Any expression, for example Globals!PageNumber will do.
In my original report I had a lot of expressions referencing Code and
Parameters, but not the datasource.
I removed everything, now there is only header and footer with some
textboxes left.
As soon as there is any expression other than a literal in one of the
textboxes, the rendering exception occurs.
It's strange, because in other reports there is no problem with expressions
like Globals!PageNumber and rendering to excel.
