jsf <f:selectItems> itemVale and message bundle question

I have a form with a combo box populated like this:

<f:selectItems value="#{prog开发者_如何学GoramHandler.validLanguages}" 
var="languageConstant" 
itemLabel="#{languageConstant.value}" 
itemValue="#{languageConstant}" />

I also have a message bundle defined:

<f:loadBundle basename="MessageResource" var="msg" />

My question is, my problem is the languageConstant.value returns a key from the database, for example LANG_ENGLISH, and I want to display the text value from the message bundle.

How do I do this? For example, I guess I'm looking for something like this:

itemLabel="#{msg.[languageConstant.value]}"

Any help is greatly appreciated!

You're close. It's

itemLabel="#{msg[languageConstant.value]}"
