Problem/Motivation

The action "Form field: set options" allows to set custom options on any options field, including entity fields.

When the custom options don't include an empty value on their own, but the default value is not specified (i.e. to be empty), then this may lead to an illegal choice error on form submission. Also when resetting one of the first fields to a different value, the form is not capable of resetting the other choices.

Attaching a sample model that has some complex dependencies between fields, that can be changed via Ajax. When selecting a value in "First" field, then an illegal choice error will show up on the "Second" field.

Steps to reproduce

Proposed resolution

When the default value is not specified other than to be empty, then it should be automatically made sure, that the empty option never gets lost.

When the creator of an ECA model does not want an empty option to be available, a default value other than the empty one can still be specified with "Form field: set default value, then the empty value is not needed.
