So basically I made a UI with text fields and buttons. I want to have focus on the submit button when the window first starts up, but i get a null pointer exception right on that method.
submitBTN.requestFocus();
Is there something I'm missing?

1Have you shadowed the variable, initialise the local variable and not the instance variable? – MadProgrammer Jul 31 '15 at 07:20
