Thanks Kyle,
Unfortunately the standard paste: selector is used extensively elsewhere in my app, so this simple solution would not be so simple. This is an otherwise very self-contained modal dialog that doesn't have much to do.
I solved it as follows:
My window controller, which is the window's delegate, implements -windowWillReturnFieldEditor:forObject:. I return a subclass of NSTextView which overrides -paste: and adds a property, -pasteDelegate: which I set to be the window controller. (I believe the FE's nextResponder is usually also the windowController, but I wasn't entirely sure I could rely on that, so I just added an extra property to hook it up). Then I just punt -paste to the -pasteDelegate (and also -validateMenuItem for that action).
Works great. In conjunction with some text editing delegate methods I have excellent control over the text fields and the subclassing was absolutely minimal.
