Any connection you make from a table cell view to something outside of the table column is suspect. It probably doesn't work.
The views "inside" of a table column are actually in a sub-NIB. There's a NIB archived to a data blob that's embedded in the NIB holding the outline view. That NIB is unarchived and loaded by the table/outline view in its -makeViewWithIdentifier:owner: method. The owner is whatever you pass to that method. (If you let the table/outline view create views without its delegate being involved, it will pass its own delegate as the owner.)
When that sub-NIB is loaded, it contains just its own objects. None of the other objects from the outer NIB. The menu is presumably in the outer NIB, not the sub-NIB. So, the cell views won't be able to establish their connection to the menu.
One exception is the File's Owner placeholder. A connection to that works, but may give a different result than you expect. The File's Owner for the sub-NIB is the owner passed to -makeViewWithIdentifier:owner:. It's not the owner of the outer NIB.
You will need to connect the menu programmatically, most likely in your delegate's -outlineView:viewForTableColumn:item: method.

When I (right) click on a cell outside the two views the contextual menu appears. When I click on one of the two fields it does not. I can see from the logs that the menu delegate's menuNeedsUpdate: is not called in this case. I tried setting the same menu as the menu for these views in IB with the same result. I get the same behavior when I implement -menuForEvent:(NSEvent *)event for my NSOutlineView subclass instead of setting the menu in IB.
