Steps to Reproduce:

I have converted a working application develop with Delphi 6 to Delphi 7.
This application use BDE/ODBC connection to work with an MSAccess database.
I use lot of TQuery with DataSource assigned (to get Master/Detail
relationship by same-name parameters completition) and I use these dataset
by TDBLookupComboBox.
I click the TDBLookupComboBox"Master", then I click the
TDBLookupComboBox"Detail" and I get an exception "Field '' not found".
I found UpdateListFields method is missed on TDBLookupComboBox.DropDown.
I think it is a Delphi 7 bug but I would like to know more becouse I cannot
deploy this application.
thank you

The text in the Steps should be put into the Description instead. Please fix.

I posted a simular report as 5384. It has a new DBCtrls.pas file attached that seems to solve this problem.
