But doesn't seem to be environment related
I'm trying out the Technical Preview of the QtQuick.Controls 2.0 known at the moment as Qt.labs.controls 1.0.
As you can easily customize those new controls, putting a customized ComboBox in an asynchronous Loader makes it to not appear at all, printing this message in the console :
I found out that customizing any of the available properties (even separately) triggers the bug, exception for delegate.
Here's minimal code to reproduce the bug :
I attached a .zip file with extended code proving that my customizations works well when using a standard Loader.
If you try out the attached example, you'll also notice that for a standard ComboBox in an asynchronous Loader, the first element of the model won't show upon completion of the component, you need to select it yourself.
