I created a Model and generated source and schema using CayenneModeler without any problem. Next a wrote a simple test using eclipse 3.x and when I message dContext.commitChanges(org.apache.log4j.Level.ALL); I get the following exception.

java.lang.NullPointerException
        at org.objectstyle.cayenne.CayenneDataObject.validateForSave(CayenneDataObject.java:575)
        at org.objectstyle.cayenne.CayenneDataObject.validateForInsert(CayenneDataObject.java:700)
        at org.objectstyle.cayenne.access.ObjectStore.validateUncommittedObjects(ObjectStore.java:937)
        at org.objectstyle.cayenne.access.DataContext.commitChanges(DataContext.java:1260)

Is this a model issue or a configuration issue? My classpath looks like C:\eclipse3\workspace\MyProject\build;C:\eclipse3\workspace\MyProject\libs\cayenne.jar. I copied cayenne.xml and my map into ...\MyProject\build.
