"pete.muir(a)jboss.org" wrote : #{invalid} and #{required} are variables available inside s:decorate, and are booleans. required evaluates to true if you have set the decorated component required, and invalid evaluates to true if a validation error occurs. Could you please point to documentation where these variables are described? I can't find that in Seam reference. It contains examples with these variables, but not full list of variables with descriptions. Thanks ! View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4057574#...
