Strange problem in QML calling C++ function..

BBFAG3

@
onClicked: {
urlSelectorr.appendDir(modelData)
t=urlSelectorr.getNowDir()
console.log(t)
}
@

this is my QML code, and the problem is that:
urlSelectorr.appendDir(modelData)
and
urlSelectorr.getNowDir()
can work alone,but if I call appendDir first, getNowDir won't work....
error output is: ReferenceError: urlSelectorr is not defined
it's really confuse me
@
void SPurlSelector::getIntoDir(QString dir)
{
dirList.clear();
QDir seeker(dir);
dirList=seeker.entryList(QDir::Dirs|QDir::NoDotAndDotDot);
ct->setContextProperty("dirList",dirList);
}
void SPurlSelector::appendDir(QString ad)
{
nowDir=nowDir+"/"+ad;

getIntoDir(nowDir);

}

QVariant SPurlSelector::getNowDir()
{
return QVariant(nowDir);
}
@

this is my C++ code. nowDir is a public QString

And if I change the order of calling,which means I call getNowDir() first, following calling "appendDir" is work too.

I found that is
ct->setContextProperty("dirList",dirList);
cause this problem

but I still want to know why...

Sorry for my poor English....
@
int main(int argc, char *argv[])
{
QApplication a(argc, argv);

QQuickView *view=new QQuickView();

QQmlContext *importer=view->rootContext();
SPplayer player;
SPurlSelector urlSelector;

importer->setContextProperty("urlSelectorr",&urlSelector);
importer->setContextProperty("dirList",urlSelector.dirList);
importer->setContextProperty("player",&player);
importer->setContextProperty("playList",&player.playList);

view->setSource(QUrl("qrc:/qml/SPmain.qml"));
QObject *obj=view->rootObject();
QObject *bar = obj->findChild<QObject*>("progressBar");
player.setBar(bar);
urlSelector.setIpt(importer);
view->setResizeMode(QQuickView::SizeRootObjectToView);
view->showFullScreen();
return a.exec&#40;&#41;;

}
@

this is main.cpp

Hi,

What is urlSelectorr ?
