Error using dynamic-component with JPA
--------------------------------------
Key: HHH-6639
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6639
Project: Hibernate Core
Issue Type: Bug
Affects Versions: 3.6.7
Environment: MySQL 5.0.1, Java 1.6.0_26
Reporter: Wölfle
Attachments: testJPA.tar.gz
Hi,
there seems to be a bug when using dynamic-components and an EntityManager.
When using hibernate directly, everything works fine. If using the EntityManager, the
following exception is thrown, because for the dynamic attributes no members in the Entity
class exist (which is the intention of dynamic-attributes, as far as I understood them).
Exception in thread "main" java.lang.IllegalArgumentException: Cannot determine
java-type from given member [null]

Attached is a tar.tz file with a sample hibernate project and a junit test that reproduces
the problem.
