Have an issue in exporting a slightly complex report to excel from an rdlc. Exporting a simple tabular report works fine, but getting a null reference exception with a more complex one.
As is usually the case, it works on the server in the development environment, but not in the test environment. The server in the development environment has iis, sql and sql reporting services on it and test only has iis (I didn't set them up). I'm guessing there is something that gets installed with SSRS that is not installed with just the report viewer.
The report has several parameters going into it and a few generic lists going in for datasources. Some tables for display as well as a list.
Working with the 2005 version. Exception follows:
