I see this is old, but, for the next person looking for it...
我看到这是旧的，但是，对于下一个寻找它的人......
Jasper Studio and ireport sometimes creates empty descriptions for fields:
Jasper Studio 和 ireport 有时会为字段创建空描述：
<fieldDescription><![CDATA[]]></fieldDescription>
Delete these and you should stop getting this error.
删除这些，您应该停止收到此错误。

The answer of Yonatan works for me!!!, in fields
Yonatan 的答案对我有用！！！，在领域
<fieldDescription><![CDATA[]]></fieldDescription>
I change the attributo in JPA like this
我像这样更改 JPA 中的属性
<fieldDescription><![CDATA[someColumn]]></fieldDescription>
The someColumn is reffer a attribute that JPA Objecte contains, after change in desing report try the report and works. In java code, i build a List with only the object that print:
someColumn 是 JPA Objecte 包含的属性，在设计报告更改后尝试报告并工作。在java代码中，我构建了一个只有打印对象的列表：
List<Producto> toPrint = new Stack<>();
toPrint.add(selected);
JRBeanCollectionDataSource beanCollectionDataSource = new JRBeanCollectionDataSource(toPrint);
Works for me change the empty fields for attribute that JPA Object contains.
为我工作更改 JPA 对象包含的属性的空字段。

For me just passing falsefor the second parameter of JRBeanCollectionDataSource (isUseFieldDescription) solve my problem.
对我来说，只需传递falseJRBeanCollectionDataSource ( isUseFieldDescription)的第二个参数即可解决我的问题。
new JRBeanCollectionDataSource(collection, false);
回答by leocborges
This works for me.
这对我有用。
- Remove spaces if you added them in your report fields.
Add false like this.
JRDataSource JRdataSource = new JRBeanCollectionDataSource(/*your data's*/, false);
- 如果您在报告字段中添加了空格，请删除它们。
像这样添加false。
JRDataSource JRdataSource = new JRBeanCollectionDataSource(/*your data's*/, false);

Check your getter and setter. Improper naming might create a problem as in my case.
检查你的 getter 和 setter。在我的情况下，不正确的命名可能会产生问题。
