XmlListModel: get(int index) method returns undefined.

Yashpal

Hi, I have a problem with get(index) of XmlListModel element, the method returns nothing and so do I see this error.

TypeError: Cannot read property 'page' of undefined

I have written code something like this,

        XmlListModel{
            id: appXMLModel
            source: "qrc:/selectionMode.xml"
            query: "/rss/channel/item"
            XmlRole{ name: "type"; query: "type/string()" }
            XmlRole{ name: "page"; query: "page/string()" }
        }

       ListView{
                id: list_view
                model: appXMLModel
                delegate: appDelegate
                orientation: ListView.Horizontal
            }
            Component.onCompleted: {
                var namePage = list_view.model.get(0)
                console.log("My page " + namePage.page)
            }
        }

And, my xml file looks something like this,

<?xml version="1.0" encoding="utf-8"?>
  <rss version="2.0">
      <channel>
          <item>
              <type>Driver</type>
              <page>qrc:/ItemSelectedFromPathView.qml</page>
          </item>
      </channel>
  </rss>

Tried ListModel against XmlListModel, things are working as expected. Now, I'm totally confused why get(index) method of XmlListModel element doesn't work as expected?

Is your pasted code correct?

XmlListModel{
  id: appXMLModel

but:

var namePage = path_view.model.get(0)

You are calling get() on different object than appXMLModel.

@sierdzio Sorry, it should have been list_view there as id.

@sierdzio So, I was able figure out the root cause. Here, I'm trying to access XmlListModel before it is in ready state. Thank you so much for your support
