    Default Help with JList

    Hi, Could someone help, I have a TextArea that a user enter text then submits the text to the database, i have a JList that retrieves the text and displays it. the problem is the list does not update immediately i have tried repainting the list but it seems not to work.
    the JList code on post-creation

    Java Code:
    //code
    listModelMsg = new DefaultListModel();
    
    String msgList = "SELECT msg_text FROM msg_board ORDER BY msg_id ASC";
    
    try
    {
    this.resultSet = this.connection.executeQuery(msgList);
    
    while(this.resultSet.next())
    {
    listModelMsg.addElement(this.resultSet.getString("msg_text"));
    
    }
    jList12.repaint();
    jList12.setModel(listModelMsg);
    }
    
    catch(SQLException e)
    {
    e.printStackTrace(System.err);
    }
    Thanks

    I'll be honest that I find that when I was doing heavy GUI work in my undergrad I came up with this problem frequently.

    And to be honest I can't remember how I fixed it, however I did find a helpful link on how repaint works:

    My only suggestion is to try and add validate() before the repaint.
    Or put an int parameter in there. Besides that I'm unsure and if there is a more stable solution I'd like to hear it as well.
