> 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.

> EdmType returnType = function.getReturnType();
> if (returnType.isSimple()) {
>   mf.addProcedureParameter(...
> }

> Appreciate any help you can provide.  Thanks, Jaime
