Set Table row data in to a form by action listener

[chamini prashakthi]

Hi ranchers....
I'm doing a swing application.
I have a  Table and input form.What I want to do is when I click a row in the table The input form must fill with the data that table row has.
I created my own table model by extending Default table model.
this is a part of that TableModel.java

import java.util.ArrayList;
import java.util.List;
import javax.swing.table.DefaultTableModel;
public class TableModel extends DefaultTableModel
{
private ArrayList<Data> medicalRecords=new ArrayList<Data>();
 public TrainingMedicalNoteData getSelectedData(int row){
   return medicalRecords.get(row);
 }
}

this is how I call my action listener by click a row

medicalRecordTable.getSelectionModel().addListSelectionListener(new ListSelectionListener()
   {
     
     @Override
     public void valueChanged(ListSelectionEvent e)
     {
       int selectedRow = myTable.getSelectedRow();
       if(selectedRow>0){
         Data nodeData = myTableModel.getSelectedData(selectedRow);
         insertPanelObject.setDataToInsertPanel(nodeData);
       }
       
     }
   })

;

this is the setDataToInsertPanel method in Input form

public void setDataToInsertPanel(Data selectedMedicalNote)
 {
   clearInputPanel();
   setNoteTypeCombo(selectedMedicalNote.noteType);
   setCareProviderCombo(selectedMedicalNote.careProvider);
   setUnitCombo(selectedMedicalNote.unit);
   setDateTime(selectedMedicalNote.noteDate);
   setNoteTextArea(selectedMedicalNote.description);
  }

 
  When I debug my prgram I found that my Arrry index bound exception is occur inside the getSelectedData(selectedRow) method.
please some one help me to get out from this problem.

I created my own table model by extending Default table model.

The DefaultTableModel already provides data storage and methods to access the data. You typically only extend DefaultTableModel to override methods like getColumnClass(...), isCellEditable(...) to change the default behaviour of the model.

If you want to store a custom object then you should be extending AbstractTableModel and you then need to implement all the methods of the TableModel interface to access the data in your custom model.

Check out the Row Table Model for a step by step example on how to create a custom model.
