I did a bit more investigation after learning that the Castle proxy
factory factory is used by default in FNH. When I removed any attempt
to set this myself, that particular problem went away. However, that
exposed a different error, one dealing with a particular ClassMap,
that read "Could not format discriminator value to SQL string of
entity Campaign." I was a bit surprised, because my subclass
discrimination had been working for quite a while. The method call
looked like this:
DiscriminateSubClassesOnColumn<int>("intCampaignTypeID")
.SubClass<InspectionCampaign>(1, x => {} )
.SubClass<OBPCampaign>(2, x=> {});
After some searching about problems with the
DiscriminateSubClassesOnColumn method, I found a couple of instances
where people seemed to be having similar problems (http://
stackoverflow.com/questions/326174/nhibernate-mapping-with-a-class-
hierarchy-whose-base-class-is-abstract-and-the-di and
https://forum.hibernate.org/viewtopic.php?t=974225).
It turns out that when I add a "default" discriminator value to the
method call, everything's hunky dory.
DiscriminateSubClassesOnColumn<int>("intCampaignTypeID", -1)
.SubClass<InspectionCampaign>(1, x => {} )
.SubClass<OBPCampaign>(2, x=> { });
This bothers me a bit, though, because this "default" value doesn't
really exist. All of the values in the database are either 1 or 2,
and the Campaign base class is abstract anyway, so I don't want
NHibernate trying to create one in any case.
Was there a recent change that made this default value necessary? As
I said, the original method call without the default had been working
for a while.
Thanks for all your responses!
