If you get an error when clicking the Login button, make sure that your Scene2.fxml document has Scene2Controller as its controller.

What about if I want to update a method in differnt controller from another controller

[socaljusticewarrior]

I hate JavaFX. I would much rather work with Swing. It's baffling that I have to create a class, create an XML file(excuse me, an "FXML" file) for the class to load, then specify in the FXML file that I want to have these methods and objects. It's super redundant, but it's easier to update and modify than the Swing GUIs, so I guess employers like it for that reason.
