Hi,


It seems that references between objects are broken in SVN head.

Simple code like:

public class AA {}
public class B { public virtual AA Ref { get; set; }}
...
AA aa = new AA ();
B b = new B ();
b.Ref = aa;

Save (aa);
Save (b);

fails with attached exception.

When some objects are present in database, query which returns object
which has reference on another object also fails with similar exception.

Could I rely on a "SVN head mostly works" and if something doesn't work,
report a bug, or should I always test against released versions?

Thanks,

Jan
