In your generic element handler, add JRPdfExporterContext.getOffsetX()/Y
to the position of the element, that is use element.getX() + exporterContext.getOffsetX()
everywhere instead of element.getX()
.
JasperReports/PDF: issue for positioning generic element included in a list component

Question
I'm working on a PDF in which I'm trying to have a checkbox in front of each line of a "list" JR component.
I already have some editable fields (text and radio) in my report, in the 'Title' section; everything goes well.
To do that, I use "generic elements" and have some handlers written in Java who generate for example iText TextField in a rectangle (com.lowagie.text.Rectangle.Rectangle), defined like this ('element' is the current generic element, of type JRGenericPrintElement):
element.getX(),
exporterContext.getExportedReport().getPageHeight() - element.getY(),
element.getX() + element.getWidth(),
exporterContext.getExportedReport().getPageHeight() - element.getY() - element.getHeight()
The 'generic element' is defined like this in my .jrxml :
<genericElement>
<reportElement uuid="ec205c41-afe2-44fd-a8b3-03e2d4b07ce6" x="72" y="132" width="143" height="25"/>
<genericElementType namespace="http://namespace" name="simpleEditableTf"/>
<genericElementParameter name="name">
<valueExpression><![CDATA["matricule"]]></valueExpression>
</genericElementParameter>
</genericElement>
I would like to use the same code to define the position of my list checkboxes, but it seems that in the case the generic element is used into a list, the element.getX() and element.getY() methods return the coordinates relatively to the list component.
So rather to have the coordinates of the element in the page (eg. X=50,Y=200) I have these relative to the list component itself (X=4,Y=7); so it's impossible to set the element correctly.
Here is the code of the list element, including the generic element.
<componentElement>
<reportElement uuid="0aa17cac-d5e2-4592-ba0d-ab8e25cc989b" x="10" y="10" width="476" height="23" forecolor="#366798"/>
<jr:list xmlns:jr="http://jasperreports.sourceforge.net/jasperreports/components" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports/components http://jasperreports.sourceforge.net/xsd/components.xsd" printOrder="Vertical">
<datasetRun subDataset="item_ab" uuid="3c25ec33-3a70-497f-b234-0d5ea64cabcf">
<dataSourceExpression><![CDATA[$P{REPORT_DATA_SOURCE}.subDataSource("//item_ab")]]></dataSourceExpression>
</datasetRun>
<jr:listContents height="23" width="476">
<textField isStretchWithOverflow="true">
<reportElement uuid="0158660b-3ab1-4149-8599-77824c64082f" x="20" y="1" width="420" height="20"/>
<textElement verticalAlignment="Middle"/>
<textFieldExpression><![CDATA[$F{libelle_ab}]]></textFieldExpression>
</textField>
<genericElement>
<reportElement uuid="12c64be4-27dd-4aa2-8d50-f412e25d9805" x="4" y="7" width="9" height="9"/>
<genericElementType namespace="http://namespace" name="checkBox"/>
</genericElement>
</jr:listContents>
</jr:list>
</componentElement>
Could someone tell me if I did something wrong? Is it a bug?
