Description
When asynchonously loading a component which contains a ComboBox{} element then the following error is produced: "file:///E:/qt/qt56dev/built/qml/QtQuick/Controls/ComboBox.qml:564: TypeError: Cannot read property '__dropDownStyle' of null". When "asynchronous: false" then the error is not produced. The error causes incorrect drawing of the ComboBox (with default and flat styles) and occurs randomly.
Button { onClicked: loader.source = "qrc:/qml/SamplePage.qml"; } StackView { id: stackView } Loader { id: loader asynchronous: true onLoaded: { stackView.push(loader.item); } } Debug output: file:///E:/qt/qt56dev/built/qml/QtQuick/Controls/ComboBox.qml:564: TypeError: Cannot read property '__dropDownStyle' of null
