表组件显示XML数据源的空白报告
Som*_*Som 7 xml jasper-reports
我在使用XML作为数据源在报表摘要面板中创建表组件时遇到问题,最终报表仅显示空白行.
下面是我的名为ProjectXML.xml的 xml数据源
<testsuites>
<testsuite name="testsuite1"/>
<testsuite name="testsuite2"/>
<testsuite name="testsuite3"/>
</testsuites>
下面是我的名为report12.jrxml的.jrxml文件

高级感谢您提供有关TestSuite名称的完整表格的任何帮助.
I've found a "hack" and not very nice method, but it is working.
You can add the main (report's) dataset and use it in the Table component.

In this sample I've used ((net.sf.jasperreports.engine.data.JRXmlDataSource)$P{REPORT_DATA_SOURCE}).dataSource("/testsuites/testsuite") expression for setting Table's datasource.
The result will be:
The another way to get design you want - is to use the Detail band (without using Table component).
I think the situation you described detects the bug of a JasperReports engine.
I've found similar posts at http://community.jaspersoft.com site: Table component and XML datasource and using table elements with xml datasource
