Hi,

Can you please shed some more light on this? Would you please list the sequence of operations that you have executed or send a repro project?

As I sad it works with previous version of controls just fine.

Hi,

I have tried to reproduced the issue on my side, but unfortunately, without any success. Can you please inspect my test project and share whether I am missing something. You can also update it if it is needed and send it back to us via the support ticket that you have opened. I have noticed that the method PopulatePropertiesInitialValues where the exception seems to occur is related to an internal caching mechanism of RadDataForm, so that the issue may prove to be data-related. Would it be possible for you to isolate it in a project that uses your BusinessObject and send it back to us?
