Please, Ana.

Please do test Olivier's branch and compare with v6.1 before judging.
You will notice that both versions produces the same result: documents
for external communications and forms for internal usage.


The behaviour is exactly the same in v6.1 and Olivier's branch when
sending documents to customers:
  - When printing the document, the sale order/invoice is sent to John
Doe's address (not to ACME's one) [*]
  - When sending by email, it uses John Doe's address, not acme's one.
And this is the correct behaviour!


If John Doe leaves and if you do the mistake to change John Doe's
company and address, the behaviour is exactly the same in v6.1 and in v7
--> wrong result. Whether it's by email or by post, documents are sent
to the new John Doe's address.


As an additional note, can you imagine sending your quote or invoices to
<email address hidden>?
It has no sense to send document to the generic address of a company.
Try to send a quote to <email address hidden> :) You have to send quotes to
<email address hidden> otherwise your email/letter will be lost in the company.

If someone leave the company, most companies redirect their emails and
letters to the responsible that replaces him, so this is not a problem.


If you change the company a person is working for (instead of creating a
new contact in the new company), you will create:
  - inconsistencies in v6.1, you get on printed addresses:
      Old Company
      Person
      New Company Address
  - in v7, you do not get an inconsistency as the model ensure it's
always correct (but it's may be not what the user expected):
      New Company
      Person
      New Company Address
The v7 behaviour is consitent (suppose you merge two identical partners
created by mistake) but I agree that it's not what the user may expect.

--> in this case the real solution is to add a Warning: "Are you sure,
this will...". Certainly not to reproduce the inconsistency of v6.1.
So, this is a very bad scenario. And the bug to fix is to ensure the
user do this only if he really intended to do this. It has nothing to do
with the quality of the solution/data model.


[*] You may have not noticed it as v6.1 does not print the name on the
invoice, which is a bug that has been fixed in v7. But it really uses
John Doe's postal or email address, not Acme's one.


> I feel really silly trying to explain this to someone. I can not realize
> how anybody can not see this approach...

Thanks for taking the time to provide your input. But, can you please
provide a real business case based on real tests you did on the branch
to avoid more confusions?
