[Qt-qml] Repeater child count

Hi all,
I don't understand this behaviour:
I have a QAbstractListModel subclass implemented in C++ and exported to
the QML code.
The problem comes when I modify the contents of the model. Here is the
QML code I'm testing with:
Item {
id: seatView
anchors.fill: parent
onChildrenChanged: console.log("Children length " +
seatView.children.length);
Repeater {
objectName: "repeater"
model: handModel
Text { text: name }
}
}
When I do a dataChanged(index(0), index(rowCount() - 1) or a reset() in
the model, the number of children of the view grows. It actually grows
with exactly rowCount() new children, but the old are still there. I
have checked that rowCount() stays the same :)
Did I do something wrong here, or is this a bug? It certainly can't be
right that the number of children in the view grows on data changes.
Then I would have to stop using the model and just go with a hardcoded view.
My model is a simple list model subclass with only rowCount and data
implemented. There is nothing odd in the code, AFAICS.
