Thanks for taking the time. Does this mean that there's no way to add
items to a menu once it is created? Or only while it is seeable? In this
case we really had to recreate the menus.

The problem is that, in order to provide full SWT functionality (RAP),
we have to make an AJAX request when the menu is about to show and ask
the server for items to add or remove. Before we get the response, we
show only one preliminary menu item (setting display to false for the
others).
Is there a chance that hot adding / removing items from menus will be
possible in future versions of qooxdoo? Otherwise I'm afraid we have to
rewire the whole menu show / hide / cascade logic...
Thanks,
Ralf
