Bindings bug or feature

$

I found a situation, where bindings works not as I expected. If I bind variable someVar to some other variable(s) and also add handler onSomeVarChanged, the handler executes before bindings. Thus, using any non-trivial code in handler onSomeVarChanged is potentially dangerious. You can use some component, that has variable binded to someVar and this variable is not updated yet. See example below: main.qml import QtQuick 2.3 import QtQuick.Controls 1.2 import QtQuick.Layouts 1.1   ApplicationWindow {     id: window       property var currentDate: null       width: 640     height: 480       onCurrentDateChanged: {         print("window.currentDate = " + currentDate)         print("requestManager.date = " + requestManager.date)         requestManager.requestData()     }       RequestManager {         id: requestManager         date: currentDate     }       Button {         text: "Click Me!"         onClicked: currentDate = new Date     } } RequestManager.qml import QtQuick 2.0   Item {       property var date;       function requestData() {         print("requesting data for date " + date)     } } Output (after button click): qml: window.currentDate = Пт сен 19 13:26:24 2014 GMT+0300 qml: requestManager.date = null qml: requesting data for date null
