| Customizing EMF context menu [message #1751228] |

I want to customize context menu bases on EditingDomainActionBarContributor. Namely, I want to hide such context menu items as cut/copy/paste for some pages of an editor. What is the best way to do this?
I've looked into generated ActionBarContributor classes, and see that all actions are created programmatically. Can I contribute new actions using plugin.xml?
Also I'm a little bit confused about enabling/disabling cut/copy/paste and delete commands. I tried to override createRemoveCommand() to always return UnexecutableCommand, but this method never get called.

There are various ways to contribute to menus via the plugin.xml. The older approach, using actions, is to use the org.eclipse.ui.popupMenus extension point. The newer way, using commands and handlers, is to use the org.eclipse.ui.menus extension point.
