Show Applications button does not bring up application after setting show-favorites to false

[David Chen]

[Description]
This happens on Ubuntu 20.04 LTS. Show Applications icon does not bring up application list, if show-favorites is set to false for Ubuntu-dock. Same problem happens if user manually removes all favorite icons from dock.

[Impact]

 * When users don't want to see favorite app icons on dock, but only see opened apps, they use gsettings to hide favorites, Show Applications icon will not work correctly.

 * Issue seems to be fixed in latest Ubuntu release already, and since Ubuntu 20.04 is an LTS release, it's worth investigating if fix can be applied.

 * Users can have more freedom to customize their Ubuntu desktop to meet their needs.

 * Error message:
gnome-shell[2110]: JS ERROR: TypeError: Main.overview.viewSelector._activePage is null
                                                        _onShowAppsButtonToggled@/<email address hidden>/docking.js:1912:25

[Test Plan - Reproduce steps]

 * Set show-favorites to false by following command:
gsettings set org.gnome.shell.extensions.dash-to-dock show-favorites false

 * Log out/in or reboot

 * Click on show applications button

 * Observe it does not bring up applications

[Expect results]
Show Applications button can bring up application

[Actual results]
Show Applications button does not do anything, applications won't show up

[Environment]
OS: Ubuntu 20.04.2 LTS
Gnome-shell version: 3.36.7-0ubuntu0.20.04.1
gnome-shell-extension-ubuntu-dock version: 68ubuntu1~20.04.1

Performed the same action with 21.04 on the same device, no such problem, application can show up correctly when Show Applications button is clicked.

Thank you for taking the time to report this bug and helping to make Ubuntu better. However, I am closing it because the bug has been fixed in the current version of Ubuntu.

This is a significant bug in Ubuntu. If you need a fix for the bug in previous versions of Ubuntu, please perform as much as possible of the SRU Procedure [1] to bring the need to a developer's attention.

The issue is on a non standard configuration so might not be a candidate for a stable update

[David Chen (david.chen)]

@seb128, thanks for your comments. You mean setting show-favorites to false is not a standard configuration?

[David Chen (david.chen)]

Should the status be "Confirmed" instead of "Fix Released" since Focal is still having the issue?

[Sebastien Bacher (seb128)]

let's be realistic while it would be nice to fix we don't have the resources to commit to it, we could still help uploading if someone want to work on cherry picking a fix though

[Daniel van Vugt (vanvugt)]

It might be less contentious to just delete the Focal task.
