Hi Fabio. Thank you for responding so quickly.
The truth is that what you say makes sense, but then I guess that Hibernate should take note that if all properties are null the corresponding record in the database should not exist. The problem is that the record is always created, even when the properties contain null values. Therefore when you try to remove the entity an error ocurs because there is a relationship in the database. I'll try to do something with what you said. Thank you very much!
