Hi
Previously I had this (The source of the report definition has not been specified) error when accessing the report on a page however recently I have had it when looking at the report preview.
Creating a blank test project all was OK on a basic report simply showing a barcode. So I started to match it with my live site and on the second change managed to replicate the issue. My live site is set to compile for x64. The test site is set to AnyCpu, switching that to x64 caused the report preview to fail and display the "The source of the report definition has not been specified". Reverting to back AnyCPU and it worked.
I assume that this is a bug...
Regards
Jon
