Virtual Table: incomplete lookup field information ERROR

Post by kurdadze » Sun 25 Sep 2005 08:53

Does anybody knows what do i have to fill except these fields:

LookupResultFields;
LookupKeyFields;
LookupDataSet;
KeyFields;
FieldKind=fkLookup

to make a new "lookup field" in VirtualTable? Even though all(!) fields excep necessary are filled, it gives me an error: The information is incomplete?

Does anybody knows the technology of making such lookup fields and can provide steb-by-step instructions?

We cannot reproduce your problem.
Yes, that is enough. Please take a look at TField.ValidateLookupInfo function in debug mode.
