Click actions "previews" and "minimize-or-previews" are broken

Can confirm. In order to see the previews you have to right-click on the application icon and then click on 'All Windows' in order to see the window preview. Previously the previews would be shown when left clicking on the application icon.

The latest version of Dash to Dock released on 17th October retains the expected functionality so an issue specific to Ubuntu Dock.

Upstream report:
https://github.com/micheleg/dash-to-dock/issues/1545

Here is the solution ( and the cause of the bug ):

In /<email address hidden>/appIcons.js at line 472:

change
const singleOrUrgentWindows = windows.length === 1 || !hasUrgentWindows;
to
const singleOrUrgentWindows = windows.length === 1 || hasUrgentWindows;

(basically removing the ! sign before hasUrgentWindows)

Then log-out & log-in again.

Thanks Pepijn, that small deletion does seem to fix the issue.

I committed the solution here:

https://git.launchpad.net/~pbgrd/ubuntu/+source/gnome-shell-extension-ubuntu-dock/commit/?h=ubuntu/devel&id=d64317c4faa07a7c42b478db2027561c7933aa13

How does this 'fix proposing' work exactly?

Thanks in advance.

Sorry Pepijn, the code of the dock is managed via github at https://github.com/micheleg/dash-to-dock/tree/ubuntu-dock

Should do a PR there, but I will handle it in next upload.

Thanks!

With this the preview bug has been fixed.

I performed both tests from the bug description:

1. gsettings set org.gnome.shell.extensions.dash-to-dock click-action "previews"
 - Open multiple windows for an application
 - Click on the icon, previews should be shown

2. gsettings set org.gnome.shell.extensions.dash-to-dock click-action "minimize-or-previews"
  - Open multiple windows for an application
  - Click on the icon, previews should be shown
