QT QDeclarativeImageProvider child class single instance?

[tkastlunger]

Hi,
has someone else seen this?
I have a

class QMyImgProvClass : public QDeclarativeImageProvider{
..
virtual QImage requestImage(const QString &id, QSize *size, const QSize& requestedSize){
...
}
QMyImgProvClass * instance(){
static QMyImgProvClass s_myClass;
return &s_myClass;
}
public:
QList<int> m_list;
};

Since I need to use this in a plugin, I register it in the

void BookmarkModelPluginPlugin::initializeEngine(QDeclarativeEngine *engine, const char *uri){
engine->addImageProvider(QLatin1String(MY_IMGPROV_NAME), QMyImgProvClass::Instance());
}

through a simple Singleton.

In the plugin then, I populate the m_list;
.
Now, the requestImage is called correctly from QML. BUT, the effect is that the m_list list is EMPTY for each call. It seems that for each call to the requestImage, the "this" pointer is different.

I thought the addImageProvider registers a single object as an image provider?
