A component is not a variable, so the variable resolver won't work. You are on the right track with findComponent, but your component id is actually not "datMod". If there is a surrounding naming component (like h:form) your name will be prefixed with that. So, if your form is "id="myform" then you need to look up "myform:datMod". If you have any other naming components, you can take those into consideration too. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3993459#...
