TVirtualTable calculated problem

I have defined a Field as "calculated" and put the calculation in the "onGetText" event for the Field. Works fine when the field is displayed in the DBGrid, but when i try to retrieve the value with the FieldByName method, the result is empty.

TVirtualTable does not create internal buffer for saving values of calculated and lookup fields, therefore to get the value of this field you should use the TField.Text property.
