Created attachment 122636 [details] Picture of issue SUMMARY Filter bar does not clear last result IF you have a folder expanded STEPS TO REPRODUCE 1. bring up a directory list then use filter to constrain to an entry 2. expand the directory entry 3. clear the filter term then do another search to constrain to an entry 4. the original 'opened' folder remains in the view OBSERVED RESULT EXPECTED RESULT SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
Happens to me on current version. I'm updating the version and changing to CONFIRMED. You can actually reproduce it by simply expanding some folder before filtering, then filter by some nonsense string "asdasdasd" than should yield zero results, but the folder you expanded will show as a result.
I found the bug: void KFileItemModel::applyFilters() in the file src/kitemviews/kfileitemmodel.cpp. The algorithm creates the bug on purpose, but it doesn't have to. I'll try to fix it over the weekend. Assigning to myself.
