Running OSH locally. To Reproduce

  1. Insert a sensor with this POST: 
    localhost:8181/sensorhub/sos
    <?xml version="1.0" encoding="UTF-8"?>
<sos:InsertSensor service="SOS" version="2.0"
xmlns:sos="http://www.opengis.net/sos/2.0"
xmlns:sml="http://www.opengis.net/sensorML/2.0"
xmlns:swes="http://www.opengis.net/swes/2.0"
xmlns:swe="http://www.opengis.net/swe/2.0"
xmlns:gml="http://www.opengis.net/gml/3.2">
<procedureDescriptionFormat>http://www.opengis.net/sensorml/2.0</procedureDescriptionFormat>
<swes:procedureDescription>
    <sml:PhysicalComponent>
        <identifier>urn:sensor001</identifier>
        <name>My New Sensor</name>
        <swe:validTime>
                          <gml:TimePeriod gml:id="T22">
                                  <gml:beginPosition>2017-06-27T20:35:15.760Z</gml:beginPosition>
                                  <gml:endPosition indeterminatePosition="now"/>
                          </gml:TimePeriod>
                    </swe:validTime>
    </sml:PhysicalComponent>
</swes:procedureDescription>
<swes:metadata>

    </sos:SosInsertionMetadata>
</swes:metadata>
</sos:InsertSensor>
  2. Insert a result template for that sensor with this POST: 
    localhost:8181/sensorhub/sos
    <?xml version="1.0" encoding="UTF-8"?>
<sos:InsertResultTemplate service="SOS" version="2.0"
xmlns:sos="http://www.opengis.net/sos/2.0"
xmlns:sml="http://www.opengis.net/sensorML/2.0"
xmlns:swes="http://www.opengis.net/swes/2.0"
xmlns:swe="http://www.opengis.net/swe/2.0"
xmlns:om="http://www.opengis.net/om/2.0"
xmlns:xlink="http://www.w3.org/1999/xlink"
xmlns:gml="http://www.opengis.net/gml/3.2">
<sos:proposedTemplate>
    <sos:ResultTemplate>
        <sos:offering>urn:sensor001-sos</sos:offering>
        <om:resultStructure>

                <swe:field name="phenomenonTime">
                    <swe:Time definition="http://www.opengis.net/def/property/OGC/0/PhenomenonTime">

                </swe:field>
                <swe:field name="someName">
                    <swe:Quantity definition="urn:ogc:def:property:OGC::Velocity">
                        <swe:label>Some number I came up with</swe:label>
                    </swe:Quantity>
                </swe:field>
            </swe:DataRecord>
        </om:resultStructure>
        <om:resultEncoding>
            <swe:TextEncoding tokenSeparator="," blockSeparator="@@"/>
        </om:resultEncoding>
    </sos:ResultTemplate>
</sos:proposedTemplate>
</sos:InsertResultTemplate>
  3. Insert a result with this POST: 
    localhost:8181/sensorhub/sos
    <?xml version="1.0" encoding="UTF-8"?>
<sos:InsertResult service="SOS" version="2.0"
xmlns:sos="http://www.opengis.net/sos/2.0"
xmlns:sml="http://www.opengis.net/sensorML/2.0"
xmlns:swes="http://www.opengis.net/swes/2.0"
xmlns:swe="http://www.opengis.net/swe/2.0"
xmlns:om="http://www.opengis.net/om/2.0">
<template>urn:sensor001#output0</template>
<resultValues>2017-06-27T21:02:37.625Z,42.123</resultValues>
</sos:InsertResult>
  4. Attempt to retrieve the inserted result with GetResult: 
    localhost:8181/sensorhub/sos?service=SOS&version=2.0&request=GetResult&offering=2017-06-27T20:59:57.100Z-sos&observedProperty=urn:ogc:def:property:OGC::Velocity

Expected Result: The response should be the value 42.123, with no enclosing xml.

Actual Result: The response code is 200 OK, but the response body is empty.

Additional info: I am sure the result insertion was successful, because the GetObservation request works:

localhost:8181/sensorhub/sos?service=SOS&version=2.0&request=GetObservation&offering=2017-06-27T20:59:57.100Z-sos&observedProperty=urn:ogc:def:property:OGC::Velocity&temporalFilter=phenomenonTime,now

Returns the response (200 OK):

The requests posted in this issue had several errors that I fixed directly in the original message. Even after fixing these, I cannot reproduce the problem in the last version, so I'm closing this for now.
