Issue Summary

The isEmpty() function doesn't work for cascading list fields with empty values. It only works when the fields have a value. The same for the function isNotEmpty().

Steps to Reproduce

1. Create a cascading list custom field
2. Add the field to an issue and keep the value empty
3. Use the function {{issue.Custom Field Name.isEmpty()}} or {{issue.Custom Field Name.isNotEmpty()}}

Expected Results

The function should return TRUE/FALSE

Actual Results

The function returns nothing

Workaround

Use a smart value condition on the rule
