Description

Hello there,

we are using AXIS2 to generate and use ServiceStubs to handle SOAP webservices.
We upgraded AXIS2 from 1.6.4 to 1.7.6.
After that we generated a new ServiceStub via WSDL2Java based on the following command:

wsdl2java -uri xtc_wsdl.xml -s -d adb -u -S ./

(xtc_wsdl.xml is attached)

If we now get the following response from the webservice, the parsing runs into a IllegalStateException.

getOrdersByStatus_response.xml:

<?xml version="1.0" encoding="utf-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="webservice/xtc/plugins/Speed4Trade/com">
	<SOAP-ENV:Body>
		<ns1:getOrdersByStatusResponse>
			<orders/>
		</ns1:getOrdersByStatusResponse>
	</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Error:
java.lang.IllegalStateException: attribute type accessed in illegal event!

I have debugged the Stub and compared it to the old one of version 1.6.4.
I noticed here a code change caused by a change in the XSL template https://github.com/apache/axis2-java/commit/26d78d25e60183c14d901139ad3cdce432e393d0:

ADBBeanTemplate-bean.xsl, line 2190

This generates now this statement in the Orders.java:

                if ((reader.isStartElement() &&
                        new javax.xml.namespace.QName("", "orders").equals(
                            reader.getName())) ||
                        new javax.xml.namespace.QName("", "orders").equals(
                            reader.getName())) {...}

Is it possible that this if-statement is not correct?

Thanks for considering my request.
