I have an entity reference field which is dependent on another entity reference field (using "Business rules - make field dependent using views" widget).
After the node is created, I disable both fields on node edit form for certain user roles. So, when the form is submitted the validation fails with error: This entity (node: 45) cannot be referenced..
This happens because the parent field is no longer present within $_POST (because it is disabled) and the getValidIds method of BusinessRulesViewsSelection returns an empty array.

tavib47 commentedI suggest trying to get the value of the parent field from the entity if the parent field value is empty, but I don't think this is the best idea. I attach the patch which fixes my issue, but it may break something else.

yseki commentedI guess the best approach would be to check if the field was rendered on the form before performing the validation test. I will check it on the next opportunity.

littlepixiez commented#6 worked for me, but the reason my parent entity value is empty is because I'm trying to modify this module to work with Paragraphs. :) Continuing my hacking... thanks for the patch! :D

pcambraI've been testing this on my fork over https://www.drupal.org/project/dependent_fields and I think the code needs to be on validateReferenceableEntities as well as in getReferenceableEntities.
I've pulled the entity from config for getting the parent values in a common way, let's see if this is a correct approach.
