Data Grid Error Adding new row in version 10.4+

Hi,

After version 10.3.2, I started getting the error message below after saving a new row to a data grid using Entity Framework.

Can you steer me in the right direction? It’s probably my code that needs to be updated, but I don’t know where to look.

Maybe you are aware of something in the 10.4.x update that could have triggered this?

Thanks!

Mike

There is no such known issue. Can you provide runnable code that can replicate it?
