Всем привет!

class IDownloaderObserver
{
public:
    virtual void OnCompleted(CString const& fileName)    =0;
};

typedef shared_ptr<IDownloaderObserver> IDownloaderObserverPtr;

typedef vector<IDownloaderObserverPtr> DownloadObservers;

class DownloadSubject
{
public:
    void registerObserver(IDownloaderObserverPtr observer);
    void removeObserver(IDownloaderObserverPtr observer);

protected:
    void notifyCompleted(CString const& fileName);

private:
    /*DownloadObservers*/ vector<IDownloaderObserver*> downloadObservers;
};

void DownloadSubject::notifyCompleted(CString const& fileName)
{
    for_each(    downloadObservers.begin(),
            downloadObservers.end(),
            lambda::bind(&IDownloaderObserver::OnCompleted, lambda::_1, fileName)    );

}

Выше приведенный код прекрастно компилируется...
Но давайте изменим тип downloadObservers на DownloadObservers ...
Как теперь заставить его работать? Пишет ошибку:
