Hello, I am currently working with JSF and Portal but I have a lot of problems with JSF ! Does it work differently in portlet ? For example, I wanted to use the h:selectManyListbox but when I submit my form the validation doesn't work ! JSF says : "Value is not a valid option" all the time ... But the same code works fine in a simple web app ! What's the problem ? Thanks by advance View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3972299#...
