Hi,

I encountered this error message:

QQmlComponent: Component is not ready
file:///C:/Qt/Qt5.4.0/5.4/mingw491_32/qml/QtQuick/Controls/StackView.qml:836: TypeError: Cannot read property 'Stack' of null

I can't find any similar issues around.

And the error message is too vague, is there any way to configure Qt Creator to display a specific error?

Any advise what could possibly the cause of this error. Below is my code on StackView.

Qt Code: 
  1. StackView {
  2.     id: mainStack
  3.  
  4.     function effectivePop(clear) {
  5.       var prevItem = mainStack.find(function(item, index) {
  6.         return ( (item.transitory === undefined || !item.transitory) &&
  7.                  (item !== mainStack.currentItem) ); } );
  8.       if ( (clear === undefined || clear) && prevItem.clear)
  9.       {
  10.         prevItem.clear();
  11.       }
  12.       mainStack.pop(prevItem);
  13.     }
  14.  
  15.     anchors.fill: parent
  16.  
  17.     visible: false
  18.  
  19.     delegate: StackViewDelegate {
  20.       pushTransition: StackViewTransition {
  21.         PropertyAnimation { target: enterItem; property: "opacity"; from: 0; to: 1; duration: 100 }
  22.         PropertyAnimation { target: exitItem; property: "opacity"; from: 1; to: 0; duration: 100 }
  23.       }
  24.     }
  25.  
  26.     Component.onCompleted: {
  27.       push(Qt.resolvedUrl("ConnectionPage.qml"));
  28.       push(Qt.resolvedUrl("Question.qml"));
  29.     }
  30.   }
To copy to clipboard, switch view to plain text mode 

If i'll add an initialItem, there's no error however, it won't display the actual page.

Please advise, thanks.
