[jboss-user] [JBoss Seam] - NoSuchMethodException when acessing protected methods in sup

[pettersonfp]

Hi,

I having weird NoSuchMethodExceptions that I cannot understand, I made a very simple example that reproduces my problem.  Someone can help me understand what I am doing wrong?

Thanks in advance,
Petterson

Base.java

  | public class Base {
  | 
  | 	protected void printProtected() {
  | 		System.out.println("printProtected");
  | 	}
  | 
  | }
  | 

Derived.java

  | import org.jboss.seam.annotations.Name;
  | 
  | @Name("derived")
  | public class Derived extends Base {
  | 
  | 	@Override
  | 	public void printProtected() {
  | 		System.out.println("DerivedProtectedPrint");
  | 		super.printProtected();
  | 	}
  | }
  | 

testDerived.xhtml

  | <!DOCTYPE composition PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
  |                       "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

  |                 xmlns:f="http://java.sun.com/jsf/core"
  |                 xmlns:h="http://java.sun.com/jsf/html"
  |                 xmlns:rich="http://richfaces.ajax4jsf.org/rich"
  |                 template="layout/template.xhtml">
  | 
  | <ui:define name="body">
  |     
  |     <h:messages styleClass="message"/>
  |     
  |     <h:form id="printTest">
  |     
  |         <div class="actionButtons">
  |             <h:commandButton value="Protected" action="#{derived.Protected}"/>
  |         </div>
  |           
  |     </h:form>
  | 
  |  </ui:define> 
  | </ui:composition>
  | 


And the Stack Trace got when I press the button...
