"name": "Compute client-side domains on x2many fields correctly",
"version": "1.0",
"author": "Therp BV",
"license": "AGPL-3",
"complexity": "normal",
"description": """
When using ``attrs="..."``, evaluation of x2many fields nearly always goes
wrong in ways not to be expected when being used to server side domains in
Model.search().
This addon fixes those cases while keeping backwards compatibility for cases
where you might have checks in a somewhat hacky way, ie. ``attrs="{'invisible':
[('category_id', '=', [[6, False, []]])]}"``.
