Since your next question will probably be :
"Is it normal that popups in AUGUIFramework don't automatically update
their menus when the set of value strings for an indexed parameter
changes ?" ;-)
The answer is : Yes.
They don't listen to this property.

Hi Marc,
That helps alot - but what about if the set of value strings for an
indexed parameter changes? Can that be communicated?
Thanks,
Robert.

Something like this will do you:
AudioUnitParameter dirtyparam;
dirtyparam.mAudioUnit = GetComponentInstance();
dirtyparam.mParameterID = _theParameterID_;
dirtyparam.mScope = kAudioUnitScope_Global;
dirtyparam.mElement = 0;
AUParameterListenerNotify(NULL, NULL, &dirtyparam);

Is there any way to signal the UI that parameters have changed? I see
the PropertyChanged() method in AUBase but there's not an equivalent
ParameterChanged(). My backend can change things that affect the
rendering process and I've exposed these as parameters but I'm not
sure
how to let the GUI know. I thought AUBase::SetParameter would do it
but
I don't think it does...
Thanks,
Robert.
