I realize there are many similar questions, but none have helped me along on this.
I'm using a CRUD framework called Tynamo, which in turn relies on Apache Tapestry and Hibernate. This all works fine, except for when I try to use it for CRUD on a table with a composite/compound primary key.
I've decided not to go the @EmbeddedId route, since it seems to not work at all with the framework. That being said, I have been using the @IdClass method, which is mostly working; I think I'm a line or two of code away from success.
The issue is that when it starts using reflection to build the objects, it blows up and says, org.hibernate.InstantiationException: No default constructor for entity: ..., even though there is, indeed, a public, empty constructor for that inner class.
When answering, please avoid code snippets, and use full classes, etc. so that others visiting this thread can have a more complete picture of what's going on.
