That is not what I meant. The user is changing the field, I want by action to check if such field has been changed on the form, so I can trigger another action.
Let me write how I understand it:
1. A field is changed
2. Something running in the background watches a bunch of fields.
3. If a field in this list of field is changed, 2 will run an action
Why can't the field itself run such an action? If it's always the same action, you could create a form rule in the process and reuse this form rule in each field, which you would check.
Clicking on the usage tab of the form rule would also show which fields use this action.
If you need to pass the value from the field to the action, you could also add a parameter to the form rule.
