Issue/Introduction

On a project subobject, there are multiple attributes and this subobject has some subpages. These subpages have display conditions. 

When any change is made to the display condition of the subpages, calculated data type attributes disappear. No impact to other attributes. In order to bring those back, one new calculated data type attributes are created. 

Steps to Reproduce: 

1. Create subobject of the project object.
2. Create calculated attribute on that subobject, for example you can use this something like this DateDiff(created_date,last_updated_date,"")
3. Click on Views->Layout:Edit and create couple of subpages.
4. On one of the subpages add display condition as 1==2, Evaluate and Save and Return.
5. Go back to attributes list and notice your calculated attribute no longer appears.

Expected Results: calculated attribute should not disappear

Actual Results: calculated attribute disappears
