             Summary: NPE when trying to use OData service with void functions
                 Key: TEIID-3477
                 URL: https://issues.jboss.org/browse/TEIID-3477
             Project: Teiid
          Issue Type: Bug
          Components: OData
    Affects Versions: 8.10.1
            Reporter: Jaime Meritt
            Assignee: Steven Hawkins
            Priority: Minor


I have Teiid configured to work with OData sources and tested it successfully with the Northwind v2 endpoint.  However, when trying to use my custom OData service I get an NPE during the metadata import process.  After some debugging I have tracked this down to a null returnType coming back from the following code in the ODataMetadataProcessor which will see a null for void functions.  I looked for a translator property to suppress import of procedures to work around it but have yet to find anything that will help so I think this requires a code change to workaround.
 
// add return type
EdmType returnType = function.getReturnType();
if (returnType.isSimple()) {
  mf.addProcedureParameter(...
}
 
Appreciate any help you can provide.  Thanks, Jaime
