MM> public String action(String myparam) {}

MM> public void valueChangeListener(String myparam) {}

Thanks.  Now I understand your request.

MM> I already got mail by Kin-Man - he said this won't be included, we

MM> This effectively means we cannot use the new EL functionality to solve

MM> valueChangeListeners in a dataTable), and therefore, even though we
MM> can get rid of the f:setPropertyActionListener, we would still need an
MM> f:setPropertyValueChangeListener - a pity.

I agree that the feature you request is indeed valid.  Can you please
file it in the uel.dev.java.net issue tracker?
