Exception from Serializer.fromXml()

Hi,

I am trying to create a org.eclipse.birt.chart.model.Chart object from an xml file using Serializer.fromXml()

My code for reading is: (ignoring Exceptions)
org.eclipse.birt.chart.model.Chart chartFromFile(File xmlFile)
{
FileInputStream fis = new FileInputStream(xmlFile);
int nBytes = (int)(xmlFile.length()); //(The file length fits into an int)
byte[] buf = new byte[nBytes+1];
int nRead = fis.read(buf);
ByteArrayInputStream baStream = new ByteArrayInputStream(buf);
Serializer ser = SerializerImpl.instance();
// The next line throws an Exception
org.eclipse.birt.chart.model.Chart birtChart = ser.fromXml(baiStream, true); //(I tried true and false)
fis.close();
return birtChart;
}

I always get the following Exception:

org.eclipse.emf.ecore.resource.Resource$IOWrappedException: Content is not allowed in trailing section.

(I am running in IBM RAD 7.0 - Eclipse-based)

My xml files have an <model:ChartWithAxes> element as the outermost element.
I have tried generating the xml in two ways:

1) I created an .rptdesign file in the BIRT designer (2.3.0). I then extracted the chart from the file and saved it as an xml.
2) I use the API to create a org.eclipse.birt.chart.model.Chart object and then used Serializer.asXml() to create an xml file:

private void writeXml(Chart chart)
{
Serializer s = SerializerImpl.instance();
ByteArrayOutputStream st = s.asXml(chart, true);
String xml = st.toString();
PrintWriter pw = new PrintWriter(new FileWriter("c:/BIRT/Reports/test.xml"));
pw.println(xml);
pw.close();

}

Either way, I throw an Exception when I try to read the xml.
(BTW, I am able to parse the xml file using javax.xml.parsers.DocumentBuilder)

Does anyone know what I am doing wrong?

Thanks,
