As long as the framework is not able to avoid rewriting values that are already set, we must add checks to avoid triggering multiple processes linked to that value assignment. Example: https://github.com/odoo/odoo/blob/66c11acdbedf8d1bcae6deb8ec54c5da5a3ae16d/addons/stock/models/product_strategy.py#L111 https://github.com/odoo/odoo/blob/11d81b2145e95c50481101a63d3ad1d244279af4/addons/stock/models/stock_move.py#L302-L341 https://github.com/odoo/odoo/blob/daea3d4e10b8fc2c4840fff30474a1203eff55c2/addons/sale_stock/models/sale_order.py#L402-L418 It may be unusual for a field to compute stored depending on a non-stored, but the reality is this. closes odoo/odoo#152026 X-original-commit: 123212a5f5598d91f31869c49ac8d28aba1f698a Signed-off-by: William Henrotin (whe) <whe@odoo.com>
