------------------------------------

I would like this be an additional Lazy Fetching constant.

> The method AbstractEntityPersister.initializeLazyProperty(..) load all lazy properties when it's called. It would be great if could only load the requested property.
> I think the only change we need is in AbstractEntityPersister.initializeLazyPropertiesFromDatastore(...) and AbstractEntityPersister.initializeLazyPropertiesFromCache(...). We must change them in a way that only the referenced property is loaded.
> After that, we must change AbstractFieldInterceptor.intercept(..) to update in a better way the unitializedFields collection (I mean, removing the actual property only instead of null it).
> Besides. Why in line 777 to 780 a query is executed? I think it isn't necessary.
> Thanks.
