Odd behavior when passing value through WorkerScript

owenzhao

Please see the code first.
main.qml
@import QtQuick 1.1

Rectangle {
property real t1 //: value
Component.onCompleted: {
t1 = new Date().getTime()
}

Loader {
    id: dialogLoader
}

WorkerScript {
    id: testWorkderScript
    source: "test.js"
}

width: 360
height: 360
Text { id: text
    text: qsTr("Hello World")
    anchors.centerIn: parent
}
MouseArea {
    anchors.fill: parent
    onClicked: {
        console.log("t1 is  " + t1)
        testWorkderScript.sendMessage({'t1': t1})
    }
}
function test(t1, t2, t3) {
    text.text = t1
    console.log("ti, t2, t3 is " + t1 + ", " + t2 + ", " + t3)
}

}@

test.js**
@.pragma library

WorkerScript.onMessage = function(message) {
console.log("message: t1 is " + message.t1)
}@

my result in qt creator:
@[Qt Message] t1 is 1339228771545
[Qt Message] message: t1 is 1339228815360
[Qt Message] t1 is 1339228771545
[Qt Message] message: t1 is 1339228815360

[Qt Message] message: t1 is 1339228815360
[Qt Message] t1 is 1339228771545@

It seems that WorkerScript recall the new Date().getTime() when it run the first time. Why?

It may related to a closed bug https://bugreports.qt-project.org/browse/QTBUG-14666
I also file a bug myself.

Currently , the only way is using parseInt() and toString() together, like
@parseInt(new Date().getTime().toString())@

This seems not working each time. A better idea is to use
@property string t1@
then convert it int in the test.js
@parseInt(t1)@
