      Description

      Dear Tali,

      A quick question regarding posting events to CEP, I know that the format
      for input events is :

      {"Name":"TrafficReport", "volume":"1000"}

      But, the Orion context broker do generate JSON objects in this format:

      {
      "subscriptionId" : "51c04a21d714fb3b37d7d5a7",
      "originator" : "localhost",
      "contextResponses" : [
      {
      "contextElement" : {
      "attributes" : [
      {
      "name" : "temperature",
      "type" : "float",
      "value" : "26.5"
      }
      ],
      "type" : "Room",
      "isPattern" : "false",
      "id" : "Room1"
      },
      "statusCode" : {
      "code" : "200",
      "reasonPhrase" : "OK"
      }
      }
      ]
      }

      So is there a way to make CEP accept this input event and check that the
      temperature value is between certain threshold this condition:
      TR1.value>0 AND TR1.value<30

      Currently, I am getting this error :

      Could not parse json event org.apache.wink.json4j.JSONException: The
      key [Name] was not in the map, reason: The key [Name] was not in the
      map

      Since there is no Name of course.

      Please let me know if you have a solution or suggestions.

      Best,
      Ahmed Sadek
