Hi Petemuir, Thank you for Immediate reply. I did what you said but I am getting exception like... No tag "convertEntity" defined in tag library imported with prefix "s" And Now I am using Seam 1.2.1 Do I need to take selectItem.jar and selectItems-ui.jar again. If I don't have correct version Please tell me... Thanx in advance. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4037295#...
