Hi Guys,
I was tried to map the table without having an primary key, I got an error like"property is invalid in the mapping file. expected id property".
Then I tried with creating id property and i am not specified the column, even though I cannot proceed ... I caught up with an error " System.IndexOutOfRangeException: Index was outside the bounds of the array." and in the inner exception "Initialization of object failed : Could not compile the mapping document"

Is there any samples to create mapping without primarykey?

Thanks & Regards,
Nizam

No, because NHibernate depends on an identity property and a corresponding primary key.
