Cocoa Bindings: binding each menu item of a NSPopUpButton, so that it can be enabled/disabled individually

It’s been a very long time since I’ve working with Cocoa Bindings, so my knowledge isn’t very fresh.

I am trying to connect up a NSPopUpButton so that each menu item can be enabled or disabled separately. I have connected up the content binding to an array controller that has two properties: localizedName and enabled. These represent the names and enabled status of each menu item that will be shown.

I’ve also connected up the contentValues binding so that it is bound to the arrangedObjects.localizedName property.

Now I’m stumped. There is an enabled binding but it seems to connect to the entire popup button, not the menu items.

Is there a way to connect to the enabled property of each individual menu item? in the same way as is possible with NSTableView?

Thanks in advance.

Frank

Just for posterity: While I haven't found out how to link to the enabled attribute of the popup menu button's NSMenuItem, I have found out that NSPopupButton does not handle disabled menu items anyway.. it just does nothing. The state and the hidden attributesboth work fine, however, so I ended up just hiding the non-selectable entries via theNSMenuDelegate` instead.
