[Qt-qml] ListView sections are not updated on item changes

[Michael Nosov]

Hello,

I'm using QML ListView with sections to display content of my own
QSortFilterProxyModel. Seems that sections are not updated when some item in
a list has changed.
I'm attaching test application (based on Qt's abstractItemModel example) to
demonstrate the issue. This application shows list of animals sorted by
name.

- Run ./abstractitemmodel
- Click on 'Set best' for some 'CAnimal' item in the middle of the list
Expected result: 'CAnimal' shall be placed on top of list, Section name on
top shall be 'Best'
Actual result: 'CAnimal' is placed on top of list BUT section names are not
updated

I've found a workaround how to refresh the list - if you set impossible
search criteria, and then unset search criteria - the list will be refreshed
with correct data. But this workaround is not applicable for some reasons.

Does anyone know if I can somehow submit a bug on Qt-Qml against that?

Thanks a lot,
Michael
