Unexplainable RTC Report Message

- I removed EVERY FIELD from the RDLC layout and it still gives the error.
- The error comes before the report is even run.
- Searching the text export of the report shows only the one dimensional dataset.
- I even deleted the metadata and it still comes back with the error after recompile.

This must be a Microsoft bug.

Certainly we could rewrite everything. However, I was hoping this would be a learning experience. We have overcome nearly every unanticipated change, undocumented feature, and unexpected problem with RTC report writing. This one makes no sense as the error refers to a variable tag that does not occur in the report. Either it's yet another undocumented message or another obnoxious bug.

It is building the report in VS that leads to this error. The only code I am aware of is in "Report Properties" and is the standard "BlankIfZero", etc. Is there code somewhere else?

Also, I'm not sure what you mean about double clicking on the error. If you run the report the RTC client crashes. You can only see the message from the request page. Double clicking there has no effect. Checking the Event Log gives a stack trace whose verbose nature serves to only overwhelm me with useless information that refers to an anonymous value, "SourceExpression".
