Eran Chinthaka commented on WSCOMMONS-10: ----------------------------------------- I can give this a try. But I prefer if we can wait till 1.0. Axiom was hanging around for some time and proven to be stable. So lets release the stable version as 1.0 and do these changes. FYI : The correct solution for this is to implement the NamespaceContext in our parser wrapper. So shall we agree to fix this for 1.1 and wait for 1.0, please ? -- Chinthaka > Request to have a utility method to get a copy of child OMElement whose > namespaces may be declared at parent OMElements > ----------------------------------------------------------------------------------------------------------------------- > > Key: WSCOMMONS-10 > URL: http://issues.apache.org/jira/browse/WSCOMMONS-10 > Project: WS-Commons > Type: Improvement > Components: AXIOM > Reporter: Raymond Feng > > Here's the topic we discussed at Axis2 mailing list. > Raymond Feng wrote: > > Hi, > > > > I have an OM containment hiearchy as "SOAPEnvelope --> SOAPBody --> > > OMElement e1" and the namespace xmlns:ns1="http://ns1"; is declared at > > the SOAPEnvelope level (I observe that It's the behavior when the > > SOAPEnvelope is received from the Axis2 engine). > > > > XMLStream reader = e1.getXMLStreamReader(); > > > > For the reader, I found "reader.getNamespaceCount()" returns 0.
