Right, but we have a misunderstanding here.
I am talking about KCal::ResourceCalendar, i.e. the calendar equivalent to 
KABC::Resource.

In the KABC one I only read/write from/to Akonadi when load() or save() (or 
their async variants) are called, i.e. strict load/save behavior.
I think this is what applications using KABC::AddressBook expect the resource 
to do, at least kabcclient does :)

Since this is the first time I am actually working with the KCal API, I tried 
to implement it the same way, i.e. read/write from/to Akonadi in doLoad() and 
doSave().
When testing with KOrganizer it seems that adding or changing an incidence 
results in doSave() (the variant with the incidence parameter) being called, 
however when I delete one, the normal doSave() does not seem to be called.

Cheers,
Kevin
