Icons in the App scope disappear and appear when search is refreshed

[Michal Predotka]

After installing, uninstalling or updating an app, all the app icons disappear for a second or two. That's annoying and makes me feel like the phone is broken/slow/unresponsive. I believe there are other ways to indicate refresh without disappearing icons.

I've added Unity8 to the list, as it may be possible for the dash to avoid destroying the current view until the new search returns the results, but there is no other way to refresh the list of results in a scope, outside of performing a new search.

Can't you just not clear the model until the new result has come it? I don't think we can make the View keep the data if the model is cleared underneath.

Also, especially for the apps scope, it'd be great if you could diff the query result against the previous one and not reset the model, but apply the diff to it. That way the view could animate when an app shows up or is removed instead of just destroying everything and rebuilding everyhting.

Just wanted to add, I wasn't thinking about "search" functionality when reporting this bug. I admit that I don't understand how the search is involved in disappearing app icons after installing, updating or uninstalling a program.

Status changed to 'Confirmed' because the bug affects multiple users.

[Cédric Bellegarde (gnumdk)]

This behaviour is also present in today scope... Unity 8 need a way to refresh a view on the fly and only refresh what is needed.

Current behaviour is 90's friendly...

By the way, keep up the good work!

@mpredotka The "all" view is just an empty search (ie, "show me all results"). Scopes that provide completely different results for empty search (like the main view of the store scope) just treat the search specially when the search is an empty string.
