EditCellAt() with mouseclick is not working for first row of the jtable

Question

Hi All,
I have extended JTable.changeSelection() & editCellAt() methods to force the text to select when focus is brought to the cell.
I have a page which has both editable and non-editable columns. when I do a mouse click on FIRST ROW of the editable cell and type the value, The value is not displayed in the cell. when I click on any other editable field in the page, The typed value is displayed in the cell. In the first row of the cell, only the first attempt is not working. When I remove the editCellAt() call in changeSelection(), it works as expected.
But, If I reach the FIRST ROW editable cell using TAB key instead of Mouse click and type the value, its working fine.
Kindly suggest me what could be the problem in my code. I think something wrong in editcellat() or mouseclicked/released or focusgained in our versions of JTable or jtextfield.
Kindly let me know if you need any more functions of my version of implementation.
Thanks In advance.
My JTable Version of editCellAt:
     public boolean editCellAt(int row, int column, EventObject e) {
          try {
               if (getCellEditor() != null && !getCellEditor().stopCellEditing()) {
                    return false;
               if (!isCellEditable(row, column)) {
                    return false;
               if (isShowStarRow() /*&& !starRowAdded*/) {
                    VSDataControl ds = getDataSource();
                    if (ds != null) {
                         VSResultSet rs = ds.getResultSet();
                         if (rs != null) {
                              if (row == rs.getRowCount()) { // This is the star row
                                   // Go to the last record
                                   if (row > 0) {
                                        try {
                                             rs.getRowAt(row + 1, true);
                                             rs.last();
                                        } catch (Exception ex) {
                                             return false;
                                   if (ds.insert() == null) {
                                        return false;
                                   currentRow = row + 1;
                                   starRowAdded = true;
               TableCellEditor editor = getCellEditor(row, column);
               if (editor != null && editor.isCellEditable(e)) {
                    editorComp = prepareEditor(editor, row, column);
                    if ( editorComp instanceof VSGridChoice && lastKeyEvent != null ) {
                         VSGridChoice choice = (VSGridChoice) editorComp;
                         choice.handleMissingCharEvent( lastKeyEvent );
                    if (editorComp instanceof VSChoiceBase && lastKeyEvent != null ) {
                         VSChoiceBase hack = (VSChoiceBase)editorComp;
                         hack.addMissingChar(lastKeyEvent);
                    lastKeyEvent = null;
                    if (editorComp == null) {
                         removeEditor();
                         return false;
                    editorComp.setBounds(getCellRect(row, column, false));
                    add(editorComp);
                    editorComp.validate();
                    editorComp.requestFocus();
                    setCellEditor(editor);
                    setEditingRow(row);
                    setEditingColumn(column);
                    editor.addCellEditorListener(this);
                    return true;
               return false;
          } catch (Exception ex) {
               showValidationError(e, ex);
               return false;
     public void changeSelection(int rowIndex, int columnIndex, boolean toggle, boolean extend)
          super.changeSelection(rowIndex, columnIndex, toggle, extend);
                editCellAt(rowIndex, columnIndex);
                       if (getEditorComponent() != null)
               if (getEditorComponent() instanceof CustomJTextField)
                    ((CustomJTextField)getEditorComponent()).selectAll();
      }

Answer 1

i will suggest you to override your requetFocus()
like.
public void requestFocus()
        super.requestFocus(); // may be panel or container.
        textPane.setSelectionStart(0); // textpane is the editor for the cell.
        textPane.setSelectionEnd(textPane.getText().length());
    } Gud luck.
