In case of error, the send & print wizard is crashing or log an error on the invoice chatter.
In that case, nothing is sent to the end-customer.
This is problematic for all flows in which we want to send a mail to the customer automatically.
For example, e-commerce with automatic invoicing or subscription/recurring invoices.
To avoid that, the current logic of the send & print has been reshaped. In case of error, a proforma
PDF is sent instead. This is exactly the same document as the PDF but without the legal layer.
To do that, a lot of refactoring has been necessary to always provide the cumulated data for invoices
to be able to access the generated proforma report and to allow the overrides to know exactly in which
mode the hooks are called.
Also, this commit renames the method by something less generic about invoices. Indeed, this wizard needs to be
usable for others documents than invoices. That's the purpose of the invoice_single/invoice_multi mode.
For that reason, all methods about invoices are now expricitely prefixed by 'invoice'.
Fix also a performance issue on multi-invoices since the invoice_pdf_report_id document was invalided for the
whole model instead of the current record. When dealing with X invoices, the whole model was invalidated X times.
Fix the managment of attachments:
- The manual attachments wasn't send when sending a mail 'invoice_single' mode.
- When changing to another mail template, the manual attachments were lost.
Fix the double generation of PDF using a web-service.
When opening again the send & print wizard, the PDF must not be regenerated but reloaded from the previous one.
