TAdvDBLookupComboBox

Good afternoon,

I've try to use the component in subject but it seems not working when the field specified in "Data Field property" is NULL.

The error occurs is: "OLE Error: generic error".

If I use a table with values populates all works fine.

You didn't manage NULL values?

thank you
L.

The problem is that for NULL there can't be a lookup relationship, so, I'm not sure how you'd expect the component to work for field values where there is no lookup relationship?
