Hank,

Changing grid_toolbar to a regular grid_ solved the problem.

Now, do you know what determines slcFKExpression and is there a way to specify it correctly in design time?

I changed a structure in one of my tables - added MakeID PK field. This table is used as a picklist for another table, but the relation is based on the name field (no sure which genius designed that application before it was handled to us). So, now VPME determines (incorrectly) the wrong FK Expression.

Thanks a lot in advance.
