I've used a "ticket custom field" (a single choise type: "not yet; done") to trigger an action rule
This field is an "Additional Activated Custom Field" for only one state, not visible by any Request Type.
After using this custom field to enable the rule of action and change state to the ticket the field remains visible.
I want to see this field ONLY if the thicket has a state and not another!
How do I reset this field and bring it back to null?
Thanks
Adriano
