Hi everybody,

i have a really frustrating problem with Jtable. I created a class to display the jtable and a class that extends AbstactTableModel to use as its model. I can update my table after a fireTableDataChanged method in the class that extend the AbstractTableModel, but after implementing a ListSelectionListener to the class that displays the jtable, it gives a big bunch of errors in the console of my ide, when i remove it, it went back to normal without any errors.

Anyways, my program still can run without problem and the table still can refresh, just this bunch of errors when i clicked the button that calls the AbstactTableModel to perform a firetabledatachanged

anybody got this problem? how did you guys solve it?
