Description

I have the following snippet of code and i get a very strange
Exception(possibly a bug, it doesn't make any other sense).

sample code:

public OMElement webServiceMethod1(OMElement payload){
//parse incoming OMElement-> successfully done..
//Create the XML Model:
OMFactory fac = OMAbstractFactory.getOMFactory();
OMNamespace omNs =fac.createOMNamespace("http://authentication.liferay.services.acer.com","xsd");
OMElement method = fac.createOMElement("authentication_response", omNs);
//succeed
OMElement value1 = fac.createOMElement("succeed", null);
value1.addChild(fac.createOMText(value1, isSuccessful ));
//authentication_response<- (succeed)
method.addChild(value1);

//CRITICAL PART: i try to print all "<method>"'s data: Trying to System.out the OMElement
way1:
String response = result.getFirstElement().getText();
System.out.println("response= "+response);

And i get: " Exception in thread "main" org.apache.axiom.om.OMException:
java.lang.ClassCastException: org.apache.axiom.om.impl.llom.OMElementImpl "
but it doesn't make sense, cause OMElement is of type: OMElementImpl!

way2:
OMFactory fac2 = OMAbstractFactory.getOMFactory();
StAXOMBuilder builder=new StAXOMBuilder(fac2,method.getXMLStreamReader(),method);
OMElement documentElement=builder.getDocumentElement();
try

{ System.out.println("xml= "+documentElement.toStringWithConsume()); }

catch (XMLStreamException e)

{ e.printStackTrace(); }

And i get:
"Exception in thread "main" java.lang.IllegalStateException: attribute count
accessed in illegal event (7)!

But it doesn't make sense again!
