Hello Manfred,
I've just tried your product_test module and tested the sames cases as
your video shows and I must say that this is not actually a bug. BTW I
could not reproduce any of the tracebacks you mention in the bug
description, so I assume they are unrelated.
Looking at your videos, you're testing both cases against a 6.1 server,
only the version of the client changes. So if there is any change, it
should be on the client side only, right? But actually what you're
seeing is random, and depends on the version of Python, etc. For example
I can reproduce the same behavior as your video for 6.1 shows, but using
the 6.0.2 client.
Let me explain: when you press "Save" in the form after changing the
price field, the client send an RPC request to the server to save the
changes. This is all done in a single call to the write() method (you
can see it if you enable RPC debug logging), that receives the values as
a map, e.g in the form:
{'packaging': [],
'seller_ids': [[1, 10,
{'company_id': 1,
'delay': 1,
'min_qty': 1.0,
'name': 11,
'price': False,
'pricelist_ids': [[1,
2,
{'min_quantity': 1.0,
'price': 23.0}]],
...
}
The write() method will then process all the values in the map to save
then in the database. But the order in which the fields are saved is not
absolute, because there is no order for keys in a map/dictionary. So the
order in which the fields will be processed depends on many things (like
the python version), and can be considered semi-random.
As you have added a read/write related 'price' field on the supplier info
object, when its value of '0.0' is saved, it will overwrite the price value of
the first price in the lines. You can test that easily by setting a value in
the related "price" field while having multiple pricelist lines: you will see
the first line gets set to the related field value.
If you want to do this, you need to make sure the related field is never
written to. One way to do it is to make it read-only.
If you look at the RPC call for the write() after making the related price
field read-only, you will see that it does not receive a value anymore.
To summarize, the behavior you are showing seems perfectly normal, and I should
now close this bug.
Do not hesitate to provide more feedback or reopen the bug if I misunderstood
the situation.
Thanks,

Invalid
Bug description:
client 6.1 rev. 1928
server 6.1 rev. 3520
Extension of the class product_supplierinfo by 2 Columns:
"prod code" ----- will show the items which the supplier delivers
"price" ----- to show the price of the first article in the
supplierpartner form
With the new column "price" in object product_supplierinfo I can not
save a price. The value remains at 0
class product_supplierinfo(osv.osv):
_name = "product.supplierinfo"
_inherit = "product.supplierinfo"
_columns = {
'prod_code' : fields.related('product_id',
type="many2one", relation="product.template", string='Bezeichnung'),
'price' : fields.related('pricelist_ids', 'price',
type='float', string='Price'),
