jasperReport/iReport subreport shows blank (not displayed) - jasper-reports

Question

I am trying to create a sub report(report1_subreport3.jrxml) from the main report(report1.jrxml) using iReport designer (both with empty data source) . The main report detail band contains a static text ("Main Report") and the subreport element and the subreport contains a static text in its corresponding detail band("Sub Report")
But clicking the preview tab of the main report shows only static text "Main Report" not displaying the static text of subreport ("Sub Report") .
I also went through the link http://community.jaspersoft.com/questions/524978/empty-subreport-xml-datasource-ireport but still facing the issue .
Below is the report1.jrxml
<?xml version="1.0" encoding="UTF-8"?>

Answer 1

Place your sub-report field in the any other band other than detail band and add whenNoDataType="AllSectionsNoDetail" to your xml file. Add it among the other report properties in <JasperReport> tag. You can also add using the GUI Designer. Open your sub report and in the properties editor, at the end of the options you will find When No Data option. Select All Sections with No Detail from the list of available options.
Mainreport :
<?xml version="1.0" encoding="UTF-8"?>

This worked like a charm. Hope this helps.

Answer 2

Above issue got resolved using below tag which I had included in my mainreport. We need to use empty data source (new net.sf.jasperreports.engine.JREmptyDataSource())
SUBREPORT.jrxml
<?xml version="1.0" encoding="UTF-8"?>
<!-- Created with Jaspersoft Studio version 6.3.1.final using JasperReports Library version 6.3.1 -->
<!-- 2016-12-15T10:33:58 -->
<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="HYPERLINKS_SUBREPORT" pageWidth="595" pageHeight="842" columnWidth="595" leftMargin="0" rightMargin="0" topMargin="0" bottomMargin="0" uuid="ad9606b1-969d-4340-a7eb-61dc30ec8f0d">
<property name="com.jaspersoft.studio.data.defaultdataadapter" value="One Empty Record"/>

<property name="com.jaspersoft.studio.unit.leftMargin" value="pixel"/>
<property name="com.jaspersoft.studio.unit.rightMargin" value="pixel"/>
<property name="com.jaspersoft.studio.unit.columnWidth" value="pixel"/>
<property name="com.jaspersoft.studio.unit.columnSpacing" value="pixel"/>

XML of main_report.jrxml
<subreport>
<reportElement positionType="Float" x="0" y="220" width="200" height="60" uuid="62463158-73b1-4089-b66c-633d3a987649"/>
<dataSourceExpression><![CDATA[new net.sf.jasperreports.engine.JREmptyDataSource()]]></dataSourceExpression>
<subreportExpression><![CDATA["SUBREPORT.jasper"]]></subreportExpression>
</subreport>
The same can be achieved using Jaspersoft Studio.

Answer 3

Anyone having a problem with jasper reports studio 6.3.0 not displaying subreports should try changing the name of the parameter in the subreport and then update the parameter connection in the master reports subreport widget "edit parameter" option to match the new parameter name. Also might avoid underscore ie. "USER_ID".

Answer 4

In my case problem was caused by JasperReportStudio NOT building .jasper file after saving subreport. This caused the the main report to always include very first version of subreport I have created (which had some error, so was not displaying anything).
Solution is to press Ctrl-B after pressing Ctrl-S each time you save. This rebuilds subreport .jasper file and caused it to refresh properly in preview of main report.
