Could you check out the attached demo? It works for me with Laz trunk 
and fixes (both r57032) on Windows and Linux GTK2/QT (trunk tested 
only). The left grid shows the main dataset, the right grid is the 
lookup dataset. The lookup combo is at the bottom. Select an item from 
the combo and the CountryCode field should update accordingly. Also 
rotating the mouse wheel over the combobox works.
