Newbie Question: Display fileURLs from FileDialog - getting error from delegate

[cemck]

Hi I'm a QT Newbie, UI Newbie, liking QT Quick but having problem displaying data retrieved with FileDialog. I get an error message from my cfilesDelegate.

console output:
You chose: file:///Users/cmckenzie/Desktop/Beatles/(The Beatles) - Taxman.mp3
qrc:/content/Layouts.qml:86: ReferenceError: url is not defined (repeated 9 times)

I’m using Qt Quick 2 in QtCreator 2.7.2 with Qt 5.1.0.

FileDialog {
id: fileDialog
nameFilters: [ "Music files (*.wav *.mp3)" ]
title: "Please choose a folder or file"
onAccepted: {
console.log("You chose: " + fileDialog.fileUrl)

            cfilesModel.append({"url":fileDialog.fileUrl.string})

        }
        onRejected: {
            console.log("Canceled")
        }

    }

Action {
    id: openAction
    text: "&Open"
    shortcut: "Ctrl+O"
    iconSource: "images/document-open.png"
    onTriggered: fileDialog.open()
    tooltip: "Open an image"
}

ListModel {
    id: cfilesModel
}

Here's where I try to display
GroupBox {
id: gridBox
title: "Folders or Files in Collection"
Layout.fillWidth: true

     TableView{
         id: cfilesView
        model:cfilesModel
        anchors.fill: parent
        rowDelegate: cfilesDelegate
        TableViewColumn {
            role: "url"
            title: "Url"
            width: 240
             }

Component {
id: cfilesDelegate
Row {
Text { text: url }
}
}

Thanks for assistance,

Clara McKenzie
