Dennis is confused. He didn't realize that Facelets supports JSF EL
functions. [MyFaces can also support these, but it's tricky to get
them installed (subclass ValueBindingImpl).]
You definitely want to be using #{}.
It's been awhile since I've used myfaces and facelets user-defined EL
functions, but they should work fine. (I primarily needed a
jstl:length function, which is automatically available in facelets).
Is your function static? That's a requirement. Did you include
your taglib file in facelets.libraries in the web.xml file?
I'd recommend asking your question on the facelets mailing list --
there's nothing specific to MyFaces on using facelets user-defined EL
functions.
I had used #{}. Now I tried ${}, which doesn't work either.
The xhtml file:
<ui:component xmlns:ui="http://java.sun.com/jsf/facelets";
xmlns:h="http://java.sun.com/jsf/html";
xmlns:f="http://java.sun.com/jsf/core";
xmlns:t="http://myfaces.apache.org/tomahawk";
xmlns:le="http://www.prosystemsit.de/le";
>
<h:outputText value="${le:wert('test')}" />
</ui:component>
The Taglib file:
<!DOCTYPE facelet-taglib PUBLIC
"-//Sun Microsystems, Inc.//DTD Facelet Taglib 1.0//EN"
"http://java.sun.com/dtd/facelet-taglib_1_0.dtd";>
<facelet-taglib>

Are you using ${} or #{} ? User defined functions only work for JSP EL.
Sorry.
