If I use the below code I don't get the error, but I get "false" strings in the column.
public Class getColumnClass(int column) {
Class returnValue;
if (column == 1) returnValue = String.class;
else if ((column >= 1) && (column < getColumnCount())) {
returnValue = getValueAt(0, column).getClass();
} else {
returnValue = Object.class;
}
return returnValue;
}
