Subject: SOAP4R and ur-types

Hello,

I am trying to implement a SOAP client in Ruby 1.8.1 that queries a
service and gets a response. I've followed NaHi's examples, and have
had some success until I query the service and the response is an
array of ur-types. Then, my program crashes horribly.

Below is the response off the wire. All names of SOAP methods and
stuff have been changed and/or mangled to protect the innocent (CYA on
my NDA, natch):

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope
SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/1999/XMLSchema">
  <SOAP-ENV:Body>
    <m:GetThingiesResponse xmlns:m="FooAPI">
      <count xsi:type="xsd:int">2</count>
      <Thingies SOAP-ENC:arrayType="xsd:ur-type[2]" xsi:type="SOAP-ENC:Array">
        <Thingy>
          <id xsi:type="xsd:int">111111</id>
          <name xsi:type="xsd:string">Thing #1</name>
        </Thingy>
        <Thingy>
          <id xsi:type="xsd:int">111112</id>
          <name xsi:type="xsd:string">Thing #2</name>
        </Thingy>
      </Thingies>
    </m:GetThingiesResponse>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Here's the code:

require 'soap/rpc/driver'

server    = "http://someplace.com/soap"
namespace = "FooAPI"
wiredump  = STDERR

drv = SOAP::RPC::Driver.new( server, namespace )
drv.wiredump_dev = wiredump
drv.add_method( "GetThingies", "arg1", "arg2" )

p drv.GetThingies( 0, 1 )

And here is the stack trace I'm getting: 

/usr/local/lib/ruby/1.8/soap/mapping/mapping.rb:157:in

        from (eval):2:in `GetThingies'
        from thingy_test.rb:11


Any ideas? Is this where I roll up my sleeves and use the mapping
registry? And, if so, how? (And yes, I've read this already:

Thanks,
