Hi Randy and Monks:

Thanks for the helpful info! I have got the order sorted out but am having trouble with the namespaces. I reread your article a few times but I must be missing something.

My old requests had:

    ...<arrayOfEventModel_1 
        xsi:type="SOAP-ENC:ArrayOfEventModel" 
        SOAP-ENC:arrayType="namesp1:EventModel[1]">
                
        <item xsi:type="namesp1:EventModel">...

and this was OK. But, the new requests have:

    ...<arrayOfEventModel_1 
        xsi:type="SOAP-ENC:ArrayOfEventModel" 
        SOAP-ENC:arrayType="xsd:ur-type[1]">
                
        <item>...
[download]

I have noted that $attr (as received by serialize_complex_type) is a zero length string. I assume this impairs the intended namespace handling.

My plan after this was to review the SOAP::Serialzer package AUTOLOAD sub (assuming it handles the as_whatever__class calls) and reuse some of this code in the serialize_complex_type sub in attempts to preserve the way this part of the serialization is handled. But there is no AUTOLOAD!

Please let me know how I can locate this code, or if there's another angle to try.

Thanks in advance,
Rob
