And?

What's the problem with that???

A generator value is qualifying, not quantifying!

So you shouldn't care about gaps!

If you generate the pk-field in a trigger you've got a problem on your
client side that you can't continue working with this value (i.e. if you
want to add a master record and then immediately start inserting detail
records).

If you don't want to use the GeneratorLinks and need the value on the
client side you can use the BeforePost event of the query and assign a
value by calling the GEN_ID method from the IB_Query or IB_Connection.
