Nope, that also concerns balances (or any request for that matter), since some 
protocols do not allow to specifically request the balance (e.g. EBICS) but 
rather return the balance with the transaction statements (e.g. in the SWIFT 

So when requesting the balance you must also be prepared to import the whole 
imexporter context.

That's why I propose a single importation point between the application and 
AqBanking. It simplifies the design dramatically, and since you already have 
the interface for importing an ImExporterContext (->SWIFT MT94x importer) it 
would be easiest to use *that*.

Any request send to a bank returns its resulting data in the imexporter 
context, so it would be easiest to:
- create the corresponding job
- send it to the bank via AqBanking, passing it the ImExporterContext to use
- check for the status of the job
- import the ImExporterContext

That's how I do it in QBankManager and how it's done in the KMyMoney plugin 
and it works rather nicely.

Right, but since GnuCash is setting standards when it comes to financial 
applications I don't think it should allow for the user to loose important 
data :-)
