rsDataSourceNotFound error in SSRS 2005

As soon as a report is re-deployed a refresh of the report in the viewer shows the following error message:

An error has occurred during report processing. (rsProcessingAborted)

The data source 'xxx' cannot be found. (rsDataSourceNotFound)

This error occurs irrespective of electing to re-deploy or not re-deploy the datasource, and the only solution seems to be to close the report viewer down and restart it.

Under RS2000 any changes that were made to a report, would automatically be shown to the user if the report was refreshed, without having to close the browser/application down and restart it.

How do I get around this error?

Pl let me know if anyone has encountered this error?

rs:ClearSession not working

the report data does not refresh even though i added the rs:ClearSession parameter to the URL..i have to click the refresh button to get the latest data..

the URL i use:

http://localhost/Alcon/Reports.aspx?rs:ClearSession=true&distCd=DPI&SOSummary=true

any ideas on how to solve this problem?

What is Reports.aspx? Is that your custom application?|||

yes, thr Reports.aspx is the pageviewer actually..

i already solve the problem... but the solution was a bit weird... i have to add the rs:ClearSession to the parameter of the report and not on the URL.
