If AJAX is enabled in DNN Host Settings, a client-side error occurs when clicking Update after specifying a Reporting Services server report. This makes it impossible to save the settings unless AJAX is turned off. I have tried this on a couple of sites to check it is reproducable.

DNN version: 4.7.0, Reports version 5.0 with RS visualizer 2.0 installed

Steps to reproduce:

1. In Module Settings > Report Settings > Data Source Settings, enter Title=Any title
2. In Display and Caching Settings, select Active Visualizer=MS ReportViewer, Report Type=Server Report
3. Enter Server Url and Server Report Path (I leave the 3 login fields blank)
4. Click Update
5. IE displays an error, and the page is not submitted:
   Line:76 Char:1 Error: 'null' is null or not an object Code:0 URL:.........

Now turn off AJAX in Host Settings and repeat the above steps. The settings save and the report displays.

Please confirm if this is a bug and if a workaround exists. Should I put this in Gemini?
