I ran across and interesting quirk when I upgraded to 1.5
Element e = DocumentHelper.createElement("test");
e.add(DocumentHelper.createElement("another").addCDATA(null));
System.out.println(e.asXML());
System.out.println(DocumentHelper.createDocument(e).asXML());
The first System.out line renders <test><another><![CDATA[null]]></another></test>
While the next line System.out will throw a NullPointException.
java.lang.NullPointerException at java.io.Writer.write(Writer.java:126) at org.dom4j.io.XMLWriter.writeCDATA(XMLWriter.java:957) at org.dom4j.io.XMLWriter.writeNode(XMLWriter.java:1089) at org.dom4j.io.XMLWriter.writeElementContent(XMLWriter.java:945) at org.dom4j.io.XMLWriter.writeElement(XMLWriter.java:819) at org.dom4j.io.XMLWriter.writeNode(XMLWriter.java:1079) at org.dom4j.io.XMLWriter.writeElementContent(XMLWriter.java:945) at org.dom4j.io.XMLWriter.writeElement(XMLWriter.java:825) at org.dom4j.io.XMLWriter.writeNode(XMLWriter.java:1079) at org.dom4j.io.XMLWriter.write(XMLWriter.java:293) at org.dom4j.tree.AbstractDocument.asXML(AbstractDocument.java:71) at SimpleTest.main(SimpleTest.java:192) Exception in thread "main"
