As far as i understood all this, i have to use native, if i want to provide
my own ID generation. And i need this because the DB uses a TBL_IDEN for
ID's.
And in case of the PInfo Class there is no TBL_IDEN entry because the ID
results from the StrIdent. So, since all the NH ID generators will not work,
i have to use my own.
Am schrieb John Davidson <[email protected]>:
Why do you need that override if you want to use native. If you are using
native, then there should be no override that sets the id value anywhere
in your code.

I don't really want to manage the ID value in code. That's why i use the
IdentifierGenerator with the
overridden Generate method. So the ID is assigned from NH. I never touch
the ID in my code.
