The problem seems to come from this method (In AxiomHelper) :
public static DataObject toDataObject(TypeHelper typeHelper,
Object[] os, QName typeQN) {
XSDHelper xsdHelper = new XSDHelperImpl(typeHelper);
Property property =
xsdHelper.getGlobalProperty(typeQN.getNamespaceURI(),
typeQN.getLocalPart(),
true);
System.out.println( "TypeQN : " + typeQN.toString() ); // <---
Added for degug
DataObject dataObject = new
DataFactoryImpl(typeHelper).create(property.getType());
List ips = dataObject.getInstanceProperties();
for (int i = 0; i < ips.size(); i++) {
dataObject.set(i, os[i]);
}
return dataObject;
}
The exception is thrown because property is null.
xsdHelper.getGlobalProperty return null when trying to get
"getGreetings" QName.
I don't really understand where does the problem come from ...
Are you aware of that problem ?
I checkout SVN release 397143, running mvn, configuring my Eclipse
environment according
to your wiki installation page.
Hi, I think this should be fixed by my fix to JIRA issue TUSCANY-237 /
revision r397472. Could you please do an svn up and try again? Thanks.
