hi, in a form I want to validate that the code asigned in a field is one that already exists. For instance, I´ve a field for currencies. I have a table for them, and I want to check that the currency filled is already on the database to avoid foreign keys problems. I´ve found 2 solutions. The first is to override persist method and there by means of a query to check if that value is ok. The second is to add a try-catch in the persist, and in the catch check if there has been an Exception like this org.hibernate.TransientObjectException: object references an unsaved transient instance - save the transient instance before flushing:... Is there a better "seam-way" of validating this? thanks in advance! View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4107970#...
