Problem with multiple ids for entity class

[mibo]

When using multiple ids in an entity class (in combination with JPA) this entity can not be found.
Example class: org.apache.olingo.odata2.janos.processor.ref.jpa.model.Photo
Example link: http://localhost:8080/JpaScenario.svc/Photos(Name='Medium%20picture',Type='PNG')
results in:

{"error":{"code":null,"message":{"lang":"de-DE","value":"Die angefragte Entität wurde nicht gefunden."}}}
