Hi,

I'm currently doing some test with custom taglib and I didn't
understand why I'm getting the following error message :

javax.servlet.ServletException: /WEB-INF/tags/buttons.tag(4,0) D'après
la TLD, l'attribut value n'accepte aucune expression

here is my tag :
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f"%>

<h:commandButton id="btnIndex" action="goIndex"
value="${pageScope.aValue}" />

and here my taglib :

<?xml version="1.0" encoding="UTF-8" ?>
<taglib xmlns="http://java.sun.com/xml/ns/j2ee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <tag-file>
        <name>test</name>
        <path>/WEB-INF/tags/test.tag</path>
    </tag-file>
</taglib>

any explanation would be really appreciate :)
