NHibernate, setting a property to lazy

Post by kindbergs.dk » Sun 27 Jan 2013 21:31

Using Entity Developer for NHibernate version 4.7.313 to generate mappings, when I set a property/database field to Lazy (f.ex. due to that field containing a big blob that I don't want to load when presenting lists), NHibernate add the following to my log4net log:

(date) [8] ERROR NHibernate.Tuple.Entity.EntityMetamodel - Lazy or no-proxy property (name of field) is not an auto property, which may result in uninitialized property access

How do I avoid NHibernate giving this error?
Is there something specific I need to choose in the mapping of the field in Entity Developer, in addition to just changing the "lazy" to "true", to avoid the error?
Or is it a bug in the Entity Developer export to xml files?

Note: I think the lazy part works, but I just want to be sure it works optimally.

Please treat this message as a warning.
NHibernate requires lazy or no-proxy property to be an auto property. The current implementation of our standard templates doesn't allow to use auto-properties because of supporting INotifyChanging, INotifyChanged and other property features. We will investigate the possibility of generating auto-properties by our templates and post here about the results.

Okay, thanks.
It was also my impression that it worked, so from now on I will ignore the 'warning' in my logs :roll:
By the way, thanks for making a really powerful tool - I would not use NHibernate without it!

The behaviour is changed: .NET auto-properties are generated in code if both Property ChangeNotifiers and Property Change Partial Methods properties of a template are set to False. We will post here when the corresponding build of Entity Developer is available for download.
