use of UIXCommand.addReturnListener -- or -- adding ReturnListener dynamically

[Arie Morgenstern]

I am trying to add a ReturnListener to a RichCommandButton in Oracle ADF. RichCommandButton inherits the method addReturnListener from UIXCommand. It also has getReturnListener and setReturnListener. But, I just cannot get it to work.

Does anyone have any experience with this?
I am not sure the direction I should take to dynamically create and add a ReturnListener to a CommandButton.

If you do not have any suggestions for the above, possibly you could help with this:
I have an inline class, as pasted below:

    public class RListener implements ReturnListener {
        public void RListener() {
        }

        public void processReturn(ReturnEvent event) throws javax.faces.event.AbortProcessingException {
        }
    }

It compiles. But, when I run it, I get this:

<StateUtils$Saver> <restoreState> 
java.lang.InstantiationException: com.view.backing.Main$RListener
	at java.lang.Class.newInstance0(Class.java:340)

Any help would be appreciated, because I'm alittle over my head.

Thanks,
Arie
