JTable...how to know if a row is selected?!?

this is my code...i've no compilation problems and the result is quite ok.

the problem is that components in JPanel dx are not shown!!! only when i put mouse-cursor out of the window this components are shown!!

this is what i don't understand!!!!!

CODE:

jtable.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);

ListSelectionModel rowSM = jtable.getSelectionModel();

rowSM.addListSelectionListener(new ListSelectionListener() {

public void valueChanged(ListSelectionEvent e) {

//Ignoro messaggi extra

if (e.getValueIsAdjusting()) return;

ListSelectionModel lsm = (ListSelectionModel)e.getSource();

if (lsm.isSelectionEmpty()) {

int i=1; //non fare niente non c' selezione

} else {

int selectedRow = lsm.getMinSelectionIndex();

dx.removeAll();

JTextField CurrentMac= new JTextField();

Machine current = new Machine(selectedRow+1,c);

ResMsg res = Machine.GetResMsg();

switch(res.GetResult()){

case 5:

CurrentMac.setText("\n I/O ERROR: check your connection!");

dx.add(CurrentMac);

break;

default:

dx.removeAll();

if (res.GetMsg() != null) {

if (res.GetMsg().getType() == GIMsg.GIMACSTSR) {

MacStsRMsg rMsgM = (MacStsRMsg) res.GetMsg();

int cmds = rMsgM.getItems();

CurrentMac.setBorder(null);

CurrentMac.setEditable(false);

CurrentMac.setSelectionColor(new java.awt.Color (250, 250, 220));

CurrentMac.setBackground(new java.awt.Color (250, 250, 220));

CurrentMac.setForeground(new java.awt.Color (0, 0, 255));

CurrentMac.setText("MACHINE ID: " + rMsgM.getMId());

dx.add(CurrentMac);

JCheckBox[] check = new JCheckBox[cmds];

for (int j = 0; j < cmds; j++) {

check[j] = new JCheckBox(rMsgM.getCIdAt(j) + ": " + rMsgM.getCNameAt(j));

dx.add(check[j]);

}

}

else{

CurrentMac.setText("ERROR: Wrong response");

dx.add(CurrentMac);

}

}

else{

CurrentMac.setText("ERROR: Connection error");

dx.add(CurrentMac);

}

break;

}

}

}

});

bye & thank's
