Description
When using a Loader component combined with a bound property, the compiler claims that this is not compilable, spitting a couple of warnings/errors. So
Loader {
id: loader
readonly property int foo: loader.item && loader.hasOwnProperty("bar") ? loader.item.bar : 0
}
results in
Warning: main.qml:12:94: Property "bar" not found on type "QObject"
readonly property int foo: loader.item && loader.hasOwnProperty("bar") ? loader.item.bar : 0
^^^
Error: main.qml:12:94: Could not compile binding for foo: Cannot load property bar from QObject of QQuickLoader::item with type QObject.
readonly property int foo: loader.item && loader.hasOwnProperty("bar") ? loader.item.bar : 0
^^^
.
Is there a cleaner way to do it? If there's none, how to get rid of the warning/error?
