Hi all, I'm working with seam and jboss since a few weeks. Now I'm trying to fill a selectOneMenu with an object using <s:convertEntity /> The problem is, I want to submit that form containing the selectOneMenu and save it in the database. As I click on the submit button the jboss server does something, and I mean something! It doesn't write an error message or anything else, the only response I got is from the <h:messages showDetail="true" /> component. I only got the german message but it's something like: "Validation error _id35: Value is no valid selection" Would be cool, if anyone could help me. I'm trying to fix this problem since a few days and it's becoming frustrating now. Thanks, Kim View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4080392#...
