    I am currently getting a strange exception when trying to commit some
    objects to the db. I'm hoping someone here can help me figure it out.

    org.apache.cayenne.CayenneRuntimeException: [v.3.0-SNAPSHOT May 16
    2008 12:28:23] Can't extract a master key. Missing key (id), master ID
    (<ObjectId:MyDataObject, TEMP:001A1A0065510101>)

           at org.apache.cayenne.access.DataContext.commitChanges(DataContext.java:1066)

    Any idea what this means? I'm using some 1:1 mappings on the PK of
    this table, and also some cayenne inheritance, so it's possible I set
    something up wrong.
