1.2.3, GetDisplayName(), the Saved Variables and a experimental fix

zgrssd

With Update 1.2.3 Zenimax accidently broke the proper working of the GetDisplayName() function. It is on the list of know bugs (under UI), but might take some time to fix: http://forums.elderscrollsonline.com/discussion/114325/patch-v1-2-3-known-issues/p1 (it was not even planend for the 1.2.5 patch).

Without that function, the Saved Variable system (among others) is unable to get the right account name and tries to store/read data from a account named "" (empty string). While this does work ("" is a valid entry), it means pre-patch saved data is inaccessible (unless you followed Cairenn's guide to save it: http://www.esoui.com/forums/showthread.php?t=1843) and that all accounts logging in under the same windows user will share thier global settings (character wide settings are still hidden behind the character name).

The ESOUI community managed to cobble together a fix:

It replaces the currently buggy version of GetDisplayName() with a version that works in many cases (see behavior for details). However if you install it you will have to manually edit your saved var files (or live with returning to the data last used before 1.2.3 patch).
It is designed for minimal processing cost, turning off once it is no longer needed and maximum amount of cases covered.
Also we have extensive tested it and thought this through. Still it is going into a area Addons normally should not enter. So I can't guarantee for anything:
At best using it means that once Zenimax fixes GetDisplayName() you won't have to rework your saved variables then. But can instead to it now in peace.
At worst it might break something of the ingame functionality (as usual for addons, it cannot affect anything before you log in with a character).
