razorflow使用过程中提示RFComponent不存在

[Christopher_Lv]

使用razorflow时提示如下错误
Fatal error: Class 'RFComponent' not found in TableComponent.php on line 9
TableComponent是razorflow里自带的文件，怎么也报错了？有人遇到过吗
如下会调用TableComponent.php

<?php
require_once("razorflow_php\lib\core\StandaloneDashboard.php");
require_once("razorflow_php\lib\components\TableComponent.php");
class SampleDashboard extends StandaloneDashboard {
    public function buildDashboard () {
        $table = new TableComponent('table1');
        $table->setCaption("Regional Sales");
        $table->setDimensions (4, 4);
        $table->setRowsPerPage (8);
        $table->addColumn('zone', "Zone");
        $table->addColumn('name', "Store Name");
        $table->addColumn('sale', "Sales Amount", array(
          "dataType" => "number",
          "numberPrefix" => "$ ",
          "textAlign" => "center"
        ));

        $data = array(
          array("zone" => "North", "name" => "Northern Stores", "sale" => 4000),
          array("zone" => "South", "name" => "Southern Stores", "sale" => 4500)
        );

        $table->addMultipleRows($data);

        $this->addComponent ($table);
    }
}

$db = new SampleDashboard();
$db->renderStandalone();

找到解决方法了，不用requreonce（）里面的类库，所有的都会引入了
