Upgrading from Q1 2014 to Q2 2015 Parameter Issue

[Mike]

I recently upgraded from Q1 2014 to Q2 2015 and now I am having issues on any reports that I prompt for parameters. In the past when I opened the report, I would get an error, but the user could enter the parameters and then properly run the report (See ss1.png). Now I just get an error and no parameters (see ss2.png). Here is what I use for my display code in my MVC Razor page:

 

         @(Html.TelerikReporting().ReportViewer().Id("reportViewer1").ServiceUrl("/api/reports/").TemplateUrl("/scripts/reportviewer/templates/telerikReportViewerTemplate-9.1.15.624.html").ReportSource(new TypeReportSource() { TypeName = "PortalReports.HelpDesk.DeptTicketSummary, PortalReports"}).ViewMode(ViewModes.INTERACTIVE).ScaleMode(ScaleModes.FIT_PAGE_WIDTH).PersistSession(false))

 

What am I missing? The only thing that has changed is the version.

I want to make sure I am clear. I want the user to enter in parameters before running the report.

I figured out I needed to add .ParametersAreaVisible(true) to the the Html.TelerikReporting().ReportViewer(), then it works like before. However, is there a better practice so that error message won't show at all?
