storing blobs from reports

[Paul J Stevens]

Hi all,

I'm working on this custom module for generating reminders on overdue
payments of invoices.

All is fine. Just one thing bothers me. When I generate the report, I
want to store the last-sent reminder on the party.

I'm using the same pattern used in account_invoice/invoice.py [1]
and I do see the UPDATE query going out to the database. But then, a
ROLLBACK is issued. So what gives? Do I need to wrap this in a
transaction? Can I prevent the ROLLBACK?

The value if the _rpc dictionary corresponding of your call must be True.
