> During deserialization of the ArrayOfResponseMessagesType, the first thing it does is look for a qname of ArrayOfResponseMessagesTypeChoice, but what it finds is a qname of FindItemResponseMessage (one of the choice types). The qnames fail to match and so deserialization terminates.
> I don't understand why it's looking for a "XXXChoice" qname when that's an artificial type generated by Axis. The real type as specified in the WSDL is what is returned in the response, so it's no surprise it doesn't match. Any idea what's going on?
