<p>Hello,</p>
<p> </p>
<p>I have been battling with a relatively simple problem but for the life of me I cannot quite work out how to resolve it.</p>
<p> </p>
<p>I am just trying to create a very simple report with a sub report that displays 1 column based on the output from the master report. I am into day 2 of my BIRT experience so extremely new.</p>
<p> </p>
<p>I have been following this help guide</p>
<p> </p>
<p><a data-ipb='nomediaparse' href='
http://help.eclipse.org/kepler/index.jsp?topic=/org.eclipse.birt.doc/birt/sub-BuildingARptThatContainsSubreportsIntro.html'>http://help.eclipse.org/kepler/index.jsp?topic=/org.eclipse.birt.doc/birt/sub-BuildingARptThatContainsSubreportsIntro.html</a>and i am up to step 8. </p>
<p> </p>
<p>Everything up to that step worked exactly as expected.</p>
<p> </p>
<p>When I select the correct column in the Expression Builder and generate the report only the parent 'List' data is displayed. The child Table data is blank.</p>
<p> </p>
<p>The child data set query is</p>
<p> </p>
<p>select RSP_METER_HIST.METER_ID from RSP_METER_HIST</p>
<div>where RSP_METER_HIST.METER_NO = ?</div>
<div> </div>
<div>The parameter to be passed is a string. When I was testing it along the development stage I had a default value of "U1234567"</div>
<div> </div>
<div>Of course it showed the same child result for that default value exactly as the Help steps displayed.</div>
<div> </div>
<div>Why then when I move to the Expression builder 'Available Column Bindings -> LIST -> Meter No' selection does it not work?</div>
<div> </div>
<div>Any help would be appreciated. i have tried to append '"' + row["Meter No"] + '"'; and other such possibilities with no joy.</div>
<div> </div>
<div>Thanks,</div>
