Import causes QML Item to not load

[therealmatiss]

Hello! I have a weird problem - whenever I'm trying to import my C++ "backend" to QML, the QML GUI doesn't even load.

I have an application that launches loader.qml from C++, which source is stackview.qml.

Loader QML:

import QtQuick
import QtQuick.Window

Window {
  id: window
  width: 800
  height: 480
  visible: true
  color: "#000000"
  title: qsTr("Test")

  Loader {
    id: mainLoader
    anchors {
      left: parent.left
      right: parent.right
      top: parent.top
      bottom: parent.bottom
    }
    source: "stackview.qml"
  }
}

Stackview QML

import QtQuick
import QtQuick.Controls

import MyApp.Backend // If I comment this out, everything works

Item {
  anchors.fill: parent

  StackView {
    id: mainStackview
    anchors.fill: parent
    initialItem: "screen_main.qml"    

    Connections {
      target: cppStackview
      onChangeScreen: {
        console.log("Screen change to : " + screen_url)
        mainStackview.push(screen_url)
      }
    }
  }
}

Keep in mind, that I'm using import MyApp.Backend in other QML files and it works fine. I guess it's because it's the first .qml file that's being loaded? There are no logs from Qt on this - it simply shows blank screen.

Try running your application with the QML_IMPORT_TRACE set to 1 and look at the messages in the console.
