ScrollPane Help

Question

initially i didn't split the panel and data..
the scrollPane was showing good (table - JTable)...
            table = mainPanel.atmBean.getReturnTable();
            //Set Mode, Border, Size
            table.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
            table.setBorder(BorderFactory.createEtchedBorder());
            table.setPreferredScrollableViewportSize(mainPanel.getPopupTablePreferredSize());
            //Add table to Scroll Pane
            scrollPane = new JScrollPane(table);
            scrollPane.setPreferredSize(mainPanel.getPopupTablePreferredSize());after splitting the data, i changed like
add()
scrollPane = new JScrollPane();
set()
            table = mainPanel.atmBean.getReturnTable();
            //Set Mode, Border, Size
            table.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
            table.setBorder(BorderFactory.createEtchedBorder());
            table.setPreferredScrollableViewportSize(mainPanel.getPopupTablePreferredSize());
            //Add table to Scroll Pane
           //THIS IS THE DIFFERENCE
            scrollPane.add(table);
            scrollPane.validate();
            scrollPane.repaint();
           //c is contentPane()
           c.validate();
           c.repaint();
}the scrollpane doesn't seem to contain the table..

Answer 1

if i add 1 more panel, the problem gets solved, but wondering why shouldn't the scrollPane work ..
ie
add()
  JPanel panel = new JPanel();
set()
  ..all other steps as shown above
  scrollPane = new JScrollPane(table)
  //one more panel
  panel.removeAll();
  panel.add(scrollPane);
  panel.validate();
  panel.repaint();
}
