Description Ayub Khan 2006-08-02 02:09:41 UTC 
Got following NPE on deleting 'orderDate'attribute from 'purchaseOrder' element.

Steps to reproduce:
1. create purchaseOrder schema
2. In the Design view click purchaseOrder element, then expand attributes, and
select 'orderDate' attribute to show the property sheet for orderDate.
3. Now delete the 'orderDate' attribute. This will cause a NPE, like below.
