Page.head.sections selects the first item even though selectedIndex is -1

[Gustavo Pichorim Boiko]

In some cases it is desired that no header section is selected when the program starts. We used to achieve that by setting head.sections.selectedIndex to -1, but on Ubuntu.Components 1.3 this doesn't work: the first item gets selected by default. See the sample program below:

import QtQuick 2.4
import Ubuntu.Components 1.3

MainView {
    id: mainview
    objectName: "mainView"

    width: units.gu(100)
    height: units.gu(75)

    Page {
        id: mainPage
        title: "Should not select"
        head.sections.model: [ "first", "second", "third" ]
        head.sections.selectedIndex: -1
    }
}

This is actually a regression, the sample program below works fine on Ubuntu.Components 1.2
---------------------------
Update: The old header doesn't work with the new design properly, therefore apps should turn to use the 1.3 hearing as in the example below:
it will work properly when the app switches to the new header:

import QtQuick 2.4
import Ubuntu.Components 1.3

MainView {
    id: mainview
    objectName: "mainView"

    width: units.gu(100)
    height: units.gu(75)

    Page {
        id: mainPage
        header: PageHeader {
            title: "Should not select"
            extension: Sections {
                model: [ "first", "second", "third" ]
                selectedIndex: -1
            }
        }
    }
}

Isn't this similar to bug 1511839?

[Gustavo Pichorim Boiko (boiko)]

That's a different problem, not sure it was a problem introduced by the MR fixing bug 1511839 or if the problem was already there.
Just try the sample program above using the latest UI toolkit (which already includes the fix for the other mentioned bug) and see the problem.

I am still investigating, but I verified that it will work properly when the app switches to the new header:

import QtQuick 2.4
import Ubuntu.Components 1.3

MainView {
    id: mainview
    objectName: "mainView"

    width: units.gu(100)
    height: units.gu(75)

    Page {
        id: mainPage
        header: PageHeader {
            title: "Should not select"
            extension: Sections {
                model: [ "first", "second", "third" ]
                selectedIndex: -1
            }
        }
    }
}

As we also discussed in this bug: https://bugs.launchpad.net/ubuntu-rtm/+source/ubuntu-ui-toolkit/+bug/1517614 there are issues with the Page.head.sections that we cannot fix properly, but we released now a new PageHeader that no longer has these problems.

So from UITK I consider this fixed. The apps still need to update to use the new header.
