Server error when deleting doctype property
I get an "Object reference not set to an instance of an object. " when trying to delete properties from documenttypes. Is anyone familiar with this error? It used to work fine...

Hey,
I have experienced similar when my doctypes have been nested - deleting properties from a parent has sometimes caused the above.
Where do you see this error on the doctype admin or the content admin screens?
Thanks,
Chris.
This is from /Settings/Document Types and the doctype is nested :/
How did you get around it?
It's a known error, check http://our.umbraco.org/forum/core/general/6003-Object-reference-not-set-to-an-instance-of-an-object-in-Admin-Backend?sort=newest
is working on a reply...
