Possibly remove ListSelectionListener before clearing Jtable (runtime)?

Question

I have written a ListSelectionEvent for my jTable.

It works to take values from specific cells and put the value into the cells corresponding jTextField.

So, I upload a CSV file to the jTable. It loads.

I click the button at the bottom labeled "Clear Table". The table is cleared and a new blank row is made (I couldn't get around doing this. Otherwise it wouldn't let me load another CSV file)

My problem :: I load another CSV File. It loads. I select a row, the listSelectionEvent fires, and executes as it should. I click "Clear Table" and it throws this Exception.

Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: -1

After this the program starts bugging out and needs to be closed. The jTable does clear when the window is resized.

Thanks in advance for help with this.

Before you do any calls to the model using table.getSelectedRow(), you should first check if this value is >= 0.
