Occasional dbx.js cookie-related JS error

[Viper007Bond]

From time to time, I get a Javascript error from dbx.js and the only way to fix it delete the cookie. No idea what causes it, but it seems to happen randomly and has been happening for quite some time. I'm using Firefox and it happened on both 1.5.x and 2.0.

Here's the Javascript error that occurs:

Error: this.cookie[i][1] has no properties
Source File: http://localhost/wordpress-2.0.x/wp-includes/js/dbx.js
Line: 6

The cookie is dbx-postmeta and it happens on both my local server and my blog (I think, hard to remember).

When you say for some time, do you recall if you saw it prior to 2.0.5 ?

Yes, it's been happening for a couple versions now.

Clarification: 1.5.x and 2.0 are WP version numbers, not FF numbers, right?

I'm no JS guru, but I think this happens when you try to access the cookie's values when the cookie isn't set, so you might be able to fix it by checking <<<this.cookie>>> first.

I mean FF versions. This JS didn't exist in WP v1.5.x. ;)

Doh! Also note that in that comment I forgot the code syntax for Trac. It was late.

It appears that we're using DBX 2.01 but 2.05 is the current version. Maybe upgrading will fix that error. Patch coming.

Patch for branches/2.0/

There's a patch for /branches/2.0/

Trunk is already using DBX 2.05

Viper007Bond: have you experienced this problem while using 2.1 or WP.com?

Ping Ryan/Andy:

Can DBX be upgraded independently of TinyMCE? The commit that upgraded DBX in trunk also upgraded TinyMCE. What's the rating for updating DBX on the "potential breakage meter" ?

We also need a 2.0.7 milestone already.

Let's put this off until 2.0.7 If we get to 2.0.7 and no one has seen this issue pop up in 2.1, then we'll know that a DBX upgrade is the cure.

Haven't had it happen in 2.1, just had it happen in latest 2.0.x.

The problem I have noticed is if you install Wordpress twice in the same domain/sub-domain. If that happens, the cookies from both installs conflict with each other. This problem only seems to occur on 2.0.X. The 2.1 branch is not affected (I have 3 copies on the same domain with no problem).

We'll look at a DBX upgrade for 2.0.7

I've just updated dbx.js from 2.01 to 2.05 and that fixes the problem for me. I'm currently on WP 2.0.9

DBX 2.0.5 has been in 2.1 for a long time without any complaints. I think this is safe.

(In [4957]) Upgrade DBX to version 2.0.5 to fix occasional cookie error. fixes #3397

DBX 2.05 seems to cause severe bug #3895: Reloading the post editing screen in Firefox turns a post from Published to Private

Reverting. No longer considering this for 2.0.x
