coldfusion - cfgrid format=flash 不显示结果

Question

我正在尝试使用带有 format=flash 的 cfgrid 标记来显示查询结果。它不显示输出而是生成网格。我尝试的示例代码是：

<cfquery name = "GetCourses" dataSource = "cfdocexamples"> 
    SELECT Course_ID, Dept_ID, CorNumber, 
    CorName, CorLevel 
    FROM CourseList 
    ORDER by Dept_ID ASC, CorNumber ASC 
</cfquery> 

<h3>cfgrid Example</h3> 
<i>Currently available courses</i> 
<!--- cfgrid must be inside a cfform tag. ---> 
<cfform> 
 <cfgrid name = "FirstGrid" format="flash"  
    height="320" width="580" 
    font="Tahoma" fontsize="12" 
    query = "GetCourses"> 
 </cfgrid> 
</cfform>
