Well, the retrieveItem() method of the resource is only called if an client 
application tries to access the item next time after clearPayload() had been 
called by the resource. Otherwise the request of the client application would 
be responded with the cached value from the Akonadi storage.
So using clearPayload() won't inform other client application that the payload 
has been changed. For that you have to use ItemModifyJob instead as suggested 
by Kevin.

Ciao,
Tobias
