dynamic key generation with EL

[Michael Heinen]

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.   The following sample does not work: <t:dataList var="myVar" value="#{MyBean.myList}">                          <h:outputText value="#{msgs['myApp.prefix.'+myVar.value]}"/>   Thanks for any help Michael
