After a long tap on an app, the removable ones get their (x) icon, but there is no animation and the following errors are in logcat: E/GeckoConsole( 8325): [JavaScript Error: "TypeError: container is undefined" {file: "app://homescreen.gaiamobile.org/gaia_build_defer_index.js" line: 144}] E/GeckoConsole( 8325): [JavaScript Error: "TypeError: draggableIcon is undefined" {file: "app://homescreen.gaiamobile.org/gaia_build_defer_index.js" line: 325}] hitting the home button reverts to standard mode, but also produces this error: E/GeckoConsole( 8325): [JavaScript Error: "TypeError: page is null" {file: "app://homescreen.gaiamobile.org/gaia_build_defer_index.js" line: 228}]

I can reproduce the second error on Buri device using: Gaia b6c5bf1d24230bfed4a8f680e625fa2175001f82 SourceStamp 7ff96bd19c1c BuildID 20130904040205 Version 26.0a1 I am not sure whether Fabrice is reporting using today's build or yesterday's. With the 20130904040205 build I am getting inconsistent behavior when long pressing apps, including some removable apps not showing an x at all when they are long pressed. Eventually after some time the "x" shows up and the animation starts.

To add some additional comments: (1) If you have only one app and you long press it, at first you see no animation. After about 15 seconds the "x" icon finally appears for me. (2) If you have more than one app installed, the "x" appears on all the apps but not the app I long press on. There is a delay but eventually the apps start animating.

I try to reproduce with that build but I guess that the error is not in Home app. I could add more info in a couple of hours

or maybe something added recently that when files are minified are wrong...

Regression from bug 893800

Comment on attachment 800635 [details] Patch v1 I have no idea if this is going to regress anything :). Let's ask the patch author.

Carmen please take a look to this patch, thanks

Comment on attachment 800635 [details] Patch v1 I reviewed it on the PR. What you did shouldn't break anything, but I think just changing if (value !== undefined) with if (value || value === 0) would do the same without adding exceptions to the way the descriptors are treated.

Yes, you are right! Please take a look again before landing, thanks a lot
