pb creating the TemperatureSensorTD using the sample jsonld file

[FanoRamparany]

Hi,
we have got an error message when creating (using POST with the payload containing the content of the TemperatureSensorTD.jsonld found in the "samples" directory) the TemperatureSensorTD. Here is the begining of the payload:

{
"@context": [
"http://w3c.github.io/wot/w3c-wot-td-context.jsonld",
{
"saref": "http://uri.etsi.org/m2m/saref#",
"Sensor": "saref:Sensor",
"Temperature": "saref:Temperature",
"unit": "saref:isMeasuredIn",
"celsius": "http://www.wurvoc.org/vocabularies/om-1.8/degree_Celsius"
}
],
"@type": "Sensor",
"name": "myTempSensor5",
"base" : "coap:///www.example.com:5687/temp",
"interaction": [
{

Here is the error message:

<title>Error 500 </title>

HTTP ERROR: 500

Problem accessing /td. Reason:

        <pre>    javax.servlet.ServletException: No instance of td:Thing found in the RDF payload</pre>
    </p>
    <hr />
    <a href="http://eclipse.org/jetty">Powered by Jetty:// 9.3.6.v20151106</a>
    <hr/>
</body>

when replacing the line "@type": "Sensor",
with :
"@type": ["Thing", "Sensor"]
Or
"@type": ["Thing"]
(found in other TD json files)
It works
We also noticed that the description of the thing (using the GET method) is slimmer than the description we provided (the payload of the POST method)

Any idea why?
