Intercepting editing start and stop/cancel in a JTable

Question

Hi,
I've been seaching the forum for days but could not find anything that solved my problem.
Problem:
I'm writing a multiclient server. The data of the server is displayed in a JTable. The rows(cells) in the table is editable and to make sure no two clients edit the same row at the same time I've implemented a locking mechanism in the server and would like to lock a row whenever a user starts editing and release the lock when the user either stops or cancels editing.
The JTable is 'hooked up' with a TableModel class that I've written to handle the locking and notification of the lock and unlock events from the server.
I've tried a couple of things but non worked very good. It would be nice if the CellEditorListener implemented a startEditing but it does not so letting my model implement the interface was no good.
Any ideas? If anyone knows how to solve this, please reply
Yours, Johan

Playing around with some methods in JTable, and some minimal testing, I came up with:
table = new JTable(...)
     private int editingRow = -1;
     public  boolean editCellAt(int row, int column, EventObject e)
          boolean editingCell = super.editCellAt(row, column, e);
          if (isEditing())
               editingRow = row;
               System.out.println("started");
          return editingCell;
     public void removeEditor()
          if (isEditing())
               editingRow = -1;
               System.out.println("stopped");
          super.removeEditor();
};
