[jboss-user] [JBoss Seam] - using <s:div rendered="..."> instead of <s:hasRole>

[asookazian]

JBoss 4.0.5
SEAM 1.2

is it possible to call a method on a SLSB as follows?:

<!-- in place of <s:hasRole> restriction -->
<s:div rendered="#{authenticator.display}">
       <s:button view="/CustomersEdit.xhtml" 
	                    id="edit" 
	                 value="Edit"/>
</s:div>

display is a method that returns true or false after evaluating user's role (access level) for that component/page.

I'm getting the following stack trace:

javax.faces.el.PropertyNotFoundException: /Customers.xhtml @92,46 rendered="#{authenticator.display}": Bean: org.javassist.tmp.java.lang.Object_$$_javassist_79, property: display
