[hibernate-dev] Replacement for SessionFactoryImplementor#getClassMetadata ?

Hi all, Hibernate Search is using this method, but it's deprecated with the following comment: "Use the descriptors from #getMetamodel() instead". I'm a bit lost about how to reach the same by using the Metamodel. I found this solution: SessionFactoryImplementor sfi =.. ClassMetadata cm = (ClassMetadata) sfi.getMetamodel().entityPersister( x ); But it's requiring a suspicious casting, which I was hoping to avoid as I'm already working at SPI level? My goal is to ultimately read `ClassMetadata#getIdentifierPropertyName()`. Maybe there's a better approach? Thanks, Sanne
