Hi, tnx for the solutions. I already implemented it with no 4 (action + navigation rules), but it would be more user friendly to use the richFaces dropDownMenu component (i've seen the demo on exadel's site). However, when I try to use it on a page, I get this error: anonymous wrote : <rich:dropDownMenu> Tag Library supports namespace: http://richfaces.ajax4jsf.org/rich, but no tag was defined for name: dropDownMenu I'm using Seam 1.2.1 and a seam generated project, with the default libraries. Is this a new developed component from richFaces? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4047936#...
