Review request for Dolphin.


Description
-------

When the refreshItems signal is received for an item, we call KFileItemModel::retrieveData(), which updates many of the item's properties. Unfortunately, it also resets the 'isExpanded' state to false. The result is that folders are (partly) collapsed in the view when their contents change.

I propose to fix this by not initializing the 'isExpanded' role at all in retrieveData(). When KFileItemModel::isExpanded() tries to access the non-existing entry in the hash, the default-constructed QVariant evaluates to 'false' anyway.


This addresses bug 299675.

Works for me, old and new unit tests pass.
