I am adding a EventListener to a Component as follows:

<window id="y" width="100%" visible="false"> <zscript>
import com.potix.zk.ui.*;
import com.potix.zk.ui.event.*;
void registerEvent(Component c){
EventListener listener=new EventListener(){
public void onEvent(Event e){
}
public boolean isAsap(){
return true;
}
};
//System.err.println(c);
c.addEventListener("test", listener);
}
</zscript>

<groupbox id="z" mold="3d" width="100%" onCreate="registerEvent(self)"> <caption label="a"/> </groupbox> </window>

the following error is encountered, c.addEventListener("test", listener); is causing it. not sure why? thanks for the help.
