How to make a field read-only based on another field in Requisitions

Summary

Making a field read-only based on value of another field (using partialTriggers)

Content

Recently there was an inquiry on how to make the 'Negotiation required' flag read only when user checked the 'Negotiated' flag and vice versa. This article provides guidance on how to achieve this.

One of the standard ways of implementing this is to personalize the Add Requisition Line page and use the partialTriggers component properties and expression language. By using the partialTriggers component property you can control one component (referred to as the target component) based on event occurring on other component (referred to as the trigger component) by setting the unique ID of the trigger component in the partialTriggers attribute of the target component.
