Calling Service::Remove will not raise the Service::PropertyChanged event

Calling Service::Remove will not raise the Service::PropertyChanged event

[Andrei Datcu]

I'm having a wifi service with:
State == "idle"
Error == "invalid-key"

Calling Service::Remove() will correctly reset the "Error" property.
There will be no Service::PropertyChanged signal emitted however. Is
this a bug or is this technically not considered a property change
since the property is now missing all together from the property set?

Thanks,
Andrei Datcu

Good question. I tend to say, the reason why no PropertyChanged is
issued is that the service itself is removed and not just a
property. Given that you call 'Remove' and get a reply message which
says, it the request was either successful or not should be
enough. Also, the D-Bus service object should be removed then and
this should give another signal source.

Thanks,
Daniel
