Remove extra blank space when no data in subreport

[bpamarti]

Hello:

 

I created a jasperreport with a subreport embedded beneath every row in the main report. Everything works fine but there is an extra white space beneath every row in the main report when there is no data in the subreport.

 

And also in other reports I noticed that there is extra space left unfilled in the detail section eventhough there is space to fit in couple of rows of data.

 

I am sure there has to be some setting to eliminate this whitespace ... can anyone shed some light on this...

 

I have set the isRemoveLineWhenBlank to "true" in the reportElement....below is the code snippet for the subreport in the jrxml file

 

 

Thanks a lot!
 

Code:

<subreport  isUsingCache="true">					<reportElement						x="0"						y="28"						width="760"						height="42"						key="subreport-3"						positionType="Float"						isRemoveLineWhenBlank="true"/>					<subreportParameter  name="pat_mrn">						<subreportParameterExpression><![CDATA[$F{pat_mrn}]]></subreportParameterExpression>					</subreportParameter>					<subreportParameter  name="sch_event_id">						<subreportParameterExpression><![CDATA[new Integer($F{sch_event_id})]]></subreportParameterExpression>					</subreportParameter>					<dataSourceExpression><![CDATA[new JRBeanCollectionDataSource($F{comments})]]></dataSourceExpression>					<subreportExpression  class="java.lang.String"><![CDATA[$P{SUBREPORT_DIR} + "waiting_comments_rpt.jasper"]]></subreportExpression>				</subreport>

Are there any other elements on the same line with the subreport (i.e. whose Y axis projection intersects the subreport's Y axis projection)?  In such cases, the subreport "line" would not be removed.
