> Noticed that the Map-wrapper classes (org.apache.struts2.dispatcher.RequestMap etc.) returns the new value from put-method.
> request.setAttribute(key.toString(), value);
> return get(key);
> Should be:
> V value = get(key);
> request.setAttribute(key.toString(), value);
> return value;
> in order to be consistent with other Map-implementations.
