I've spent hours pouring over forums and the internet in general for a solution to this problem. I set the id in layout but didn't use the fx:id dropdown in code. Now it works and I feel motivated again! Thank you!

Well I have the fx:id right and i'm still getting NullPointer when I try to setText() on a TextField. Do you have to do something on the initialize() method?

Wholy shit fx is bad. Okay so there are two fields fxid and id, make sure your using the fxid or it doesn't work.
