I've had some troubles getting the expected results doing the exercises from http://www.slideshare.net/FI-WARE/io-t-basicexercisesdevelopersweek
No problem when registering a new device, its entity it's also successfully created on Orion CB but when querying for the created Entity non of the device attributes are shown. Created Entity just have TimeInstant attribute.
I get a 200 response code when sending observations but it apparently has noeffect since Entity attributes on CB are missing.

Listing devices

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 to be on image orion-psb-image-R4.2. After launching a new instance (CentOS-6.3init) and installing every component manually the problem seem solved. Maybe a conflict between versions in previous instance.
