Recently we have released Update 5RC for Visual Studio. And installing this update on TFS server machine cause access issues with TWA backlog screen. When accessing the workitem from TSWA we get various errors on the screen like "TF400898: An Internal Error Occurred.", “Unable to get property ‘setMessage’ of undefined or null reference”
This is as a known issue with Visual Studio U5RC, when this update is installed on the TFS Application Tier machine.
Please do not install Visual Studio update 5RC on the TFS Application Tier machine.
This issue remains even after uninstalling the Visual Studio U5RC from the TFS server machine.
We have started working on the fix for this and would be included in Visual Studio Update 5 RTM.
