Problem with org.docx4j.dml.chart.ObjectFactory

[trigeek]

So I am trying to reproduce the following XML as part of a test for chart addition:

</p:nvGraphicFramePr>
<p:xfrm>
<a:off x="1524000" y="1397000"/>
<a:ext cx="6096000" cy="4064000"/>
</p:xfrm>
<a:graphic>
<a:graphicData uri="http://schemas.openxmlformats.org/drawingml/2006/chart">
<c:chart xmlns:c="http://schemas.openxmlformats.org/drawingml/2006/chart" xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships" r:id="rId2"/>
</a:graphicData>
</a:graphic>
</p:graphicFrame>

And I get everything to work fine except creating the line:
<c:chart xmlns:c="http://schemas.openxmlformats.org/drawingml/2006/chart" xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships" r:id="rId2"/>

The code for this relevant portion is:

Graphic g = new Graphic();
GraphicData gd = new GraphicData();
gd.setUri("http://schemas.openxmlformats.org/drawingml/2006/chart");

org.docx4j.dml.chart.ObjectFactory factory = new org.docx4j.dml.chart.ObjectFactory();
CTRelId ctrelid = new CTRelId();
ctrelid.setId(relId);
JAXBElement<CTRelId> e = factory.createChart(ctrelid);

gd.getAny().add(e);
g.setGraphicData(gd);

What the above code produces (again in the relevant portion is):

<a:graphic>
<a:graphicData uri="http://schemas.openxmlformats.org/drawingml/2006/chart">
<c:chart r:id="rId2"/>
</a:graphicData>
</a:graphic>

As you can see the <c:chart is missing the xlmns:c and xmlns:r that is in the Powerpoint generated version....

What am i doing wrong?

Any help appreciated.

Thanks,
Rob

Those are namespace declarations, which you don't need to add explicitly, since JAXB takes care of that. You'll see it puts them on the root element.

After the graphic code lines, how do u add the graphic object to the main document file.
