[GoogleCodeExporter]

What steps will reproduce the problem?
1.try create a entity which have a property and the property type is complex 
type

What is the expected output? What do you see instead?
create correctly, can not generate XML

What version of the product are you using? On what operating system?
0.4

Please provide any additional information below.

I think the method 
org.odata4j.format.xml.XmlFormatWriter.writeProperty(XMLWriter2 writer, 
OProperty<?> prop, boolean isDocumentElement)
have some logic problem, if the prop is complex type, then at the end of this 
method, value!=null and sValue == null which will cause NullPointerException
