This is the generated code:
private void initComponents() {
jScrollPane1 = new javax.swing.JScrollPane();
scriptTable = new javax.swing.JTable();
setSize(new java.awt.Dimension(200, 200));
scriptTable.setModel(new javax.swing.table.DefaultTableModel(
new Object [][] {
},
new String [] {
"Number", "Name", "Dose", "Instructions", "Date Filled", "Date
to Refill", "Date to Renew", "Date Expires”
}
));
jScrollPane1.setViewportView(scriptTable);
This is my code where I use it:
scriptTable.getModel().setValueAt(num, row, 2); NULL POINTER HERE
scriptTable.getModel().setValueAt(nam, row, 3);
scriptTable.getModel().setValueAt(dose, row, 4);
scriptTable.getModel().setValueAt(instruc, row, 5);
scriptTable.getModel().setValueAt(filled, row, 6);
scriptTable.getModel().setValueAt(tofill, row, 7);
scriptTable.getModel().setValueAt(torenew, row, 8);
scriptTable.getModel().setValueAt(expires, row, 9);
Best Regards,
