How to access an item inside a Tab

[dmendizabal]

I have a TabView and I need to access the items inside the Tabs from outside the TabView. Let me clarify with an example below:

@TabView {
id: tabView
anchors.fill: parent
anchors.margins: 4
Tab {
title: "Tab 1"
ListView {
id: listView
......
}
}
}

Label {
text: listView.currentIndex
}
@

When executing the app, the Label doesn't show anything and there is an error saying that listView isn't defined. Is there anyway to access listView?
So far I'm using a property defined inside Tab to set and get the currentIndex from ListView.
