在jasper报告中显示Grails列表属性

grails jasper-reports

在jasper报告中显示Grails列表属性,grails,jasper-reports,grails-plugin,Grails,Jasper Reports,Grails Plugin,我不知道如何在jasper报告中呈现Grails中的列表属性 $F{divisions.[0].name} $F{divisions.[1].name} 我的域类如下所示： class Project { String name String division List divisions String toString(){ "$name" } static hasMany = [divisions : Division ] ... 这里是division域类 cla

我不知道如何在jasper报告中呈现Grails中的列表属性

 $F{divisions.[0].name}
 $F{divisions.[1].name}
我的域类如下所示：

class Project {


String name
String division
List divisions

String toString(){
    "$name"
}


static hasMany = [divisions : Division ]
...
这里是division域类

class Division {

String name
String divisionResponsible
String createDate

...
项目控制器如下所示

class ProjectController {


def scaffold = true

def index = {
    redirect(action : list)
}


def createReport = {

    def projectreport = Project.getAll([params.project_id])
    chain(controller:'jasper',action:'index',model:[data:projectreport],params:params)

}
}

我用iReport创建了一个jasper报告，效果很好。我在列表中添加了字段，它们通过访问例如$F{name}显示在报告中，但我不知道如何添加分区列表。我想要一个每行一个元素的列表

更新添加了jrxml文件：

现在的问题是，这在一个真实的报告中并不真正可用，因为我不知道列表中有多少元素

有没有一种方法可以遍历jasper报表中的列表元素？

您是否尝试过使用

<printWhenExpression><![CDATA[$F{data}.get(0) != null]]></printWhenExpression>
<textFieldExpression><![CDATA[$F{data}.get(0).name]]></textFieldExpression>
部门：

<printWhenExpression><![CDATA[$F{data}.get(0).divisions != null && $F{data}.get(0).divisions.get(0) != null]]></printWhenExpression>
<textFieldExpression><![CDATA[$F{data}.get(0).divisions.get(0).name]]></textFieldExpression>
你能发布jrxml文件吗？嗯，它实际上不起作用。如果我添加以下内容，我会得到一个错误：添加打印WhenExpression也不起作用。我必须准确地说出来吗？
