Description Raghuveer CLA 2009-07-03 11:15:46 EDT 
In our application we have multiple editor opened. We would like to have only single instance of each editor. But "New Editor" popup menu item options is bringing up another instance of the same editor.

  Is there any way to disable either the menu item or to have single instance of the editor at any point in time.

Sorry, this is currently not possible. You can try to support more than one instance of an editor, or if that is not an option, perhaps you are willing to contribute a patch to add this feature?

Hi,

I just managed to disable the "new editor" action within Galileo by creating a handler for command "org.eclipse.ui.window.newEditor".
The handler is active for my editors but never enabled 
=> expression: activeWhen/activePart/instanceof(my editors)
=> expression: enabledWhen/count/value -1

This allows disabling the command for your editors, but not for standard text editors.

Maybe Paul can tell if this might be the correct way to go currently.
