Hi everyone,

I am currently developing an RCP based on Eclipse 3.6. The application is based on "org.eclipse.ui.ide.workbench". I am currently failing to enable the entries for "Save, Undo and Redo" in the main menus. Whatever I do they stay grey. I wrote three commandHandlers for:

org.eclipse.ui.file.save
org.eclipse.ui.edit.undo
org.eclipse.ui.edit.redo

Using the same commands in a different popup-menu works fine and they are correctly enabled and disabled. Nevertheless for the main menu they always stay grey.

For the commands:

org.eclipse.ui.edit.cut
org.eclipse.ui.edit.copy
org.eclipse.ui.edit.paste

everything works fine and i get the same behaviour (enabling and disabling) for both menus.

Does anyone have similar problems or does anyone know how to handle this?

Cheers

Phil

Hi Phil,

Try this in your ApplicationActionBarAdvisor.makeActions(IWorkbencWindow):

register(ActionFactory.PASTE.create(window));

etc ..

I'm not sure exactly what it does. I have a vague idea of it connecting the
global action to the command framework.

Regards,

Wim
