AXIS2 ADB base64binary problem

I look today into problem “Unexpected element”. Developer use a code generation utility wsdl2java for AXIS2. Everything working fine except attachments. Service call fail with exception “Unexpected element attachment”.  I found that element attachment is successfully start to processing, but fail to finished. The problem in the code:

	if (reader.isStartElement() && new javax.xml.namespace.QName("http://company.com/service/model/v1", "attachment").equals(reader.getName()))
	{
		reader.next();
		if (isReaderMTOMAware(reader) && java.lang.Boolean.TRUE.equals(reader.getProperty(org.apache.axiom.om.OMConstants.IS_BINARY)))
		{
			//MTOM aware reader - get the datahandler directly and put it in the object
			object.setAttachment((javax.activation.DataHandler) reader.getProperty(org.apache.axiom.om.OMConstants.DATA_HANDLER));
		}
		else
		{
			if ((reader.getEventType() == javax.xml.stream.XMLStreamConstants.START_ELEMENT) && reader.getName()
				.equals( new javax.xml.namespace.QName(org.apache.axiom.om.impl.MTOMConstants.XOP_NAMESPACE_URI,
						org.apache.axiom.om.impl.MTOMConstants.XOP_INCLUDE)))
			{
				final java.lang.String id = org.apache.axiom.om.util.ElementHelper.getContentID(reader, "UTF-8");
				object.setAttachment(((org.apache.axiom.soap.impl.builder.MTOMStAXSOAPModelBuilder) ((org.apache.axiom.om.impl.llom.OMStAXWrapper) reader).getBuilder()).getDataHandler(id));
				reader.next();

				reader.next();

			}
			else if (reader.hasText())
			{
                               String content = reader.getText();
				object.setAttachment(org.apache.axis2.databinding.utils.ConverterUtil.convertToBase64Binary(content));
			}
		}
		reader.next();
	} // End of if for expected property start element

We don’t use MTOM, so problem was in section

else if (reader.hasText()){

Looking into reader data I found that content of element “attachment” contains multiple text nodes, but expected only one node. It seams that parser reads base64binary not in one piece, but multiple chunks.
So instead I use next code:

  else if (reader.hasText()) {
            String content = "";
            while(reader.hasText()){
                content+=reader.getText();
                reader.next();
            }
         object.setAttachment(org.apache.axis2.databinding.utils.ConverterUtil.convertToBase64Binary(content));
   }

Now all working as expected.

    Hi,
    I use 1.4.1 also. Please, check if you apply fix in right place of code. You could use debugger to check is fix working.
