (ACCOUNT_ID)
REFERENCES ACCOUNTS (ACCOUNT_ID)
ON DELETE CASCADE
ENABLE VALIDATE);
I've created the LOV on AccountModuleRolesView.

Answer 1

1. Create a transient attribute AccountFirstName. - Created in AccountModuleRolesView1, attributes a transient string called AccountFirstName with an alias of VIEW_ATTR
2. Create a VA on accountId attribute. - VA? There is a tab called View Accessors and I have three, one for each of the FK's.
3. In attribute mapping ... Where abouts is that? After I've created the LOV?
map ... accountId to accountId I did this in the LOV, list return values, using the VA's I linked in.
and fristName to accountFirstName. Did this also in the same place.
4. In UI hints shuttle accountFirstName. The field doesn't show up in the list to shuffle, only the underlying eo attributes.
