Ah ok, that sounds good. But the user can not change the StrIdent. It is
generated by an other application and is unique.
But why says the exception "ID was altered from 1234 to 1234"? 1234 equals
1234 so where is the modification?
Anyway, i changed it to assigned now.

If an user can change the StrIdent property of an already persisted
object, you will get the exception you shown on the first mail.If that
your case, you need to map the POID as assigned. And you can write your
property as follows:
public string StrIdent {get; set;}
public int Id {
get { return int.Parse(StrIdent); }
set { StrIdent = value.ToString(); }
}
Then in your mappings:
name="Id">
class="assigned" />

for 2)
that's what i'm doing. I did override the NativeIdentifierGeneratorClass
Property and return
there my Id generator. Therefore every id mapping is marked as "native".
for 3)
I do this now. But i really don't understand why the exception occurs
when using the
id generator. I wanted to avoid the assigned id because of the need to
use save/update
and i don't want this "logic" to assign the ID in the code of my entity
class.
