error while including SERVICE syntax

[kabulkurniawan]

seems that when including SERVICE syntax, it generates the wrong concrete query i.e. SERVICE syntax was removed!

for example:

REGISTER RSTREAM <s1> AS
SELECT ?s ?lablf
FROM NAMED WINDOW <win2> ON <stream2> [RANGE PT2S STEP PT1S]
WHERE  {
      SERVICE <https://dbpedia.org/sparql> {
                     ?lf  rdfs:label  ?lablf.  }
    WINDOW ?w {
	 ?s   cl:hasLogFamily ?lf.
   	}
  }

it produces these concrete query:

SELECT  ?s ?lablf
FROM NAMED <win2>
WHERE
  { { ?lf  rdfs:label  ?lablf }
    GRAPH ?w
      { ?s  cl:hasLogFamily  ?lf }
  }
