hi,
I have a one to many association setup as a parent child relationship. The many side maybe populated at any point in time. If I execute a getCriteria operation based on the primary key on the parent before I populate the child table I get the following error:

org.hibernate.PropertyAccessException: exception getting property value with CGLIB (set hibernate.cglib.use_reflection_optimizer=false for more info) getter of com.siVault.siForms.BusinessObjects.FormPage.?

Is there a way for it to ignore if the collection is empty or null?

Thanks,
