QDeclarativeImageProvider does not load image in container

Hello.

@class QMLImageProvider : public QObject, public QDeclarativeImageProvider
{
Q_OBJECT
private:
QPixmap front;
QPixmap back;

public:
explicit QMLImageProvider();
QPixmap requestPixmap(const QString &id, QSize *size, const QSize &requestedSize);
};@

implementation

@QMLImageProvider::QMLImageProvider() : QObject(0),
QDeclarativeImageProvider(QDeclarativeImageProvider::Pixmap) {}

QPixmap QMLImageProvider::requestPixmap(const QString &id, QSize *size, const QSize &requestedSize) {
return QPixmap(QString("QML/screen1.png"));
}@

registration:

@screenArea = new QDeclarativeView(wgScreenArea);
qmlImageProvider = new QMLImageProvider();
screenArea->engine()->addImageProvider(GlobalVars::imageProviderID, qmlImageProvider);

screenArea->setSource(QUrl::fromLocalFile&#40;"QML/screen.qml"&#41;);
screenArea->setResizeMode(QDeclarativeView::SizeRootObjectToView);@

QML script:

@ Image {
id: backImage
source: "image://imageprovider/frontimage"
}@
works fine, but doesn't work with Column or another container
@Column {

Image {
        id: backImage
        source: "image://imageprovider/frontimage"
    }

}@

whereas
@Column {

Image {
        id: backImage
        source: "screen1.png"
    }

}@
OK.
Why?

P.S. Sorry for my english.

I found answer on stackoverflow: "Columns get a bit funny with items that don't declare their width and height" from funkybro.

@Column {
id:screenImage
Image {
id: backImage
width: screenImage.width
height: screenImage.height
source: "image://imageprovider/backimage"
}
}@
