    Description

      QtQuick 2.0's caching of roleNames triggers a bug in the QSortFilterProxyModel (proxy1) handling of a source model reset signal if the source model itself is also a proxy model (proxy2).

      On setting proxy2's sourceModel proxy1 does not not update its roleNames.

      QtQuick ListView delegates won't correctly display any of the model's data then.

      Proposed fix is to update the roleNames in the reset handler. I'll post a change to gerrit with fix + autotest.
