从 Flex (Salesforce) 创建自定义字段

Question

我正在尝试从 Flex 创建自定义字段，但我很难找到正确的语法。

下面是我正在使用的代码片段，它导致错误“sf:INVALID_TYPE INVALID_TYPE:创建/更新请求中不允许空对象”

    var con:Connection = new Connection();
    var lRequest:LoginRequest = new LoginRequest();
    lRequest.username = username1.text;
    lRequest.password = password1.text;
    lRequest.callback = new mx.rpc.Responder(createFields, loginFault);
    con.login(lRequest);

    //CreateFields Method ....
    var externalIdField:CustomField = new CustomField();
    externalIdField.label = 'ProductionId';
    externalIdField.type = FieldType.ID;
    externalIdField._length = 18;
    externalIdField.externalId = true;
    externalIdField.unique = true;

    var customObjectVar:CustomObject = new CustomObject();
    customObjectVar["type"] = "Account";
    customObjectVar.addField(externalIdField);

    var objarray:Array = [];
    objarray[0]=customObjectVar;
    con.updateObject(objarray,new mx.rpc.Responder(saveresults,sfdcFailure));

尝试了以下替代方法（按照西蒙的建议），这也会导致错误

“soapenv：客户端元素 {http://soap.sforce.com/2006/04/metadata}类型 在此位置无效”

    var externalIdField:CustomField = new CustomField();
    externalIdField.fullName = 'Account.ProductionId__c';
    externalIdField.type = FieldType.STRING;
    externalIdField._length = 18;
    externalIdField.externalId = true;
    externalIdField.unique = true;

    var objarray:Array = [];
    objarray[0]=externalIdField;
    con.updateObject(objarray,new mx.rpc.Responder(saveresults,sfdcFailure));

要创建字段，您需要将 CustomField 实例传递给元数据 api create 调用（从您的代码中不清楚 con 是什么），除了您设置的字段之外，您还需要设置 fullName （例如本例中的 Account.ProductionId__c ）
