Paul,

If a host does not get a valid bundle path, or cannot load the factory class, you should probably fall back to the generic view or Carbon View (if present). Does the plugin you are describing pass validation? I would assume that it wouldn't.

we recently came across a plugin which claims to have a Cocoa UI (i.e.
GetPropertyInfo indicated that kAudioUnitProperty_CocoaUI was non-zero
in size) but unlike every other plugin we've encountered so far, it
returns a null factory class name.

i've modified the code to fallback on the carbon GUI which is also
provided, but is it really possible for the factory class name to be
somewhere other than mCocoaAUViewClass[0] ?
