Hi,
I have been attempting to intialize an HB Datastore however I am hitting a Null Pointer
Exception in the computeReferers method of the HbDataStore. The full stack trace is:
java.lang.NullPointerException
at org.eclipse.emf.teneo.hibernate.HbDataStore.computeReferers( HbDataStore.java:742)
at org.eclipse.emf.teneo.hibernate.HbDataStore.initialize(HbDat aStore.java:163)

org.sdmx.registry.persistence.TestHibernateSessionManager.te stTeneoPersistence(TestHibernateSessionManager.java:471)

at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMe thodAccessorImpl.java:25)
at com.intellij.rt.execution.application.AppMain.main(AppMain.j ava:90)
Setup: Teneo 0.75, EMF 2.2, Hiberate 3.2, Java 1.5
Other Info:
Within my setup I am using a hibernate mapping file which I generated with Teneo manually and force
its use through the USE_MAPPING_FILE persistence option.
From tracing through the code it would appear that it is falling over on this line below when it
attempts to get the 'element' from the property value and it is null. The property in question is an
org.hibernate.mapping.List.
throw new HbMapperException("Type "+ ((Collection)prop.getValue()).getElement().getClass().getNam e()
+ " not supported");
regards
Duncan
