celleditor won't stick

[Ben Zung]

I have table

 
public MyTable(DefaultTableModel model){
super(model);
setDefaultRenderer(model.getColumnClass(0),
new MyCellRenderer()); 
setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
setRowHeight(getRowHeight()+5);
setRowMargin(getRowMargin()+5);
setSelectionBackground(java.awt.Color.yellow);
JTableHeader header = getTableHeader();
header.setDefaultRenderer(new MyHeaderRenderer());
JTextField editor = new JTextField(10);
DefaultCellEditor cellEditor = new DefaultCellEditor(editor);
setCellEditor(cellEditor);
}
 

And later I make a call

 
DefaultCellEditor cellEditor = (DefaultCellEditor)myTable.getCellEditor();
if (cellEditor != null)
      cellEditor.stopCellEditing();
       

Odd thing is, that the cellEditor is null. what am I missing?
thanks in advance.

i think it is a scope issue. you only show the constructor for MyTable, but i notice you use a local variable
DefaultCellEditor cellEditor = new DefaultCellEditor(editor);
make that an instance variable and i think will fix problem

[Ben Zung]

That's not true, I think.
The cellEditor is being set during the table construction. So it should stick with the table. It then exists in the table interval structure until
the table get GCed. And I can be sure that that's the only constructor and the table has not been reconstructed in other way.
And please notice that I call myTable.getCellEditor() which as far as I
understand it, should return the one we set for early on.
Any more thoughts?
Thanks for the response.

d'oh! i see now
DefaultCellEditor cellEditor = (DefaultCellEditor)myTable.getCellEditor();
did you make an instance variable in main() called myTable? is it an instance of MyTable class? did you write method getCellEditor()?

[Ben Zung]

I do have a instance of MyTable called myTable in the main.
And the MyTable constructor part you've seen in my first post.
There is another method in MyTable I named it

      public void stopMyTableCellEditing(){
         DefaultCellEditor cellEditor = (DefaultCellEditor)getCellEditor();
         if (cellEditor != null)      
            cellEditor.stopCellEditing();
         else
            System.out.println("cell editor is null");
      }

In my main method, I call myTable.stopMyTableCellEditing() trying to flush
the changes made to the tableModel data vector.
getCellEditor() and setCellEditor() is are JTable methods. I don't write them myselft.
Hope this clear things better
Thanks for the message

Please pardon my English too.

In my main method, I call myTable.stopMyTableCellEditing() trying to flush
the changes made to the tableModel data vector.

I meant to flush the changes made to the table view into the table model data vector
