如何使用JavaScript在CRM 2011中创建自定义活动？

Question

我已经试过这样：

function CreateCustomActivity(oDataPath, oDataSetName, subject, entityId, entityTypeCode) {  
    var customactivity = new Object(); 
    customactivity.subject = subject; 
    customactivity.regardingobjectid = entityId; 
    customactivity.activitytypecode = entityTypeCode; 

    var jsonCustomActivity = JSON.stringify(customactivity); 

    var req = new XMLHttpRequest(); 
    req.open("POST", oDataPath + "/" + oDataSetName, false); 
    req.setRequestHeader("Accept", "application/json"); 
    req.setRequestHeader("Content-Type", "application/json; charset=utf-8"); 
    req.send(jsonCustomActivity); 
} 

不过，我得到以下错误：

Error processing request stream. The property name 'subject' specified for type 'Microsoft.Crm.Sdk.Data.Services.new_customactivity' is not valid.

我添加到customactivity对象的第一属性是在错误消息中引用。当我首先添加regardingobjectid时，我会得到相同的消息。

尝试使用下面的符号创建活动对象：

var customactivity = { 
    Subject: subject, 
    RegardingObjectId: { 
     Id: entityId, 
     LogicalName: entityLogicalName 
    }   
}; 

而且，我不知道了手，但物业的名称可能是区分大小写的。
