delete derived table from domain

[sheva2]

We tried adding a derived table to a domain and realized this was not the best way to do this. Now we would like to delete the derived table. We have never referenced it anywhere else but when we try to delete we get this in the log:

 2017-01-13 15:10:49,761 ERROR DomainValidatorImpl,http-nio-8080-exec-7:323 - Unexpected exception during domain validation: NullPointerException: null

Any ideas?

This happens when you want to save the domain after you made changes ? 
  You do not get the error immediatly after you try to delete the derived table ? 

There might be something else wrong with your domain. It might not be the derived table that is causeing the issues.

Make sure that your deleted any Sets and Items (under the display tab) thats value was referenced from Derived Table.  

Kind Regards
