NullPtrException when reading JTextField
posted 5 years ago
do you really expect someone to go through your almost 600 lines of code? And as Dave said, you never create recipeNameField. The ONLY place I see it is on line 112 of your TbEvent class in the "public TbEvent(JButton t1, JTextField tf1, JComboBox tf2, JSlider tf3, JSpinner tf4, JSpinner tf5)" constructor...but it's never declared anywhere.
