webapp: alt-tab gets "stucked" on the browser rather than going to the next entry

[Sebastien Bacher]

[Test Case]

1. Run firefox
2. Enable webapp integration for a website (e.g launchpad)
3. Go to that website
   -> You get a launchpad icon in the launcher)
4. Open a second firefox (e.g middle click on the launcher icon)
5. Select launchpad in the launcher
6. Press alt-tab once
   -> It should cycle to whatever was selected before

[Regression Potential]

Broken alt-tab behaviour.

Original description:

Using quantal with unity 6.8:
* run firefox
* enable webapp integration for a website (e.g launchpad)
* go to that website (you get a launchpad icon in the launcher)
* open a second firefox (e.g middle click on the launcher icon)
* select launchpad in the launcher
* press alt-tab once, it should cycle to whatever was selected before, instead it keeps cycle on the firefox/launchpad entry

It looks like the entry is counted as two (firefox and webapp-icon) and that alt-tab tries to handle them as different items when they are not

Seb I can't reproduce the bug on trunk., can you confirm?

[Stephen M. Webb (bregma)]

I still get this in raring 2013.02.06.

[Christopher Townsend (townsend)]

I seem to be able to reproduce this in Raring, but not in Quantal.

[Christopher Townsend (townsend)]

So I believe this is indeed fixed in Quantal in version 6.10.0-0ubuntu1 by this changelog entry:
- Changes the swapping order of the detail mode. Now the currently
      active window gets moved to the end, instead of getting swapped
      with the last used window (LP: #1061229)

This is a backport of http://bazaar.launchpad.net/~unity-team/unity/trunk/revision/2827

Now, in Raring (and trunk), this was changed (and caused a regression) by this commit: http://bazaar.launchpad.net/~unity-team/unity/trunk/revision/3096

I will look into how to get the regression fixed properly in trunk and also check with folks to make sure Quantal is now indeed fixed.

[Christopher Townsend (townsend)]

The MP for this bug fixed this issue until revno. 3153 [1], so we went ahead and approved the MP because it was still needed. We decided to remark this In Progress to try to figure out what caused the regression with 3153. However, bug #1129372 was entered yesterday and fixed and I have confirmed that this is now working. Marking this bug back to Fix Committed.

I will also get an MP ready for the Unity 6.0 branch in order to try to get this SRU'd for 12.10.

I still cannot reproduce this in Quantal with the latest Unity. Could the bug reporter or someone else verify if this is the case for them?

I'm going to mark the Unity/6.0 task as Incomplete pending more info before I close this as Invalid.

[Christopher Townsend (townsend)]

Ok, so my test was in a Quantal VM which seems to hide this issue (for whatever reason). On a bare metal install, it has been confirmed that this issue still occurs.

I will push a test branch and have a go at it.

[Stephen M. Webb (bregma)]

Fix Released in Unity Unity 7.0.0 "R series".

[John Lea (johnlea)]

@townsend; could you re-test and confirm that this issue is now fixed in 13.04? Thanks!

[Christopher Townsend (townsend)]

@John Lea,

I just confirmed on 2 different fully updated 13.04 systems that this issue does not occur.

Are there problems still being reported about this behavior?

[Barta Tamás (barta-tamas-d)]

In 13.10 this issue still occurs. I was upgrading from 12.04 every release, and it never was fixed to me.
