Running with Qml debugger (assuming this uses the bytecode representation):

Running in normal mode (no debuggger attached):
QML debugging is enabled. Only use this in a safe environment. qml: BAR QQuickItem(0x6000000f48c0, "Bar") qml: BAR QQuickItem(0x6000000f48c0, "Bar") qml: BAR QQuickItem(0x6000000f48c0, "Bar") qml: BAR QQuickItem(0x6000000f48c0, "Bar") qml: BAR QQuickItem(0x6000000f48c0, "Bar")
Main.qml:
pragma ComponentBehavior: Bound import QtQuick Window { width: 640 height: 480 visible: true title: qsTr("Hello World") Item { id: bar objectName: "Bar" } Repeater { model: 5 Foo { bar: bar } } }
Foo.qml
import QtQuick Item { property Item bar Component.onCompleted: console.log("BAR", bar) }
Notes:
- "bar" is used for both the id and the property. Changing either the property or the id "fixes" the problem.
- This only occurs if "bar" is an item outside of the delegate component scope (pragma Bound)
