Status: RESOLVED WONTFIX

(Add-on SDK Graveyard :: General, defect)

Description

[shweta.universidad]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:12.0) Gecko/20100101 Firefox/12.0 (Beta/Release)
Build ID: 20120423122624

Steps to reproduce:

I used the code that's in the mozilla tutorial written in the following link:
https://addons.mozilla.org/en-US/developers/docs/sdk/latest/modules/sdk/panel.html#error

The code is:

var panel = require("sdk/panel").Panel({
  width: 180,
  height: 180,
  contentURL: "https://en.wikipedia.org/w/index.php?title=Jetpack&useformat=mobile"
});
 
panel.show();


Actual results:

At first, this was the error message:
(addon-sdk-1.14)shweta@ubuntu:~/Desktop/my-primero$ cfx run
Using binary at '/usr/bin/firefox'.
Using profile at '/tmp/tmp8Dq5WU.mozrunner'.

    get _viewFrame() this.__xulPanel.children[0],

The code doesn't work and now it shows me the following message:
(addon-sdk-1.14)shweta@ubuntu:~/Desktop/my-primero$ cfx run
Using binary at '/usr/bin/firefox'.
Using profile at '/tmp/tmpbKDSNw.mozrunner'.

Expected results:

It should have displayed the panel like the tutorial says and show no error message!

Are you actually using Firefox 12 like your bug report shows? We don't support running in older versions of Firefox.

And, indeed, support for the for...of loop landed in Firefox 13: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for...of

Please reopen if you can reproduce this on a current version of Firefox.
