I am trying to do a one-to-many mapping of a DocumentType class that contains a collection of FiedTypes. However I get the exception below if I don’t include all the mappings in the same hbm.xml file. Do I need to provide both class mappings in the same file for this to work? Can I not have a separate DocumentType.hbm.xml file and a FieldType.hbm.xml file?
