http://localhost:8080/metamer/faces/components/richDropTarget/simple.xhtml

Attached Facelets error page (exception.html).
The problem is that clientId is null in the following condition:

public boolean invokeOnComponent(FacesContext context, String clientId,
ContextCallback callback) throws FacesException {
if (null == context || null == clientId || null == callback) {
throw new NullPointerException();
}
...
