Stange question!

[Jason Chen]

hi,everybody,
I have a stange question in my program.
When I have no flight information displayed in the result table and use key TAB in the JTable,
the console prints out the following exceptions:
java.lang.ArrayIndexOutOfBoundsException: 2
at suncertify.client.FlightTableModel.getValueAt(Unknown Source)
at javax.swing.JTable.getValueAt(JTable.java:1760)
at suncertify.client.FBNFrame$FlightSelectListener.valueChanged(Unknown
Source)
....

But if I use mouse on the JTable, this doesn't happen.
Would someone like to help me with this?
If I submit my assignment without correcting this
problem, what is the result of my score(ie, it is important enough)?

Make your cells non editable. I am not sure if your design allows this restriction. You will not get the exception if you don't try to change the value in the cell.

I don't implement the isEditable() in the FlightTableModel whiche extends AbstractTableModel
so I think the cell is not editable.
