Subject Re: Connect to Database calls Generator

I do use generatorlink property and there are no "false" generator
increase at start time in my app (ib 4.2ib, SQLmonitor run at start time).
I think that Helen did not suggest you to avoid generatorlink, but
avoid putting an empty dataset in edit state if not required.
It's good generate an ID before a new row is posted, but this I think
can be a problem in a master of a master-detail relationship, if you
"insert" the master, insert the detail and then post the detail (at
this poing has a null as master key).
I suggest you to try to isolate the origin of the "bad" generator
call, since it's not a good sign ;)
