g_instanceid is undefined in Meeting Workspace
During the testing phase of our new deployment of sharepoint 2010 I ran into the following problem. We were setting up a site collection for our user were they can set-up team sites and workspaces. After linking a few Outlook meetings to the workspace we noticed that the date selection menu on the left wasn't functioning any more. IE8 gave us an error:
Message: 'g_instanceId' is undefined Line: 2 Char: 150142 Code: 0 URI: http://<server_name>/_layouts/1033/core.js?rev=c3ROI4x%2BKHVTMbn4JuFndQ%3D%3D
A quick google-search lead me to a technet page which suggested the following solution.
Place the following line of code in the top part of your master page file (eg. v4.master):
<%@ Register Tagprefix="Meetings" Namespace="Microsoft.SharePoint.Meetings" Assembly="Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>
And place this after the <body> tag:
<Meetings:PropertyBag runat="server"/>
This solved the problem for me
