I have a fairly simple SSRS report (just cut and pasted a simple select into Report builder wizard and added a few params, no fancy formatiing, groups, etc.) that does not run when deployed in SharePoint 2010 SSRS. I get the error below when I click to run after completing the parameters (which are able to get data from the db to populate multi select values fine). When I run the report, nothing happens I get a little error exclamation point at the bottom and I click on it and get this message:
---------------------------------------------------------
Message: Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server.
The status code returned from the server was: 500
Line: 5
Char: 62099
Code: 0
-------------------------------------------------------
That is about all the useful information I have been able to find. I have tried adding the things mentioned to the web configs for both ReportServer and Report Mgr mentioned here (http://www.sqlservercentral.com/Forums/Topic1245595-150-1.aspx#bm1334791), but no luck. PLEASE HELP!
