Steps to reproduce:

1. Create parameter parent1
2. Create parameters child1 and child2, with a "type": "list" and "values": { "script": "some_script.sh ${parent1}" }
3. This some_script.sh should provide the same results for any value (or just empty)
4. On UI, put any value to parent1
5. Then replace this value with any other value

Result: child2 parameter is disabled and showing rotation spinner
