Focus should remain at the command link

Question

I have Command links and I want to do everythibg(moving from one link to other and want to perform operation) using "tab" key instead of selecting it through mouse.
when ever user selects the command link,one popup will be displayed
,under the popup,a dialog window of type "ok Cancel" was taken,in the dialog window one input text was taken.
The Problem is without entering the text in the input text and clicking on ok button using tab,remains the focus of the cursor on the command link and
also while clicking on the cancel button the cursor position remains at the command link only but
when ever user enters the text in the input text and
selects the ok button using tab,the cursor focus is moving to top of the page,not remains at the command link.This problem is not taking place while
using mouse.
Can anyone please tell me how to the remain the focus at the command link.
I am using jdev 11.1.2.3

Okay, that makes sense. However, I modified my code to actually move the lead, and it still didn't work. Curious, I added a pop up window to the code, and I found out that it doesn't get called. The tab key still doesn't do anything. I miss KeyListeners already :(
Can you spot anything wrong with how I'm doing this?
InputMap im = _table.getInputMap(JComponent.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT);
KeyStroke tabKey = KeyStroke.getKeyStroke(KeyEvent.VK_TAB, 0);
Action tabAction = new AbstractAction(){
               public void actionPerformed(ActionEvent e){
                    int leadColumn = _table.getColumnModel().getSelectionModel().getLeadSelectionIndex();
                    leadColumn ++;
                    if(leadColumn > 4){
                         leadColumn = 4;;
                    _table.getColumnModel().getSelectionModel().setLeadSelectionIndex(leadColumn);
                    JOptionPane.showMessageDialog(null, "L: " + leadColumn);  //this doesn't happen either
im.put(tabKey, tabAction);
