These warnings will become errors in the future - Santiago Palacios/Epicor
If I understand Santiago, Epicor will provide safer ways to get the same functionality. Keep track of the places you do this in your source control system. (Sorry, it’s Friday - I don’t know what I was saying.) I think it’s the same code on-prem or in the cloud, so be prepared - just in case.
