Build Identifier: 2.2.0-RC4 In case deriving an entity by another entity that contain to different projects, generating the metamodel results a NullPointerException. In order to build the projects maven is used. --- When using 2.1.2 the metamodel is generated incorrectly. The reference to the parent entity does not exist in the child entity. But there is no NullPointerException when generating the metamodel.
