#24 OnCalcField does not seem to fire

[Anonymous]

I have a TIBQuery (4.52, D5). I am trying to use the
OnCalcField to fill in a, well, calculated field.

I used the field editor to make a TIntegerField of
type fkCalculated. The AutoCalcFields property of the
dataset is true, but the event never seems to
trigger. I just tried placing a ShowMessage in the
handler, to no avail.
