How can I create an alias to a property within a Repeater?

This code:

Repeater {
    id: myImageArr
    property alias changeSource: imageElement
    model: 3
    Image {
        id: imageElement
    }
}

gives me an error:

Invalid alias reference. Unable to find id "imageElement"

The Image inside the repeater is dynamically created depending on the model, so you can't refer it directly by id. If your model is a fixed value (3), then you can access the Image instance by using Repeater.itemAt(index) function. For example, to create alias to the first Image created by repeater:

property alias changeSource: myImageArr.itemAt(0)
