Specify response for function or action that returns a single null value
------------------------------------------------------------------------

                 Key: ODATA-440
                 URL: http://tools.oasis-open.org/issues/browse/ODATA-440
             Project: OASIS Open Data Protocol (OData) TC
          Issue Type: Bug
    Affects Versions: V4.0_CSD01
         Environment: [Proposed]
            Reporter: Ralf Handl
             Fix For: V4.0_CSD02


With ODATA-412 we decided that a null value has no "stand-alone" representation and instead requests to resource that has the null value return 404 Not Found.

We did not consider actions and functions that return a single value.

For functions it would be somewhat surprising if they would return 404 No Content if the result for a value combination is null. Especially if the function is composable and composing another function that takes this null value and produces a result from it would respond with 200 OK:

GET ~/Foo(1) --> 404 Not Found
GET ~/Foo(1)/Bar(2) --> 200 OK

Also we already define that actions that do not declare a return type respond with 204 OK, and having "sometimes no result" work differently from "always no result" seems odd.
