UPDATE: 现在问题似乎已在"global" Orion实例中得到纠正 .

我尝试更改实体的属性，但似乎没有想要的效果 . 我记得，相同的代码在2个月前运作良好 . 现在该怎么办？

我在"global" Orion Broker http://orion.lab.fi-ware.org:1026 中使用了float属性 test_1 实体 cie_test_1 . 我知道经纪人的意图是宣传不断变化的 Value 观 . 但是，似乎 Value 无法改变 . 交易细节如下 .

经纪人的版本信息是

{ 
  "orion" : { 
    "version" : "0.19.0", 
    "uptime" : "0 d, 0 h, 2 m, 31 s", 
    "git_hash" : "1ad73b298cd261861203fbffb9c789f6ade2796d", 
    "compile_time" : "Wed Feb 11 13:00:19 CET 2015", 
    "compiled_by" : "fermin", 
    "compiled_in" : "centollo" 
  } 
}

Firefox浏览器不喜欢这样的回复：

SyntaxError：JSON.parse：在JSON数据的第1行第14列的JSON数据之后出现意外的非空白字符

更好的JSON响应可能是：

{
  "statusCode" : {
    "code" : "200",
    "reasonPhrase" : "OK"
  }
}
