Hi,

I have a special stuation that I need to map one property into two columns. Is it possible? I've tried this mapping:



But received this error:

org.hibernate.MappingException: Foreign key (FK6B08A21A2E6A76F6:OCORRENCIA_SUBTRANSMISSAO [COD_CLASSE,COD_TIPO_OCORR])) must have same number of columns as the referenced primary key (CLASSE [COD_CLASSE])

This error is not because of mapping 2 col into 1 property. Check the <set> and/or the <id> of the parent class. That also should have same number of columns as of this <many-to-one tag>.
Also i found that the order in which you put this column in the set and many-to-one tag matters.
When i tried to reverse it my join came wrong.

Hope this helps.

I solved the problem creating a new <one-oto-one> tag...

Thanks!
