894036 - require('window/utils').open creates empty window, when called without explicit features

Status: RESOLVED INCOMPLETE

(Add-on SDK Graveyard :: General, defect, P3)

Description

[Ralf Strobel]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:22.0) Gecko/20100101 Firefox/22.0 (Beta/Release)
Build ID: 20130618035212

Steps to reproduce:

require('window/utils').open() called without any arguments on SDK 1.14, FF 22.


Actual results:

The created window was completely empty (no user interface elements).

Upon code inspection, the reason is that serializeFeatures() defaults to an empty string instead of null, which is expected by windowWatcher.openWindow() to create a standard window.


Expected results:

I expected this call would default to creating a new standard browser window, equivalent to:
windowWatcher.openWindow(null, 'chrome://browser/content/browser.xul', null, null, null);

This opens a top-level window, I might argue that with no URI it should just throw an exception but I can understand defaulting to the default app UI.
