JTable doesn't update no matter what I try!!

Question

I populate a JTable from a file at runtime, then I manually read the file again to chech for updates, that work's fine, but to display the new content I have to click on the next empty row to update the screen.. I have tried updateUI, fireTableDataChanged and I don't know how many others, I'm using a TableModel.. The table is in a splitpane, should I call repaint on the splitpane instead? Well that doesn't work either anyway..
Thank's very much for your help!!!!

Answer 1

I wrestled with that for about 20 hours before getting it.
Here's some of my code:    makeButton("Refresh Table",northP,
    new ActionListener()
      public void actionPerformed (ActionEvent e)
        updateTable();
  public void updateTable()
    ch.sendShowAll();
    model.handleServerMessages();
    model.fireTableDataChanged();
/////////////////////This worked for me.
Both these methods occur in the JFrame class that displays the table. I pass the table
model to the JFrame constructor. In the above code, the model object is an instantiation
of the class that extends AbstractTableModel, with the methods getElementAt(), getRowCount(), and getColumnCount().
If you post some of your code,I'll try to help.
