The problem is at this code:
public void selectionChanged(int arg0, int arg1) {
...
tableTeam = new Table(model);
if (count == 1) {
teamsContainer.addComponent(tableTeam);
count = 0;
}
count = count + 1;
...
}
This code snippet means that you add another Table each time you select another value from the ComboBox : DON'T RESET "count" TO 0 !
