i set the attribute not-found='ignore' in a many-to-one element, but at runtime i'm getting an exception

"No row with the given identifier exists

Code between sessionFactory.openSession() and session.close():

IList<ReservationDetail> details = this.m_session.CreateCriteria(typeof(ReservationDetail)).Add(new EqExpression("Year", int.Parse(dgvPatients.SelectedRows[0].Cells[3].Value.ToString()))).Add(new EqExpression("Number", int.Parse(dgvPatients.SelectedRows[0].Cells[4].Value.ToString()))).List<ReservationDetail>();

Full stack trace of any exception that occurs:

in NHibernate.UnresolvableObjectException.ThrowIfNull(Object o, Object id, Type clazz) in C:\Documents and Settings\luke\Documenti\Riferimenti VS2005\NHibernate\NHibernate\UnresolvableObjectException.cs:riga 59

Name and version of the database you are using: Oracle 10g

Doesn't look exactly like full stack trace to me...

Ciao Luca...

Today a have no time to test the mapping.
Tomorrow i think i can make a test using "insert=false update=false" together with not-found="ignore".

Are you secure that the problem is in Availability property and not in ExamInfo ?

Can you make a separatelly test of your class ? (N.B. a UnitTest without grid view and so on)

Ops...
You are using comositeID..
Can you send the mapping of Availability too ?

Any way is better if you create a separate UnitTest.

hey guy this is visual studio debug output (see the attach!)



fabiomaulo, the exception say that CUP.Availability was not found, so i think the problem is there ;-)

this is Availability mapping file

Please create a JIRA attaching 2 simple class and it's mapping with composite ID.

Ciao Luca, domani dovrei avere tempo di guardarci.
Bye Luca, tomorrow may I have time to look inside.

Fabio.

P.S. a my friend would say: compositeId, session in front-end, dbGrid column to fetch objs... look like "spaghetti code" ;)

what does it means ?

compositeId : i'm using untouchable oracle schema, so i need to use those definitions;
session in front-end : i've only front-end, and i need a single session so...
dbGrid column to fetch objs : i'm not using dbgrid to fetch objects ??

and last but not least : i'm Italian and i love spaghetti with every sauces ;-)[/quote]

Luca.. i'm italian too.
create a JIRA and tomorrow i'm go to get a look.
