[jboss-user] [JBoss Seam] - component with multiple interfaces?

[alex.x.zhang]

My question is: can you use one component with multiple interfaces for multiple purposes?

I am trying to use one class as both the backing bean and the selectItem converter, like this: 
@Stateful
  | @Name("fooManager")
  | @org.jboss.seam.annotations.faces.Converter
  | public class FooManagerBean implements FooManager, javax.faces.convert.Converter{
  | 
  | }
  | 

  | <h:selectOneMenu ... converter="#{fooManager}"></h:selectOneMenu>
  | 

But at run time I got this exception:

anonymous wrote : Cannot convert FooManagerBean:3j011-5hrmn-fcfnjsws-1-fcfnlgsp-13 of type class org.javassist.tmp.java.lang.Object_$$_javassist_6 to interface javax.faces.convert.Converter

I think this is neat because the converter and the backing bean are all together so there is no need to pass data around and no synchronization issues. 

Is this possible?
