Hi,
for "old" retargetable actions, there were the option allowLabelUpdate and
an action could set another label for its menu item (as example).
Is there a similar function for the new menu contribution mechanism
(org.eclipse.ui.menus) and command handlers? So, that the active handler can
add additional info to its menu item label?
Thanks,
Teddy

Hi Paul,
It is a toolbar button and the default handler. The handler object is
created and the method #isEnabled() is called via HandlerProxy#isEnabled() .
It seems, it is not updated, after the proxy loaded the real handler?
Ciao,
Teddy
