Hi, Gavin, thanks for the response. I should have taken in account the time zone difference long ago and write my posts only at night so that someone can see them in the US at a normal time. I think you're not talking in the same scope as I do so there is a little misunderstanding. #{sel.label} - can be evaluted because this is all happening inside ui:repeat and sel is an item from the collection returned by localeSelector.supportedLocales Please refer to initial post if something is left out uncommented. I cannot repost the hole thread here. action="#{localeSelector.selectLanguage(sel.value)}" I do not want sel.value evaluated on post back. But this is what Seam does with a MethodBinding. I want sel.value to be evaluated in the first request so that on postback Seam will have to evaluated the valid code: action="#{localeSelector.selectLanguage('de')}" //for example PS I can be wrong in not spending enough time on the manuals. You can be wrong on not spending enough time on my question. I have written my question for the 5th time probably. I'll get bored too, eventually :) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4067576#...
