I've been recently moving a project from CF 4.5 to 6.1 and all went well except for CFGrid. I have posted on CF Talk, but nothing definitive yet. Basically at the moment when when i update the grid im getting the following messageError casting an object of type to an incompatible type. This usually indicates a programming error in Java, although it could also mean you have tried to use a foreign object in a different way than it was designedAnyone else out there seen this before?Though i did manage to come across a complete list of all CF hotfix's at:macromedia.com/cfusion/knowledgebase/index.cfm?id=tn_17883
