[jboss-user] [JBoss Seam] - Re: @RequestParameter issue

I think there's a little misunderstanding... indeed, the conversion is working just fine when I do: /app/somepage.xhtml?id=1 which is convertible (by parseLong() I guess) to Long and therefore assignable to this field: | @RequestParameter("id") | private Long id; | However, my problem is with something like this: /app/somepage.xhtml?id=a Now, a NumberFormatException is raised in the convertor. I would like to gracefully fail (display a nice error message or something). The question is whether this is possible (without explicitly doing the conversion my self) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4042051#...
