I've got a pretty simple entity that has one lazy-loaded property (a
large string). I want to change the values of two other properties on
the entity and save the changes to the database. I don't need the
value of the lazy-loaded property at all for this process.
Unfortunately, NHibernate does not seem to issue an UPDATE statement.
If I set the property back to normal, non-lazy loading, the UPDATE is
issued correctly. If I actually use the value of the lazy loaded
property before commiting, the UPDATE is issued correctly. Is there
something I'm missing with the way lazy loaded properties work? I'm
using NHibernate 3.2 and FluentNHibernate 1.3.
Class:
public class MyClass {
public virtual int Id { get; set; }
public virtual string BasicProperty { get; set; }
public virtual string EmailContents { get; set; }
public virtual OtherClass ReferencedItem { get; set; }
public virtual void DoAction() {
BasicProperty = "New value";
}
}
Mapping:
class FeedbackLoopEmailMapping : ClassMap<FeedbackLoopEmail> {
public MyClassMapping() {
Id(x => x.Id, "MyId").GeneratedBy.Identity();
Map(x => x.BasicProperty);
Map(x => x.LazyLoadedProperty, "LLPDatabaseFieldName").LazyLoad();
References(x => x.ReferencedCollection, "ReferencedCollectionId");
}
}
The consuming code opens a session with a transaction, calls
'DoAction' and then commits. Thing is, I'm updating a property in an
unrelated entity and that change issues an UPDATE no matter what...
Thanks,
Andrew
