Hello all,
I'm new to Nhibernate and new to this forum, so please, be generous.
The problem is that when I'm using the "optimistic-lock" attribute with <many-to-one> or <property> or <set> any other association or a property of a class, then I'm getting the "attribute not declared" (see below the details). I have found that a similar problem was asked for hibernate users
here. Is there a similar solution for Nhibernate users? In the provided mapping file the property that causes the exception is the <many-to-one> relationship, that has
Code:
optimistic-lock="false"
Thanks in advance.
