Last week, Microsoft released Dynamics 365 for Finance and Operations, Enterprise edition Platform Update 9. After the release, we found a critical bug in the platform that was causing forms and tables authored using extensions to throw an error when they were opened. This was due to a bug in the compiler logic that generated incorrect code for forms written via extensions. This issue has now been fixed and a hotfix has been released on Issue Search as KB 4038216. In addition, all places where Updates 9 was made available such as the downloaded VHD on Connect ,Tier 1 and Tier 2 deployments via LCS and Update 9 package on Asset Library in LCS have been updated with a new build of Platform Update 9 (7.0.4612.35162) that has the fix for this issue. Anyone that has taken Platform Update 9 with an older build than 7.0.4612.35162 should take the update for this critical bug to avoid getting errors.
