We have converted your thread to private, so that you are able to send files safely. In particular, we have asked if you can provide a project that is reproducing the error, as it seems it is a result of some specific setup in your solution. The thread is available in your account - you should be able to access it once you log in to the Telerik site.
Let us know if you have any problems accessing the converted thread. Of course, we are going to post here as well the final answer once the requested files are analyzed and we have a resolution for your issue.
I am looking forward to your feedback in the support thread.
the Telerik team
