| Deserialization failure when using abstract elements |
|
I'm currently coding a SOAP client to an interface defined by the WSDL below (namespaces changed to protect the guilty). I get the following error:
Error deserializing message: Cannot resolve searchZonesResponse/return/records/dnsName via MyTypema
+ps::dnswsImplService
The XML response looks like this:
<?xml version="1.0"?>
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
<S:Body>
<ns2:searchZonesResponse xmlns:ns2="http://dbdns.ws.example.com/" xmlns:ns3="http://ws.example.
+com">
<return>
<resultCode>100</resultCode>
<records xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="ns2:forwardRecordO
+bject">
<ttl>0</ttl>
<dnsName>www.example.com</dnsName>
<ipAddress>192.168.1.101</ipAddress>
</records>
</return>
</ns2:searchZonesResponse>
</S:Body>
</S:Envelope>
So, I get back a baseRecordObject sets the type to forwardRecordObject. Thus (in theory) since forw
+ardRecordObject inherits from baseRecordObject I should have the 'ttl' field from the baseRecordOb
+ject and all fields from the forwardRecordObject, the Typemaps lookup should do its thing, and all
+ should be well. Instead, the Typemaps hash has no values containing the forwardRecordObject class
+. I can make this work with some minor hackery to SOAP::WSDL::Expat::MessageParser and adding some
+ dummy entries to the MyTypemaps file, but I suspect that's not the correct solution. =) Is this
+something that wsdl2perl should be handling, or do I need to handle this on my end?
