Hi Marco

Today I got the same problem in Delphi and I guess I found the reason
for it, which is VCL related:

the ComboBox is setting the value in a way
Field.Value = NewValue
setting it as a variant.

In unit DB in TLargeIntField.SetAsLargeInt the code is
AccessError('Variant')
instead of
SetAsLargeInt(Value)

I guess it's a left over in the VCL from the time when Variant where
not able to deal with Int64!

I guess that C++ Builder has similar problem.

Cheers
Daniel
