There are vulnerabilities in the Report Server related to Cross-Site Scripting.

Getting this error in the browser when trying to preview a report:

Error registering the viewer with the service.
An error has occurred.
Incorrect value (null) deserialized. Make sure you are using CacheStorage inside single-instance application deployment only.

A possible reason is the cache for the Report Server used for previewing reports has become corrupted. A workaround is explained in the Telerik.Reporting.Cache.CacheStorage.AddInSet NullReferenceException KB article.

It will be very convenient for the user to be able to clear the cache directly from the Report Server Manager UI.

It seems that when you try to open two tabs in the same browser looking at different websites, the browser gets confused about the URL that is sending the request. Issue is related to CORS protocol and HTTP caches.

It sounds like something needs to be changed on the report server so that even if it gets cached it would still allow access when I switch sub domains.  Or something on the viewer side to clear the cache.

If you set a default value of integer subreport parameter to '3233' or another valid integer, when executing the main report there will be an exception stating that the value for this parameter is not valid and the report processing is canceled. The parameter exists only in the subreport and not in the main report.

The error disappears if the value of the parameter is set with an Expression, for example, '=3233'.

Thank you for adding this feature.

I tested this feature and found that emails were not being delivered to email addresses in the 'CC' email address field.

Furthermore, would it be possible to look in to these options?
1. Add 'BCC' email address field option
2. Add multiple email addresses under 'MAIL SERVER' in Configuration - This will allow us to add SMTP email services for multiple companies / clients, which can then be utilised in the 'FROM' email field in the Preview Report Email feature.

It is great that Telerik takes on feedback and is continuously updating the software to provide an excellent service to its users.

Thank you.

Though I have overridden the mail template for an individual alert, It is picking up the Configuration | Mail Templates | Data Alert External User for an external email address. However, internal email address gets the right one. 

Please help me resolve this. 

No matter what I try, I get this error when previewing a report:

An error has occurred while processing Report 'SomeReport': Unable to establish a connection to the database. Please, verify that your connection string is valid. In case you use a named connection string from the application configuration file, make sure the name is correct and the connection string settings are present in the configuration file of your application. ------------- InnerException ------------- Format of the initialization string does not conform to specification starting at index 0.

However, everything works great while in the designer.

Any info would help.

Thanks,

The current version of reporting service seems to have issues with the newer servicestack libraries. The only way I could get the ServiceStack Service implementation to work is to use the following dependencies (attached). What is the official supported version of ServiceStack and when will newer version be supported?

The feedback form looks horrendous on Chrome. See screen shot.

I am using Telerik Reports Server Q1 2016. I have two problems while configuring the Authentication in Reports server. 

1. Save button hides behind the footer. 
Am unable to see the save button for the authentication section. I have set the position in the developer tools and makes it visible. 

2.The external authentication settings cannot be validated.
I am getting this error while saving the authentication settings. 
Please refer the sample values i given in the field. 

Enabled: True
Metadata URI : https://customFederationServer/FederationMetadata/2007-06/FederationMetadata.xml 
Relying Party ID : http://mylap-3918:83 (url of the application)
Authority: https://customFederationServer/adfs
Client ID: 1234

When i enter the above details and click on save button, i got an error "The external authentication settings cannot be validated". 

Any information would help. 

Thanks,

Following the ReportServerManual.pdf I meet the system requirements, using Visual Studio 2013 and have followed the installation guide but I am getting the following error when running the report server web application;

"A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 50 - Local Database Runtime error occurred. Cannot create an automatic instance. See the Windows Application event log for error details.
)"

I have checked the application pool identity has permission to the files.
Please advise.  Kind regards, Scott.
