I have a simple document type (Customer) and content node for it.
Under Customer I have 3 nodes of custom document type Order. When user enters date of the order in Umbraco, I want to check whether exists order with the same order date or not? I assume that I need to execute my custom implementation, but how I can do it to prevent creating orders with the same order date?
Custom validation logic
