在 jasperreports 3.5.3 中找不到字段

Question

我在 iReport Designer 中向我的报表添加了一个数据源，然后我将一些 "Text Field" 从报表元素面板拖到详细信息区域，我在编译 jasper 报表时遇到错误：

   net.sf.jasperreports.engine.design.JRValidationException: Report design not valid : 
          [jrc]      1. Field not found : deviceCostsDTO

甚至声明了字段：

<field name="deviceCostsDTO" class="com.domain.device.DeviceCostsDTO">
        <fieldDescription><![CDATA[actionCostsDTO]]></fieldDescription>
    </field>

并在此处使用：

 <frame>
                    <reportElement positionType="Float" x="0" y="155" width="802" height="60" isRemoveLineWhenBlank="true" />
                    <componentElement>
                        <reportElement x="0" y="36" width="802" height="24" isRemoveLineWhenBlank="true" />

您正在列表中使用此字段。您应该声明为列表正在使用的数据集的字段。

像这样：

<?xml version="1.0" encoding="UTF-8"?>
<jasperReport xmlns="http://jasperreports.sourceforge.net/jasperreports" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports http://jasperreports.sourceforge.net/xsd/jasperreport.xsd" name="report1" language="groovy" pageWidth="842" pageHeight="595" orientation="Landscape" columnWidth="802" leftMargin="20" rightMargin="20" topMargin="20" bottomMargin="20">
<property name="ireport.zoom" value="1.0"/>
<property name="ireport.x" value="0"/>
<property name="ireport.y" value="0"/>
<subDataset name="testDataset">
    <field name="testField" class="java.lang.String"/>
</subDataset>

    <band splitType="Stretch"/>

                <jr:listContents height="20" width="791">
                    <textField>

                        <textElement/>
