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:

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?

Post the whole exception. You need to mark any @Converter's @BypassInterceptors and you can't make them EJB3s - so, in essence, no.
