Problem with Qt Quick app reconnecting to network after disconnecting

QtQueries

Hi all

My app uses XMLHttpRequests within Javascript to connect to a web service.

The problem we are having is that when the handset loses connectivity and then finds it again, we are unable to make any more successful requests.

Also, we use the Qt Mobility Map object. After losing then regaining connectivity, the Map can no longer display any tiles either.

Here's an example to illustrate the problem

main.qml
Code:
@import QtQuick 1.0
import "NetTest.js" as JS

Rectangle {
id: screen
width: 360
height: 360
Column {
anchors.centerIn: parent
Text {
text: "Callbacks: 0"
id: callbacks
}

    Text {
        text: "Errors: 0"
        id: errors
    }
}

Timer {
    running: true
    repeat: true
    interval: 10000
    onTriggered: {
        console.log("Net test request");
        JS.request(screen.callback, screen.errback)
    }
}

MouseArea {
    anchors.fill: parent
    onClicked: {
        Qt.quit();
    }
}

function callback() {
    JS.numCallbacks++
    callbacks.text = "Callbacks: " + JS.numCallbacks
}

function errback() {
    JS.numErrors++
    errors.text = "Errors: " + JS.numErrors
}

}@
NetTest.js
Code:
@var numCallbacks = 0
var numErrors = 0

function request(callback, errback) {
var xhr = new XMLHttpRequest();
xhr.open("GET", "http://www.google.co.uk", true);
xhr.setRequestHeader("Content-Type", "application/json; charset=utf-8");
xhr.setRequestHeader("Data-Type", "json");
xhr.onreadystatechange = function () {
console.log("Ready state: " + xhr.readyState)
console.log("Resp text: " + xhr.responseText)
console.log("Status: " + xhr.status)
if (xhr.readyState == xhr.DONE) {
try {
if (xhr.status != 200 && typeof errback !== 'undefined') {
errback();
} else if (typeof callback !== 'undefined') {
callback();
}
} catch (err) {
console.log("GetTraffic err: " + err);
if (typeof errback !== 'undefined') {
errback();
}
}
}
}

xhr.send();

}@

run app
observe Callbacks incrementing every 10 seconds
Press power button, select Offline mode
observe Errors incrementing every 10 seconds
Press power button, select General mode

Actual: Errors continues to increment every 10 seconds
Expected: Callbacks increments every 10 seconds

How can we make the app reconnect again?

The problem doesn't happen on the Qt simulator, but it does on the N8.

Thanks
