Appcelerator Titanium Studio 1.0.1: How to show Inspector on OS X Desktop apps?

When I choose to show the inspector inside a desktop app, I get the error below.

As their Wiki said, I've followed this: http://wiki.appcelerator.org/display/guides/Enabling+Web+Inspector+on+Mac+OSX+in+Desktop+1.2.0 But couldn't get it work. I'm sure that I edited the correct file (same as my App ID .plist). Edited with Xcode, added new row, type = Boolean, key = WebKitDeveloperExtras, value = YES.

Every time I click "Show Inspector" (right click menu) I get this error in the console:

"Setting this value to true will allow the Inspector panel to be opened." According to the guide you posted it needs to be set to true not YES.

This isn't really an "answer", except to say that this problem seems to be here and noone's found a decent workaround or solution.

Apart from this question there are also 3 separate questions on Appcelerator's own Q&A site:

• Inspector in Titanium Desktop
• Show Inspector on OS X Desktop apps results an error and
• Show Inspector not launching Web Inspector

The last of which thinks it's been answered by the ~/Library/Preferences/*.plist fix that Brian Huenefeld suggested (which I, elado and other users have found doesn't work.)

The problem seems to affect all my Titanium apps, not just the one I first noticed the problem on, and I've also tried adding the key to Titanium Studio's own Plist file without success.

I've also tried erasing the Plist file, and the Application support folder for the app too, all to no avail.

I don't think I need explain any further how frustrating it is working without the javascript debugger in the inspector panel, especially when studio has no debugging capabilities on its own other than trace!
