I've added two fields to the canvas of a custom 2nd day operation action. The first field is a text field which is populated by an external action. That works great. The second field I want to be conditionally accessible based upon the contents of the first field. It is a check box. No matter what I do the checkbox is always accessible until I click on the first field. If I click on it then the checkbox field acts as expected either not allowing me access or letting me check it as a confirmation. I'm basically trying to stop even submitting unless certain criteria is met. I could write a second action to set the read only status conditionally but i shouldn't need to. Interestingly the visibility control seems to work just not the read only control. Unfortunately when the visibility is disabled it seems to ignore the constraint I have that the field is required. Maybe two bugs here? Hoping someone else can test and confirm and if so I'll open a support case. Or better yet tell me what I'm doing wrong 🙂
