Summary	0016371: Switching views expands / changes selection
Description	Switching views causes selection to change in two ways: - Browser view tracks selection independently of other views - Switching to a Grid view causes selection to be expanded to include all tracks in a Grid node (rather than the subset of tracks in the node that were originally selected) e.g. 1 In Genres > Alternative [List], select 2 tracks from Album A and 2 tracks from Album B 2 Switch to [List (by album)] --> 4 tracks remain selected 3 Switch to [Browser] --> 0 tracks are selected! i.e. selection in Browser view is completely independent of the other 3 views! 4 Switch to [Grid (by album)] --> 2 albums / 16 tracks are selected ! i.e. MM changes the selection to include all of the tracks on Albums A and Album B!! 5 Switch back to [List] --> 16 tracks are selected!
Additional Information	Originally reported at https://www.mediamonkey.com/forum/viewtopic.php?f=30&t=95367 (item 3) A side effect of this (Preview window changing when switching views) was raised at https://www.mediamonkey.com/forum/viewtopic.php?p=480741#p480741

Fixed in build

From what I see the original issue (item #3 here https://www.mediamonkey.com/forum/viewtopic.php?f=30&t=95367 ) is resolved, because selecting albums in the "Grid (by Album)" keeps the album files selected also after switching to "List" and back to "Grid (by Album)" As for the bug described by Rusty: We have nothing like "partial album selection" in the "Grid (by Album)" view so I am not sure what the solution should be? I see that other apps mostly just cancels/clears the selection after switching the view types. Another choice would be to share the selection only between compatible views (e.g. "List" and ""List (by Album)") But in both cases the original issue reported by Barry would be broken (no longer fixed). So I am not sure what is the expected behaviour here. Moving target to 5.0.1 to collect some feedback at first and then decide.

As to what the expected behavior would be, I would generally expect that items should appear selected if they've been selected: - Selection of a Grid View tile represents selection of all the tracks represented by that tile, so selection of those tracks should therefore persist when switching to other views, and selection of the Tile should persist when switching to a Browser view. - Selection of Tracks in a list view should persist across other views with tracks, and should trigger selection of a Browser/Grid view tile if all the tracks represented by the tile are selected - Selection of a Tile in Browser view represents selection of all the tracks represented by that tile, so selection of those tracks should therefore persist when switching to other views, and selection of the Tile should persist when switching to a Grid view. The main complications with this approach may be in the Browser view because to be consistent with the above: - Selection of Artists tiles should automatically trigger selection of the corresponding Album tiles and Tracks in the view - Selection of Album tiles should automatically trigger selection of the corresponding Tracks in the view I suspect that this may be too complex to implement without causing other issues, so we may have to pursue an implementation that only works one way (i.e. in which Track selections and Tile selections are both persisted, and track selections representing selected tiles are shown for views missing Tiles--i.e. selecting all the tracks in an album wouldn't cause a tile to be selected).

This needs to be reviewed to determine exactly which node-view combinations are problematic.
