Hello,

   I am extending "AbstractTableModel" using Java 1.3.  I can double click on a cell and enter data into the JTable, but all of the entered data disappears when I double click a different cell ("change editing focus").  "setValueAt" is not executed, but "isCellEditable" is executed.  A snippet of the "AbstractTableModel" is listed below:



public boolean isCellEditable(int row, int col){ return true; }

public void setValueAt(Object aValue,int rowIndex, int colIndex) {
       data[rowIndex][colIndex] = (aValue==null?aValue:aValue.toString());;
       fireTableCellUpdated(rowIndex, colIndex);
}

How do you know setValueAt() is not getting called.

Can you post your getValueAt() method.

Have you implemented your own CellEditor?
If so, make sure that you are calling cancelCellEditing() and stopCellEditing().

>>I am extending "AbstractTableModel" using Java 1.3

You may well find that extending DefaultTableModel is much easier as the basic functionality is already implemented for you.

Found my problem,  I was overloading "editingStopped" when I extended JTable.  Thank you all for you inputs.
