I am trying out using ReportViewer in an ASP.NET MVC project, and it worked well. However, when I introduced a parameter in the report, the ReportViewer failed to display the report. In other words, In ReportViewer you specify the parameter value and hit 'View Report', but nothing is displayed. I tried out retrieving the same report with same parameter value from an ASP.NET WebForms project with ReportViewer, and it worked perfectly fine.
My report is a server (rdl) report hosted in SQL Server 2008 R2.
My MVC project is the same as the best answer of this question, except that I am using a server report with a parameter.
The error is a JavaScript error, here is the full exception stack:

I believe something is missing in my settings. Again, my web.config is the same as this.
