Update Results not Displayed in Oracle Text search with Transactional Index

Question

Hi,
I am working on a solution utilising Oracle Text to give me a probable list of matching records. The problem I have the table I am searching on is prepopulated with seed data and the application we are building is assigning a record and updating the details(columns) against it. This detail is what we are searching on using an Multi Column Datastore index which is refreshed every hr and also has the transactional parameter specified. Unfortunately the Transactional Index does not pick up the updated details, it only seems to work if I insert a new record (which will never happen). This to me sounds like a bug. Any assistance would be greatly appreciated.

Barbara,
I think you may have eluded to my problem. I haven't updated the "dummy" column
The table structure is as follows:
CREATE TABLE WAGN (
     WAGN               VARCHAR2(8) NOT NULL PRIMARY KEY,
     last_name          VARCHAR2(240),
     first_name          VARCHAR2(240),
     middle_name          VARCHAR2(240),
     date_of_birth     DATE,
     gender               VARCHAR2(1),
     status               VARCHAR2(1) NOT NULL,
     signature          RAW(64));
The preference creation is:
BEGIN
     ctx_ddl.create_preference('WAGN_NAME_SRCH', 'MULTI_COLUMN_DATASTORE');
     ctx_ddl.set_attribute('WAGN_NAME_SRCH', 'columns', 'last_name, first_name, middle_name, date_of_birth, gender');
END;     
The Index Creation statement is:
CREATE INDEX wagn_srch_idx1 ON WAGN(signature) --Dummy Column
INDEXTYPE IS ctxsys.CONTEXT
PARAMETERS ('DATASTORE WAGN_NAME_SRCH SYNC(EVERY "SYSDATE+60/24/60" PARALLEL 10) TRANSACTIONAL');
And a typical update statement is (contained with PL/SQL):
     UPDATE WAGN
          SET status = x_wagn_assigned_status,
               last_name = p_employee_details.last_name,
               first_name = p_employee_details.first_name,
               middle_name = p_employee_details.middle_name,
               date_of_birth = p_employee_details.date_of_birth,
               gender = p_employee_details.gender
          WHERE WAGN = l_wagn;
So my guess is that because the dummy column (signature) is not updated it is not being reflected in the transactional memory area.
