Creating reports and dashboards | Stimulsoft community forum

Hi

We have just purchased Stimulsoft Reports WPF and I have upgraded my project from the demo version 2010.2.749 (called SWPF_2010.08.10_D2008) to the latest registered version 2010.2.761 (called SWPF_2010.09.07).

All worked ok with the demo version but now when I call the Designer with stiReport.DesignWithWpf(); I get a last chance exception:

Dispatcher Unhandled Exception
Error: Object reference not set to an instance of object.
Source: Stimulsoft.Report.WpfDesign.

I only get the error if I first register any Busines object.

Stack Trace:

I have gone back to registered version 2010.2.754 (called SWPF_2010.08.24) as this was the closest registered version to my working demo version.

All now works OK again. It seems that something has changed in later version(s) that causes a problem when registering complex Business Objects.

Thank you.

I have checked out version 2010.2.764 (called SWPF_2010.09.15) and the problem is fixed.

Thank you.
