Set non displayed property to null

[mpiot]

When the dependent field is not displayed, but is previously set, it should be nice to set it to null or a default value we want.
I don't really know if this can be implemented rirectly, or maybe, mentioned in the documentation to remind people implement it.

Eg:

public function setMeal(Meal $meal): static {
    $this->meal = $meal;

    if ('breakfast' !== $meal) {
        $this->rating = null;
    }

   return $this;
}

Yes... I haven't really thought about this. I guess, inside the form, if 'breakfast' !== $meal, the rating field will be removed... so the result would be that setRating() is never called... and so it would keep whatever value it had when the object was first passed to ->createForm() (i.e. the value set in the database).

Can you confirm that my statement above is accurate? If so, yes, my feeling is that this would be a good fit for the docs.

Yes, because we remove a field, then we never call the setter and the object keep the initial value.

I don't really know which is the best way to change that value:

• setter
• change the data when removing or not adding the field
• add a final POST_SUBMIT event that check for example: if 'breakfast' !=== getMeal() then setRating(null)
