controller

问题 There are two different stages in my application that are help screens that use the same FXML file.

问题 I have two controller file homecontroller and backendcontroller. What is the best way to create global function and access it from both files?

This can happen if the route that services this request ('{controller}/{action}/{id}') does not specify namespaces to search for a controller that matches the request.
