If you've loaded August CU for Project Server 2010 – KB 2276341, but haven't loaded either SharePoint Foundation 2010 August CU (KB 2266423), or any of the rollup packages (KB: 2352346, 2352342 or 2352345) then you'll get an error loading the schedule web part and drilling down into a project - or other pages that us the JSGrid.

Description of SharePoint Foundation 2010 hotfix package (Sts-x-none.msp): August 31, 2010
Description of SharePoint Foundation 2010 CU Server Hotfix Package (SharePoint Foundation server-package): August 31, 2010
