Hi,
a call to componentHandler::restartComponent(kParamTitlesChanged| kParamValuesChanged) will only trigger the host to invalidate its caches for the parameter titles and values. It will not send parameter changes to the processor in its process function and it will not deactivate and activate the processor.
One question for Erez:
What do you expect to happen in the host when the user of your plug-in triggers the action and the host is in write automation mode for your plug-in?
Cheers,
Arne
