Has anyone else encountered an HTTP Code: 500 error while editing an Interface containing only a gridRowLayout?
I have seen this occur several times across multiple different applications. All applications were local installs.
The interface object becomes no longer accessible from the application in /design. The only solution I've found is deleting the object and remaking it.

Update: This happened again, rendering the object completely unable to edit. It was an interface that contained a gridRowLayout() object. The code did not contain an empty a!dropdownField(). When attempting to re-open the object from /design (after salvaging what code I could from the expression editor), it simply gives the same error and does not allow me to see the interface editor at all.
