Public bug reported:

If using APL and setting the primaryPageSource:
Qt.resolvedUrl("MyPage.qml) the APL is so slow to load that the
primaryPage value doesnt exist until way after the component.oncompleted
signal is emitted.

I came across this issue when using the contenthub. if i select a file
in Telegram for example and my app recieves the transfer it tries to add
a page to the APL: addPageToCurrentColumn(pageLayout.primaryPage,
Qt.resolvedUrl("MyPage2.qml"))

Error:

qml: No SourcePage specified. Page will not be added.


Note: setting primaryPage: MyPage{} works without issue and resolves. 

Example:

import QtQuick 2.4
import Ubuntu.Components 1.3


MainView {
    objectName: "mainView"
    applicationName: "aplTest.Testers"

    width: units.gu(100)
    height: units.gu(100)

    AdaptivePageLayout {
        id: apl
        anchors.fill: parent
        primaryPageSource: Qt.resolvedUrl("UI_FileOne.qml") //<-- qml: No sourcePage specified. Page will not be added.
        //primaryPage: UI_FileOne{} //<-- This works

        layouts: [
            PageColumnsLayout {
                when: true;
                // Just a single column layout
                PageColumn {
                    fillWidth: true
                }

            }
        ]

        Component.onCompleted: {

            apl.addPageToCurrentColumn(apl.primaryPage,
Qt.resolvedUrl("UI_FileTwo.qml"));

        }
    }//AdaptivePageLayout

}//Mainview
