  simulate(document.getElementById("gwt-debug-cwCustomButton-toggle-normal"), "mouseover");

simulate(document.getElementById("gwt-debug-cwCustomButton-toggle-normal"), "mouseup");


  In my application the fireEvent fails,
because GWT's $wnd.event is null. (Line: 117,

  If there is no way to simulate the click with plain JS,
then is there a way to use GWT's EventDispatcher
to simulate the click?

I think you can move any part of you project to another

For example it is possible to move or copy-paste a class
  from the client code to the serve code.
Isn`t it ?

  Please re-read my previous mail, and possibly go read
the documentation at http://www.gwtproject.org/doc/latest/DevGuideServerCommunication.html
  RpcService, HybridServiceServlet and ClientOracle
were part of "Direct-Eval RPC" (aka deRPC), which was
experimental and discouraged for use in production.
  deRPC has been removed in 2.7, but GWT-RPC is still
there. deRPC and GWT-RPC are (were) two different
things; deRPC aimed at being a "better GWT-RPC" and
replacing it, but it failed, so GWT-RPC is still there
and deRPC has been retired.
  
  
  Migrating (back) to GWT-RPC should hopefully be as
easy as switching RpcService and HybridServiceServlet
(and/or RpcServlet) to RemoteService and
RemoteServiceServlet respectively; and remove the
 from your
gwt.xml.
  You're talking about ClientOracle though, which means
you possibly had some customization on top of the
"out-of-the-box" deRPC, so migration *might* not be that
easy (depending on the kind of customization you have).
  Last, but not least, there must have been a reason to
use the experimental deRPC over standard GWT-RPC, so
