Post to account in post dialog vs payment dialog

[Geert Janssens]

Both the Post... dialog and the Payment dialog have a field to select an 
account to post the invoice resp. payment to.

In my experience for a given invoice and it's associated payments, this should 
always be the same account. For a different invoice with it's associated 
payments, this could be a different account.

Also should you post an invoice to one A/P and its payments to another A/P, 
GnuCash will not consider this invoice as paid.

Do you know of any use case where this would not be the case ? I mean are 
there use cases where you
* create an invoice,
* post it to A/P 1
* and post the payments to A/P 2

If not, I see an opportunity improve GnuCash' intelligence. If so, then we 
should fix GnuCash that is knows the invoice is paid even when the payments 
are posted to a different A/P than the invoice.

Most users will probably never hit this issue, as you need to have more the 
one A/P account to see it.

I have 3 different A/P accounts. Most invoices are posted to A/P 1, and some 
are posted to A/P 2 and A/P 3.

As things stand now I always have to remember which A/P account I posted the 
invoice to in order to select the proper one when I pay it. If I select a 
different A/P account for the invoice and it's payments, the invoice never 
gets the status paid.
