I have a task form with a few lookup fields. I have a rule set up that dictates whether the fields are read only or not. This works fine - the fields are disabled/enabled appropriately when I tell it. However, when the rule enables the field, no values show up in the dropdown.
If I remove the rules entirely and let the field be enabled all the time, the values show up again in the dropdown. Why is it when I apply read-only rules do my lookup dropdown values not appear?
