cool, but both solutions look difficult to implement with IBO, that I am
using.

The problem with these controls is that you lose the atomic nature of the
master-detail record: the header and every single row start lives of their
own <g>

there is already a foreign key in the detail table that prevents the master
to be deleted first.

If I apply the control you suggest, it seems that nobody will be able to
delete a whole (master-detail) record any more...

spero di consegnare gran parte della nuova versione gia' lunedi'.
