[IMP] web: StaticList: support CLEAR (5) orm command Before this commit, the StaticList didn't expose a way to apply a CLEAR command (command 5), i.e. to empty the relation. This commit adds a function to do so, and adds the support of the CLEAR command in . Note: since [1], onchange no longer returns CLEAR commands (it only returns commands from 0 to 4). So this commit adapts a few historical tests that still simulated onchanges returning a CLEAR command as first command.

    [IMP] web: StaticList: support SET (6) orm command

    [IMP] web: StaticList: support SET (6) orm command Before this commit, `_applyCommands` didn't support SET command (command 6). As a consequence, this command had to be special-cased in `_preprocessX2manyChanges`, and in an override of `Record` in the ai_fields addon [1]. With this commit, the SET command is now supported in `_applyCommands`, and a `set()` function has been added on StaticList for convenience. Note: since [2], onchange no longer returns SET commands (it only returns commands from 0 to 4). So this commit adapts a historical test that still simulated an onchange returning a SET command as first command. No task, but followup of [3] [1] https://github.com/odoo-dev/enterprise/blob/366f0376644d4aecd239378782d2db896ea7bf9f/ai_fields/static/src/model/relational_model/record.js#L26 [2] https://github.com/odoo/odoo/pull/119510 [3] https://github.com/odoo/enterprise/pull/830…
