I followed the tutorial at http://blog.eclipse-tips.com/2009/03/commands-part-6-toggle- radio-menu.html to add some radio buttons (as submenu of a pulldown button) to a views toolbar.
I added the handler programmatically by using the IHandlerService.
Everything works fine (the handler is called correctly and has the correct state), but the UI is not updated (the appropriate menu is not marked).
How do I update the UI? HandlerUtil.updateRadioState doesn't seem to update the UI, nor does a commandService.refreshElements call afterwards.
