Multi value parameters and out proc session state

[Lukasz]

Hi!

In my report I have multi value parameter with default value set to aggregate function AllValues just like described in manual at http://www.telerik.com/help/reporting/designing-reports-parameters-using-multivalue-parameter.html 

I'm using Web Forms report viewer to display that report. It works as expected when using in proc session state. However when I switch to out proc session state report viewer doesn't display report anymore. It gets stuck at "Generating report" message.
Trace.axd shows that request ended with HTTP code 500, but no exception is specified.

There must be a problem with aggregate function handling (builtin functions like First/Last doesn't work either) in Web Forms report viewer because when I set report parameter explicitly:

myReport.ReportParameters["IDs"].Value = new object[] {1, 2, 3}

it works as expected.
However I'd still prefer to use default value and AllValues function approach if it is possible.

Tested with latest internal build 6.1.12.717.

Lukasz

Hi Lukasz,

We were not able to reproduce this problem locally. Please review the attached sample project and see if it works on your side. We will be thankful, if you are able to tell us the exact steps in order to reproduce the problem.

Hi Elian,
thank you for your reply.

It seems that the problem is dependent on development server being used. I'm using IIS Express 7.5 (default configuration).

The project that you attached works as expected when using ASP.NET Development Server (Cassini). However when the server is changed to IIS Express 7.5 (in VS: Project->Use IIS Express) the previously mentioned problem emerges.

I hope this will help you in finding solution to the problem.

Regards,
Lukasz

Hello Lukasz,

We ran some tests again but we were still unable to reproduce the problem, even in IIS Express. If you find any additional info that can help us identify the problem, please share with us. You can also upload a sample project on the net and give us a link, so we can review it.
