错误：“传递的参数.不是字符串类型。”

Question

我一直在努力克服这个错误，似乎找不到解决办法。我使用的是FW/1 - Framework 2.2，ACF 9，MS 2008，jQyery 1.10.2。我试图通过AJAX发布一个简单的表单，并得到这条错误消息。任何洞察力都是非常感谢的！

Detail:如果将组件名称指定为此参数的类型，则可能无法找到该组件的定义文件或无法访问。

消息：传递给setTaskLog函数的TASKLOG参数不是字符串类型的。

表单

<form id="taskActivityForm">    
   <input type="text" name="id" value="">
   <input type="text" id="taskID" name="taskID" value="">
   <div class="modal-body">
      <textarea name="taskLog" id="taskLog" class="input-block-level" rows="5"> </textarea>
   </div>
</form>

jQuery

​

​

$.ajax({
    type: "POST",
    url: "/ccc/tasklog/save",
    dataType: "json", 
    data: $("#taskActivityForm").serialize(),
    success: function(returnData){
      console.log(returnData);
    },
    error: function (jqXHR, textStatus, errorThrown) {
      console.log(textStatus);
      console.log(errorThrown);
    }
  });

服务tasklog.cfc

在get函数的新()调用之前，我做了一个cfdump。“测试”对我来说似乎是一根绳子。

提前感谢您的见解！

您正在用组件实例覆盖控制器中的rc.taskLog，该实例删除了从表单中提交的字符串。

 <cfset rc.tasklog = taskLogService.get(argumentCollection=rc) />

为组件实例选择与窗体字段不同的变量名。
