Hi, could you please let us know when the fix is expected ?

Hello Pavel,

We can confirm that the bug has been reproduced and it is only in present in the SSRS 2005 version. We are now working to release a service pack for SSRS 2005 which will address this issue as well as several other bugs.

It looks as Nevron Charts for Reporting Services 2005 issue only.
RS 2008 handles empty datasets correctly.

Guys, please confirm anyone else can reproduce this.
Thanks

Hi,
I can even reproduce this within sample reports i have installed.
Take 'ChartTypes_Pie.rdl' from 'NRSChartExamples' sample project.
Add 'where 1 = 0' to query to make it look as 'select * from GrossProfitPerContinent where 1 = 0'
Go to Preview.
I can see "NChart Rendering Failed..." exception.

Is anybody able to reproduce this ?

Thanks.

Hi
thanks for your reply.

well...i can simply reproduce this.
In VS 2005 Reporting Service environment I create new report , put nevron chart control on the form and assign it with dataset, drop value & category field. The dataset does not return any record. Then I can see the error while previewing in VS as well as in report viewer on web.
Attaching rdl file (renamed as xml). Hope it can help.

Hi Pavel,

Just tested the control with an empty data set and it was working OK. Can you post the example configuration (chart type + data configuration) that generates the error. If we can replicate the bug it will be fixed within a week.

Hi All,

We are getting the following message within chart area if dataset does not return any records:
NChart Rendering Failed. Exception was: Object reference not set to an instance of a object.

Is there a way to avoid this ?
Thanks a lot.
