JSF lower case EL

[nico.ben]

Hi, I am struggling finding a way to get a lowercase string from a component property-
Status is an ENUM and _inv.status is Uppercase. I want it lowercase, because css style are in lowercase.

<h:outputText value="#{messages[_inv.status.key]}" styleClass="#{lower(_inv.status)}" />


Can you give me an hint, please?

Bye
Nic

I forgot to write that the previous form gives me:

Caused by: javax.el.ELException: Function ':lower' not found

This should work..

#{_inv.status.toString.toLowerCase()}
