Hi All

Can anyone shed any light on this error that I am now getting after upgrading the site from CMS6 to CMS6 R2?

[NullReferenceException: Object reference not set to an instance of an object.]

Quess you have a property that have an CreatePropertyControl() that don't inherit from PropertyDataControl

Problem solved.

I had a custom PropertyDataControlAdapter and had to override ShouldCreateDefaultControls() to return true to get them to work

Cheers

In my case it was a webcontrol that inherited from PropertyPageReferenceControl : PropertyDataControl. So both custom properties, webcontrols and control adapters can be the guilty who gives the error.
