Indeed you are correct about the behavior you have described. However, we have address it and I have attached a internal build which contains the fix. I have updated your telerik points too.
hi Rosen,
in my case, this hot fix did not resolve problem. it still sending data items not included in my editor template.
I also used the other hot fix posted in this forum (v2011.1.323), still ajax editing is broken. Can you share the latest internal build that will fix this issue? Thanks!
