In a client script, when triggering a setValue action on a field that is set up with a SOURCE LIST and SOURCE FILTER BY relating to another field, how do I get both the fields to update? The “parent” field will update but the other does not (I have tried with and without ignoreFieldChange). Do I need to introduce a delay on setting the second field or something?

Have you tried adding

fireSlavingSync: true

weird, it’s not in the documentation for record.setValue
