Error : Detected background switch for net_rim_bb_ribbon_app(58) who has NO tunnels open - defocus NOT called

Question

Hi There

Im working in eclipse with bb plugin and the problem is when i click in my app then simulator freezes and I can not do anything. I tried to do something but its still the same

And Also I app have a background component (THREAD), here i leave the code when i call the method

app have a background component

public void callback(final ServiceResult result) {

    if(result.getException()!=null){
        UiApplication.getUiApplication().invokeLater(new Runnable(){
            public void run() {
                Dialog.alert("error:"+ result.getException().getMessage());
            }
        });
        return;
    }
    this.section = (Vector) result.getData() ;
    // take first element of Result Object
    final Section section = (Section) this.section.elementAt(0);

    UiApplication.getUiApplication().invokeLater(new Runnable(){
        public void run() {
            pushScreen(new SubsectionScreen(section, 0));
        }
    });


}
