Jasper SubReport doesnt' show in Master - jasper-reports

Question

I asked a similar question a year ago and didn't discover a resolution. The subreport I am working on now is in the detail band of the master, although I did try it in others just in case.
<detail>
<band height="34" splitType="Stretch">
<subreport>
<reportElement stretchType="RelativeToTallestObject" isPrintRepeatedValues="false" mode="Transparent" x="0" y="0" width="555" height="34" uuid="6318f4b9-c420-4294-a63f-1a83d338f755">
<property name="local_mesure_unitheight" value="pixel"/>
<property name="com.jaspersoft.studio.unit.height" value="px"/>
</reportElement>
<subreportParameter name="item_id">
<subreportParameterExpression><![CDATA[$F{item_id}]]></subreportParameterExpression>
</subreportParameter>
<connectionExpression><![CDATA[$P{REPORT_CONNECTION}]]></connectionExpression>
<subreportExpression><![CDATA["report.jasper"]]></subreportExpression>
</subreport>
</band>
</detail>
I checked the path to the subreport is correct. In the subreport the parameter_name is exactly the same. The .jasper file is compiled successfully.
The master report has a call to a stored procedure, and I am using one of the fields it is returning as the subreport parameter. I called it 'item_id' here. I used the wizard to map that to the subreport parameter with the same name. The idea is that the subreport should return additional information about each of the item_ids returned by the SP in the master report.
When I run the subreport on it's own it returns data for a particular item_id. I created a variable in the master to track how many rows the SP itself returns and when I run the master it shows the correct number of rows exist but no data displays on the master report. It also leaves enough empty space to appear to indicate that something is being returned but just not displayed. When I set 'remove line when blank' for the subreport element in properties from the master report I get no rows - so apparently it is returning a blank line 44 times - one for each row. Or is it?
One suggestion was to remove the connection_expression and replace it with parameters_map_expression but that didn't help either.
My best guess is that the subreport data is not getting to the master for some reason. If anyone has any suggestions I am open to anything I can do with JasperSoftStudio 6.3.

I changed some of the names of things for proprietary reasons. Hopefully they are consistent. If something doesn't jive it was probably lost in translation.
As noted the query works fine in the subreport. When i give it one of the item_ids from the procedure in the master report it displays all the fields correctly for that item. It just won't come through to the master report.

Answer 1

You could try to print the subreport parameter $P{item_id} in the title band of the subreport to check if the parameter passing works correctly.
Depending on the height of the main reports detail band, Maybe you have to remove the top and bottom margin of the subreport.
