fiware - Missing attributes on Orion CB Entity when registering device through IDAS -

i've had troubles getting expected results doing exercises http://www.slideshare.net/fi-ware/io-t-basicexercisesdevelopersweek

no problem when registering new device, entity it's created on orion cb when querying created entity non of device attributes shown. created entity have timeinstant attribute.

i 200 response code when sending observations apparently has noeffect since entity attributes on cb missing.

listing devices

• url: /iot/devices/14:da:e9
• method: get

json

{ "device_id": "14:da:e9", "entity_name": "thing12", "entity_type": "thing12type", "protocol": "pdi-iota-ultralight", "timezone": "europe/madrid", "attributes": [     {         "name": "weight",         "type": "double",         "object_id": "weight"     },     {         "name": "valid",         "type": "boolean",         "object_id": "valid"     } ], "service": "openiot", "service_path": "/" } 

querying cb

• url: /ngsi10/contextentities/thing12
• method: get

json

{ "contextelement": {     "type": "thing12type",     "ispattern": "false",     "id": "thing12",     "attributes": [         {             "name": "timeinstant",             "type": "iso8601",             "value": "2015-06-25t13:07:18.354970z"         }     ] }, "statuscode": {     "code": "200",     "reasonphrase": "ok" } } 

the problem seems on image orion-psb-image-r4.2. after launching new instance (centos-6.3init) , installing every component manually problem seem solved. maybe conflict between versions in previous instance.
