"Object reference not set" in StiComponentV2Builder

[John]

Hallo Support,

I recently added a new version of your dlls to our project and, on testing discovered that I now receive an error for certain of our reports.
Firstly, here are some details:
Error: Object reference not set to an instance of an object
Occurs in: Stimulsoft.Report.Engine.StiComponentV2Builder.Render
file version - 2014.3.17.0
Runtime version - v4.0.30319

The only dlls we use are Stimulsoft.Report and Stimulsoft.Base. In version 2014.3.7.0 everything works fine.
Unfortuately, I do not get any further information on the error. I cannot see which line of code in the Render method causes it.

Now I'm not sure what to do. Normally I'd send you a test project with an example. However, in this case, the report is being created dynamically at runtime in c#. It is very embedded in our whole solution and although I saved the c# code and data source whilst debugging, by using these files in a separate test project I was not able to reproduce the issue.
The report itself produces a table with a lot of icons and I am not using a template for creating it.

Have you had problems recently with the "Render" method?
Do you have any idea what I could do to solve this?

Thanks very much.

Hello Alexsey,

In the attachment you more or less see where abouts it is crashing. I added the StiComponentV2Builder class by reverse engineering for testing.

I hope this helps you.

Best regards,
