have various classes representing various types of program-genres (comedy, drama etc).
I have a text file filled with '-' seperated values that get read by a class called Processing and puts them into a LinkedList.
I have another class GUI_g that creates the GUI. It has 3 JTables. One for the list and 1 for each Channel. (Channel 1 and Channel 2). The JTable listTable gets filled from the linkedlist and whenever a user clicks on a row, the textfields' text changes accordingly.
I tried with 3 fields (Title, Genre and Duration) and it worked, with the 3 textfields showing different text according to what row is clicked. However when I added all the needed values, an error comes up and no fields are filled.
I have two problems:
- If it's a MusicVideo the cells are not filled up (as it should be) however it returns an error when copying data to the JTextFields
- The Snyopsis column remains empty and is not filled.
Below are the classes (the ones mainly used). If you need others tell me and I'll upload.

This is the error I get:
Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException
JTable mouseListener:
listTable.addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent e) {
if (e.getClickCount() == 1) {
JTable target = (JTable)e.getSource();
int row = target.getSelectedRow();
int column = target.getSelectedColumn();
String title = listTable.getValueAt(row, column).toString();
String duration = listTable.getValueAt(row, column+1).toString();
String genre = listTable.getValueAt(row, column+2).toString();
String actor = listTable.getValueAt(row, column+3).toString();
String director = listTable.getValueAt(row, column+4).toString();
//String rentable = listTable.getValueAt(row, column+5).toString();
//String synopsis = listTable.getValueAt(row, column+6).toString();
txtTitle.setText(title);
txtDuration.setText(duration);
txtGenre.setText(genre);
if (listTable.getValueAt(row, column+3) == null) {
listTable.setValueAt("N/A", row, column+3);
txtActor.setText("N/A");
}
else {
txtActor.setText(actor);
}
if (listTable.getValueAt(row, column+4) == null) {
listTable.setValueAt("N/A", row, column+4);
txtDirector.setText("N/A");
} else {
txtDirector.setText(director);
}
