Any of those help I have three reports (main.rpt, sub1.rpt, sub2.rpt). In the main.rpt, in section 2, I have a empty subreport (without connection to the data). , Try:
code :
 r.Subreports("Your Sub report").SetDataSource(dset)

like below fixes the issue I'm using the iReport 4.5.1 and I've faced a problem with connecting master report and subreport. , Java Code:
code :
Map<String, Object> parameters = new HashMap<String, Object>();

//if you want this to be compiled in runtime

JasperReport jasperReport = JasperCompileManager.compileReport(your JRXMLReport path file here);
JasperReport subReport = JasperCompileManager.compileReport(your JRXMLSubReport path file here);

//you can notice that there're a lot of overloaded mathods to compile it, you can choose
//what is better in your case

//if you want to use the complied file *.jasper
JasperReport jasperReport = (JasperReport)JRLoader.loadObject(new File("filenameReport.jasper"));

JasperReport subReport = (JasperReport)JRLoader.loadObject(new File("filenameSubReport.jasper"));


//Then you add your subReport in your parameter Map
parameters.put("SUBREPORT_JASPER_FILE", subReport);

JasperFillManager.fillReport(jasperReport, parameters,
                new JRBeanCollectionDataSource(yourList));
<parameter name="SUBREPORT_JASPER_FILE" class="java.lang.Object"/> // you can also create this using the option in your iReport


<subreport>
    <reportElement uuid="c62c7896-f37a-4e76-a4cb-70e2545947da" style="Style" x="279" y="0" width="296" height="15"/>
       <dataSourceExpression>
            <![CDATA[new net.sf.jasperreports.engine.data.JRBeanCollectionDataSource($F{yourSubList})]]>  
       </dataSourceExpression>
            <subreportExpression><![CDATA[$P{SUBREPORT_JASPER_FILE}]]></subreportExpression>
</subreport>

will help you Generally speaking from what I have seen SSRS has THE WORST ERRORS KNOWN TO HUMANKIND on telling you what is wrong. Generally speaking I have seen this one and the main culprit is one of three things:
The Project needs to be rebuilt as you made changes to a subreport and the report data is not current. The Report data is corrupt some how and needs to be erased (look in your FILE location and delete the *.rdl.data file.) Your parameter you are passing in is bad or in the wrong format. All Subreports having parameters NEED TO HAVE THEM PASSED IN, or they will not run and give an error the equivalent of 'object set to an instance of a null'.

wish help you to fix your issue I think what you're describing sounds reasonable, though I'm not sure about the finer details. I'd recommend removing the setting of Link Master & Child in design view; it might also be a good idea to remove the subreports themselves from the sub-report controls on the parent reports. If you did this, when the report opens, the main report's open event will fire (because no child-reports yet exist):
code :
private sub report_open(cancel as integer)
    me.recordsource = ...
    me.childreport1.sourceobject = ... 'name of child report; 
        'this line will cause the open event of the sub report to fire; 
        'use that event to set the sub-report's record source by
        'if me.recordsource = "" then 
        '    me.recordsource = ... 
    me.childreport1.linkmasterfield = ... 'or whatever the property is called
    me.childreport1.linkchildfield = ...
end sub

With these it helps You need 2 details sections in your report. In 1 put the what ever you want to show when you have records. Right click the same section and select Section Expert.... Check the Suppress Blank Section checkbox so this space used by this section is suppressed when there is nothing to show. In the other details section add a formula that prints what you want to display when there are no records. In your example this would be "-". Create another formula for counting records and name it RecordCount.
