Can't display report: Report is unavailable or session has expired.

[MJDS]

Hello all, I'm using Telerik Report for the first time. Since we use other Telerik solutions, we opted to try it.

Here is my current problem. I created the Service in my server, where all my solution services are. I created a ClassLibrary with the report, and followed the tutorial to create the viewer in my Silverlight application. Now when I try to render/view the report I get an error: "Report is unavailable or session has expired."

I debugged my server, and both the report, and the data source (an object) are created. The report works fine in design preview. I checked asp.net session, and tried both StateServer and InProc sessions with the same error. 

As someone suggestion in this forum, I debugged with Fiddler and two calls are made, with the following response:

Fist call response:

     </GetPageResult>
   </GetPageResponse>
  </s:Body>
</s:Envelope>

But the above response did not help me solve the problem. What should I do, where should I look?

Hello Mjds,

The general reasons for this error are listed in the Report is unavailable or session has expired error message KB article. Additionally you can debug in VS with first chance exceptions enabled against the same version of IIS instead of Cassini and check the VS output and Event viewer for any errors. Give it a try and if you still experience any difficulties we will appreciate if you send us the problematic runnable project and more information on your deployment environment to debug locally.

Best wishes,
Peter

Hello again, and thankyou for your reply.

I did the VS configuration, and created a new app with the report, and my enviroment configuration. Aparently the problam was the Security Mode, I use our implementation of all access/membership controls, and had to set everything to TransportWithMessageCredential, the problem was in the WebHttpBinding, I set it to TransportCredentialOnly and it worked:

<bindings>
  <basicHttpBinding>
    <binding name="TelerikBasicHttpBindingConfig">
      <security mode="TransportWithMessageCredential"/>
    </binding>
  </basicHttpBinding>
  <webHttpBinding>
    <binding name="TelerikWebHttpBindingConfig">
      <security mode="TransportCredentialOnly"/>
    </binding>
  </webHttpBinding>
</bindings>
