Install the same home screen again 3. Observe Settings -> Home Screens -> Change Home Screen -> home screens selection menu [Actual Result]: Two home screens of the same name [Expected Result]: Only one home screen in the menu [Build Info]: Build ID 20151023005002 Gaia Revision 29ce8ec8606e59f582375234440812b046346513 Gaia Date 2015-10-22 05:31:38 Gecko Revision https://hg.mozilla.org/mozilla-central/rev/1f03a14106e59280761ac53904340f389674337f Gecko Version 44.0a1 Device Name aries Firmware(Release) 4.4.2 Firmware(Incremental) eng.worker.20151023.001128 Firmware Date Fri Oct 23 00:11:35 UTC 2015 Bootloader s1

Nominate for blocking because it creates another bug 1217734.

Hey, let's try to be at least somewhat accurate with these components, eh? :) Homescreen apps are not involved in the process of installing homescreens, application settings or displaying settings. I've moved this to Settings for investigation.

I suspected its WebIDE issue but it does not happen on addon. So there might be some issues when we filter out the homescreen list. @gmarty do you have time to investigate with this?

I'm almost certain this is caused by WebIDE generating a new manifestURL that is different than the one the gaia build system gives the homescreen. In any case, not blocking since it is something only a developer will see and can easily work around.

Comment on attachment 8679453 [details] [gaia] gmarty:Bug-1217730-Duplicated-home-screens-shown-as-separate-home-screens > mozilla-b2g:master I fixed this bug by checking if an app is not already installed before adding it to the list of apps. I also wrote a unit test. Fred, can you take a look at this PR please?

Comment on attachment 8679453 [details] [gaia] gmarty:Bug-1217730-Duplicated-home-screens-shown-as-separate-home-screens > mozilla-b2g:master looks good with 1 thing in github comment. Thanks!

[Blocking Requested - why for this release]:influence homescreen install experience

Agree with Michael and not affecting users. Removing nomination.

Landed in master: https://github.com/mozilla-b2g/gaia/commit/75f2236d36cc9f9c02d3596fae3de014007cfd82

Verified fixed. Same home screen no longer appears as separate home screens.
