My MVC app uses the push model and the CR viewer for reporting. All works great in displaying the report in the viewer however the print/export buttons give the javascript error 'Object not supported by this action'. I am using VS 2008 and MVC. This happens in my dev environment. Any ideas?
The answer to this is so stupid its embarrassing - my popup blocker was causing this error. I did get another error or on th the deployed site however and that was a 404 not found on 'aspnet_client/System_Web/2_0_50727/CrystalReportWebFormViewer4/html/crystalexportdialog.htm'. I just created the folder and on the site and copied the contents of C:\Windows\Microsoft.NET\Framework\v2.0.50727\ASP.NETClientFiles\CrystalReportWebFormViewer4 to it and it fixed it.
