Sorry Fabio, I didn't have my code in front of me when I posted.
The version tag looks like this in my generated code (I am using an
FNH mapping) like this:
this.Version(x => x.Version).Column("Version").Generated.Always
().UnsavedValue("null");
This generates the following tag:
<version column="Version" generated="always" name="Version"
type="System.Byte[], mscorlib, Version=2.0.0.0, Culture=neutral,
PublicKeyToken=b77a5c561934e089" unsaved-value="null" />
But the problem still remains. Any thoughts?
