Last week I updated several farms with SP1 and the June 2011 CU. After updating, several users reported problems with grouped list views. After some investigation, the problems can be easily reproduced:
– Create or open an existing list which contains a grouped view
– Expand one of the groups to show data
– Reload the page
I’ve reported this bug to SharePoint support and we’re working on a solution. Will update here when there is one available.
In collaboration with MS support, we’ve found the cause of the problem and a fix for it. Be aware that this is not an official fix, but one will be made available asap.
Now check the same directory for your language pack, in my case C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\LAYOUTS\1043. Open up the INIT.debug.js file in that folder and notice that the version number now reads 14.0.4762. The language packs contain an outdated version of the js files and that’s what causes problems.
The fix? Just copy the INIT.js and INIT.debug.js files from your 1033 (EN) folder to the other languages available on your system. To be sure, rename the files first (postfix with .bak or something like that) so you can alway restore them when nescessary. Also be aware of the fact that some of the messages this file creates (warnings and stuff like that) will now be in English instead of your own language. I assume the fix Microsoft is creating will copy the proper versions of the affected .js files to the correct folders, in the correct language of course.
The official hotfix is here! Download it here: http://support.microsoft.com/kb/2553117/en-us.
