Hello.

I have the typical parent-child form for invoices (or orders) introducing=
=20
article lines with quantity, price and total amount. At the bottom of the=
=20
form a box should display the total amount of the invoice. This is=20
calculated using a trigger inside the postgresql database.=20

There is no refresh operation I can call from python, in the post-sync=20
event. I think that a requery operation won't do it, because it re-executes=
=20
the query for the main form, will reset the focus, eventually jump to=20
another record and do a lot of extra work that I don't need. I just want to=
=20
re-read the data for the current record of the main form. (excactly the=20
operation that is done after record insertion or update).

How could this be accomplished ?
