Is there something new when you connect a Cocoa UI to an Audio Unit plug in?

Hi,

With the help of Stephan, I could create AU with the Lion new system. I wanted to create a Cocoa UI using the same methods than before. It does not work : the plug is built, but the Cocoa UI does not appear in AULab or in GarageBand.

This method is not accepted by the compiler :
void ParameterListenerDispatcher (void *inRefCon, void *inObject, const AudioUnitParameter *inParameter, Float32 inValue)
(in CocoaView class)

I've got this warning :
"No previous prototype for function ParameterListenerDispatcher"

Was it a function inside AUDebugDispatcher? I do not find a corresponding one in AUPlugInDispatch.

In Console, I verified that the bundle of the CocoaUI was found, but not the class CocoaViewFactory. Would someone have an idea?

Thanks!

Hervé

Note : there's no template to create an AU plug in XCode 4.2. In 4.3 maybe?
