Hi,

it's not clear to me where you are trying to call item.payload<..>(), but if 
you are calling it on an Item you get as an argument in itemAdded()/
itemChanged() in your Resource, you must make sure you have the correct 
ItemFetchScope set, i.e. in your Resoure constructor you have to add

changeRecorder()->itemFetchScope().fetchFullPayload(true);

otherwise the Resource will only retrieve Items with the elementary metadata 
without the actual payload. Note that in itemRemoved() calling 
item.payload<...>() will always return a null pointer, because by the time 
itemRemoved() is called in your resource the Item no longer exists in Akonadi 
and so the payload cannot be provided.

If you are retrieving the Item manually via ItemFetchJob (be it in your 
resource or in an application), you have to do the same thing, i.e.

job->itemFetchScope().fetchFullPayload(true);

There are more options you can set in ItemFetchScope (there's also 
CollectionFetchScope btw). If you ever feel like the Items or Collections you 
are being given don't have all the information you would expect them to have, 
check if the fetch scope is correct.

Cheers,
Dan
