Hello.

If I filter on a one2many field to exclude one value, is the filter apply if the excluded value is not the only value of the field?

Some context:

I got a model A with a one2many field linked to the model B.

On the TreeView of the model A, I want to apply a filter to exclude each instances of model A with a link to a specific instance of model B. The domain of the filter I tried is: [('myfield.year','!=','2018')]. As `myfield` is a one2many, an instance of model A can be linked to many years.

The problem:

It work when model A had only one link to an instance of the model B, the one I want to exclude. But if an instance of model A got many link to instances of model B, with one is the one I want to exclude, the instance of model 1 still shown on the view.

Example: If one instance of model A is only linked to 2018, it is filtered. But if it is linked to 2017 and 2018, the instance of model A is not filtered

Thx for your help
