[jboss-user] [JBoss Seam] - validation and persisting

Hi, I have problem with validation on the server side. Let's imagine I change data on the web form and submiting. On the call I decide that combination is wrong and add message to the FacesMessage and return null. But problem is, that some changes are saved to the database. Have I to throw some exception or I have to return null only ? Thanks Mila View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4074163#...
