Commented Feature: $orderby not working on child entity [583]

when supplying an $orderby parameter which requires the access of a property on a child entity; the returned entity collection is not ordered correctly.<br /><br />example: ~/person?$orderby=address/postalcode,address/premises<br /> <br />
Comments: The current orderby query option suppot only the first level properties. We can revisit this in the future release.
