Hi Richard,
Now I think I found the problem. I have a function IncrementAmount
(decimal value). This function was protected internal and changing it
to public it will work, even if the property Amount is private set.
So I think that the problem has relation to the Internal restriction.
I don't know why since the function is marked as protected internal
and not only as internal. To give you a clear look I'll write a
similar code here:
public class Foo
{
public virtual decimal Amount { get; private set; }
protected internal void IncrementAmount(decimal value)
{
this.Amount += value;
}
}
public class Bar
{
public Foo Foo = new Foo();
}
Bar mapping:
<many-to-one name="Foo" column="Foo_Id" class="Foo" not-null="true" /
>
var bar = s.Get<Bar>(10);
bar.Foo.IncrementAmount(1);
TESTS RESULTS FOR THE ABOVE CODE:
Modifying the property:
protected internal void IncrementAmount(decimal value);
public virtual decimal Amount { get; private set; } // NOT OK
public virtual decimal Amount { get; protected set; } // NOT OK
public virtual decimal Amount { get; set; } // OK
Modifying the function:
public void IncrementAmount(decimal value);
public virtual decimal Amount { get; private set; } // OK
public virtual decimal Amount { get; protected set; } // OK
public virtual decimal Amount { get; set; } // OK
Modifying the mapping:
<many-to-one name="Foo" column="Foo_Id" class="Foo" not-null="true"
fetch="join" /> // ALWAYS OK - Even with internal
So yes, I think this behavior has relation with the internal
restriction. What do you think?
Thanks
