How to lock commandlistener for certain time (to ignore buttons whie next )

Question

Hello,
I have a following (perhaps trivial) problem: I have a couple of methods which creates next screens in my app (meth1()...meth2()..meth3()). I have an "next" button, which swiches me between screens. Between switching to next screen I'm doing some gprs connection (in commandAction(Command c,Displayable c )) whitch take some time. Now, when user pushes my "ok" button couple of times, the commandlisteners works for all of them and when the gprs conn ends it puts mi two screens away. How can I lock input until next 'screen'(method) is invoked?Here's my sample code:
                public void myScreen1(){
             currentMenu="myscr1";
                              Form f=new Form("Screen1 ");
             DateField godzPoczatkowa=...
                                          f.append(godzPoczatkowa);
             f.addCommand(backCommand);
             f.addCommand(okCommand);
                               f.setCommandListener(this);
                                     myDisplay.setCurrent(f);
                public void myScreen2(){
             currentMenu="myscr2";
                              Form f=new Form("Screen2 ");
             StringItem str=...
                                          f.append(str);
             f.addCommand(backCommand);
             f.addCommand(okCommand);
                                f.setCommandListener(this);
                               myDisplay.setCurrent(f);
             public void myScreen3(){...}
public void commandAction(Command c, Displayable d) {
      String label = c.getLabel();
      if(label.equals("Ok")&?tMenu.equals("myscr1")){
            //gprs connection which locks app for couple of secconds
                   myScreen2();
      }else if(label.equals("Ok")&?tMenu.equals("myscr2")){
                   myScreen3();
           }else if(....myscr3)Hope U can help,It's pretty urgent for me.Thanks in advance

Hi,
Use a boolean variable as a flag which will be true when the connection is taking place. and in the commandAction method if the flag is true just say return. else the event will be processed.
