I am relatively new to IBO and still learning the ins and outs of it.
I have practically memorized the article "Configuring
TIB_LookupCombo" and still cannot resolve the following problem. If
anyone can tell me what I am missing, I would be very grateful - not
to mention able to move forward again with my project!

Situation: I using TIB_Grid in read-only mode to display selected
rows from a TIB_Query component and have other components to edit the
fields. I am using TIB_LookupCombo components as well as some other
controls.

Problem: I am unable to change the ProgramDescription data in the
field referenced by the LookupCombo box. The data displays correctly
in the lookupcombo and all the values are shown correctly in the
dropdown when selected. Yet, I am unable to change the value of the
field.

Details: (hopefully I am providing all relevant information)

Using Delphi 6 with IBO v4 something (forget exactly).

Primary Table (IB_Query component)
"quProgram" with "dsProgram" as datasource

Select

person.firstname,
person.middlename,
person.lastname, 'LNF'))
from CASEMANAGER join Person P on CaseManager.PersonID =
P.PersonID

CounselorName
, CP.IsPrimary
, CP.DATESTARTED
. . . (many other fields ommitted)
