Duplicate detail row

fro

<p>Hello,</p>
<p> </p>
<p>I design a report for printing item label.</p>
<p> </p>
<p>I would like to duplicate each detail row with a report parameter that define how many time each Item repeating.</p>
<p> </p>
<p>Example :</p>
<p> </p>
<p>Value of report parameter (Qty of label by item) : 3</p>
<p> </p>
<p>-label_item1</p>
<p>-label_item1</p>
<p>-label_item1</p>
<p>-label_item2</p>
<p>-label_item2</p>
<p>-label_item2</p>
<p>-label_item3</p>
<p>-label_item3</p>
<p>-label_item3</p>
<p> </p>
<p>How can i achieve this ?</p>
<p> </p>
<p>Thanks.</p>

<p><a data-ipb='nomediaparse' href='http://developer.actuate.com/community/forum/index.php?/user/49613-matthew-l/'>Matthew</a&gt; and I discussed this.  You can get a handle to the detail row of the table in the beforeFactory and clone it (copy a row, insert a row, and paste a row).</p>
<p> </p>
<p>Here's how you would clone a single row (for example):</p>
<pre class="_prettyXprint">
importPackage( Packages.org.eclipse.birt.report.model.api );

table = reportContext.getReportRunnable().designHandle.getDesignHandle().findElement("myTable");

elementFactory = reportContext.getReportRunnable().designHandle.getElementFactory();

tableHeaderRow            = new RowOperationParameters(0, -1, 0);    // Header row  (First arg: 0 is the HEADER, 2 is DETAIL, 3 is FOOTER, Second arg is group, Third arg is slot number)
tableDetailSource         = new RowOperationParameters(2, -1, 0);    // Detail row  (Slot is 0)
tableDetailDestination    = new RowOperationParameters(2, -1, 1);    // Detail row NEW  (New Slot so it's 1);

rowSource = table.copyRow( tableDetailSource );
table.insertRow( tableDetailDestination );
table.pasteRow( rowSource, tableDetailDestination );</pre>
<p>Here's how you would clone the source row multiple times:</p>
<pre class="_prettyXprint">
importPackage( Packages.org.eclipse.birt.report.model.api );

table = reportContext.getReportRunnable().designHandle.getDesignHandle().findElement("myTable");

elementFactory = reportContext.getReportRunnable().designHandle.getElementFactory();

for(var i=1; i<params["NumberOfTimes"].value; i++){
    rowSource = table.copyRow( new RowOperationParameters(2, -1, (i-1)) );
    table.insertRow( new RowOperationParameters(2, -1, i) );
    table.pasteRow( rowSource, new RowOperationParameters(2, -1, i) );
}</pre>
