Hello,
I don't know if i found a bug or made a subtle mistake:
I wrote a small module to have list prices and cost prices stored in the
product not just in the template.
If i install or update the module with trytond-admin it works fine, but
when i update any module with the client, it gets broken and the prices
are greyed out in the product(variant) form again. when i update my
module with trytond-admin again it works again.
i use trytond 4.2 with postgresql
the command that gets it running is:
trytond-admin -c ./trytond.conf -d tryton2 -u product_variant_price
i did a DB-dump in the broken state and after running trytond-admin. The
difference are just different timestamps in the tables ir_cache, ir_lang
and ir_model_data and the changed lines in ir_cache and ir_model_data
are listed in another position.
Can this be the reason for a module working or not?
Best Regards,
Ulrich
