The very first thing I do is call the default implementation (AUBase::RestoreState and AUBase::SaveState). BTW, none of these methods (Restore or SaveState) are even called by the AU Validation tool...

Marc, I am afraid that you are more guessing then knowing, but your quick reaction and your right use of the terminology gives most developer here the impression that your answers are right and that looking into this isn't necessary.

If neither property is set/get, no savestate/restorestate is called, how can the AU Validation tool possibly check for any changed names?

Regards,

Hi all,

I still get the "WARNING: Preset name is not retained in retrieved class data" although I don't even have ANY presets! My plugin has no presets whatsoever, only a state which is retained perfectly via my SaveState() and RestoreState() implementation.


Except that clearly it's not perfect. It's not retaining the preset name part of the state data. I'm not sure how you're doing things, but personally I think it's easiest to just let the default implementations in AUBase handle things (they do it all correctly), and then if you need to override those in order to add your own stuff, begin by still letting those do their thing:


    ComponentResult result = AUBase::RestoreState(plist);
    if (result != noErr)
        return result;
    ...etc...

Something like that.



No property "CurrentPreset" or "PresentPreset" is ever passed to my "GetProperty" or "SetProperty" methods.


They are caught and handled by AUBase::DispatchGetProperty().
