Object reference exception [Build 4.2.11.204]

[Jasper]

Hi,

 

I just tried to compile my reporting application (strictly speaking a wrapper) using the latest nightly build (4.2.11.204).
Unfortunately I ran into an "Object reference not set to an instance of an object" exception. The exception is thrown by Telerik.Reporting.dll during report generation, so I am not able to say what exactly raises it.
Do you have any idea what’s going wrong or could you tell me if there are any breaking changes in the interface of Telerik Reporting?

 I just want to avoid running into this issues when using the upcoming (production ready) Q1 2011 release.

 BTW: The project templates for Telerik Reports are vanished from VS 2010 when installing v.4.2.11.204.

 Best Regards

After some further investigation it turned out that the problem was introduced with 4.2.10.1221 (works fine with 4.2.10.1110).

Any Ideas?

[Massimiliano Bassili]

Jasper, a stack trace of the exception will definitely help so try:

• Output window in Visual Studio

• enable the CLR exceptions from Debug, Exceptions menu in VS and run again

Reporting comes with Visual Studio examples - do you get the error when running them?

Cheers

The examples are working like a charm.

Well, this is the output log:
