Does really nobody know something about my problem? Something like "this
is not possible at the moment" is also ok... :-)

Hi,
I have the following problem:
For simplicity, assume I want to store users in the database. Before
storing a user the first time in the database (using someNewUser.save),
I want to create a special unique number for this user (which we need in
our company) and store this number together with the new user. This
number is based on several values and some of them need to be read from
the database.
My first idea was to add something to beforeCreate in the meta object
but I'm not sure how to do the computation of the number together with
the save operation in one transaction (which is absolutely necessary)?
And are there better places to do this?
I read something about putting the whole request in one transaction but
this is not what I want. I'm currently only using the Mapper stuff
(because I want a pure scala ORM) and not the whole Lift framework.
Thanks in advance,
Julian
