fiware orion - How to show an entity from in the Wirecloud MapViewer widget

Question

Well I'm trying to show the following entity:

{
  "contextResponses" : [
    {
      "contextElement" : {
        "type" : "City",
        "isPattern" : "false",
        "id" : "Miraflores",
        "attributes" : [
          {
            "name" : "position",
            "type" : "coords",
            "value" : "-12.119816, -77.028916",
            "metadatas" : [
              {
                "name" : "location",
                "type" : "string",
                "value" : "WSG84"
              }
            ]
          }
        ]
      },
      "statusCode" : {
        "code" : "200",
        "reasonPhrase" : "OK"
      }
    }
  ]
}

Wiring NGSI Source and NGSI Entity to Poi operatiors with MapViewer widget (Insert/Update PoI), with the following settings:

NGSI Source

• NGSI server URL: mydirection:1026
• NGSI proxy URL: http://mashup.lab.fi-ware.org:3000/
• NGSI entities: City
• NGSI Attributes: position

NGSI Entity to Poi

• Coordinates attribute: position

But nothing shows up in the map! Can somebody help me figure out what the problem is?

Answer 1

Seems your configuration is correct (I'm assuming mydirection:1026 is a full URL, i.e. includes the protocol), but probably your network is filtering port 3000. Try to use http://ngsiproxy.lab.fi-ware.org as NGSI proxy instead of http://mashup.lab.fi-ware.org:3000/.

Indeed, I recommend you to enable https notifications in your context broker instance and use https://ngsiproxy.lab.fi-ware.org instead, especially if you are creating your WireCloud dashboard in an https web page (e.g. https://mashup.lab.fi-ware.org) as using this NGSI proxy will solve some mixed content problems, see:

• Firefox: https://blog.mozilla.org/tanvi/2013/04/10/mixed-content-blocking-enabled-in-firefox-23/

Update: FIWARE has move from fi-ware.org to fiware.org. The recommended NGSI proxy server is now ngsiproxy.lab.fiware.org (ngsiproxy.lab.fi-ware.org still works).
