Hi, You can look to LazyMap from org.apache.commons.collection. Is very ease to use together with transformer.

No, I don't think it would work. option would be two use a double-indexed map (you'd have to change to an implementation of map which returns a map then, and this map would get the second argument passed in). your example changed to the new approach: <t:dataList var="myVar" value="#{MyBean.myList}"> <h:outputText value="#{msgs['myApp.prefix'][myVar.value]}"/> regards, Martin On 10/16/06, Michael Heinen <[EMAIL PROTECTED]> wrote: Hi, I have to create a message key dynamically in JSP. How can I do this with EL and concat expressions? I have the prefix 'myApp.prefix.' and want to add a value at the end.
