This is with Hibernate 3.0.5.

I do a Hibernate query, get a class "Rating" from the database. That works fine. Then I get a strange exception during a very basic property set:

Code:
rating.setRatingDate(new Date());


The exception stack looks like:

Code:
Hibernate: select rating0_.UserID as UserID0_, rating0_.RatableItemID as RatableI2_0_, rating0_.OriginalRating as Original3_5_0_, rating0_.NormalizedRating as Normaliz4_5_0_, rating0_.RatingDate as RatingDate5_0_, rating0_.Enabled as Enabled5_0_ from Ratings rating0_ where rating0_.UserID=? and rating0_.RatableItemID=?

How does the Hibernate code intercept my property set method? I don't even know where to start debugging.

Any ideas?

I recommend that you apply the suggestion in the trace and set
Code:
hibernate.cglib.use_reflection_optimizer=false

in your Hibernate properties. Then you will hopefully get an error that is easier to understand.

I added to hibernate.cfg.xml:

Code:
<property name="hibernate.cglib.use_reflection_optimizer">false</property>


Still simliar error:

As per the docs, it is a system-level setting and must be applied using hibernate.properties.

I thought that you used either hibernate.properties or hibernate.cfg.xml. From the docs:
Quote:
For Hibernate's configuration, we can use a simple hibernate.properties file, a slightly more sophisticated hibernate.cfg.xml file, or even complete programmatic setup. Most users prefer the XML configuration file


You are saying that some options required the use of the hibernate.properties file? Can I set this one option programmatically?
