I have an entity which has an optional string attribute called "name".
 How can I configure a fetch request for all instances of this entity

However if name is not set, it's not going to be an empty string, so
this also doesn't seem to be what I want.  How can I set up this
fetch?


Type
	name != nil
as an Expression.
