I created a .prpt report with the Report Designer, and previewed the result correctly.
Problem is, after publishing it to the BI Server, every time I open the report from the user console, it's blank.
The BI Server logs an error saying it didn't find a column in the Data-Set, but the column certainly is (the preview works).
What is the problem with the Data Source?
I'm using the latest community versions of these tools (Mondrian 3.3).
