Problem A: 1. Open a folder in Details View. 2. Press Ctrl+I, add a filter that removes some items. 3. Enable the "Permissions" column. 4. Clear the filter. 5. Note that the previously filtered items have an empty "Permissions" field. Problem B (more difficult to reproduce in the GUI, but easily unit-testable): 1. Open a large folder in Details View. 2. Enable the "Permissions" column ("User" and "Group" will also do, but it is important that there are files for which these fields differ). 3. Hide some items with the filter bar. 4. Switch to "Sort by Permissions/User/Group". 5. Clear the filter. 6. Note the incorrect sort order. There is a patch at https://git.reviewboard.kde.org/r/114266/.

Git commit 2260d70e21ad8ff49dc62bc096c7e5bbce9f0efe by Frank Reininghaus. Committed on 14/12/2013 at 10:51. Pushed by freininghaus into branch 'KDE/4.12'. Update the roles for filtered items if necessary Since Dolphin 4.11, we store not only KFileItems, but also the corresponding ItemData struct for filtered items. This is required for keeping track of the parent-child relationships, and has the nice side effect that the ItemData need not be re-determined when the items are shown again. However, this can become a problem if the visible roles or the sort role change while some items are filtered. This is fixed by is fixed by clearing the QHash "values" for the filtered items if the visible roles change. The hash will be re-populated with all requested data as soon as the items are shown again and the data(int) method of the model is called. Moreover, before the items are inserted into the model after filtering, we have to make sure that the sort role "Permissions"/"User"/etc. is present in the hash "values". This is achieved by factoring out the code that currently does this job for new items in createItemDataList() into a new function, and calling this in insertItems(), because the same treatment is required for the previously filtered files.
