221505 - Can't find a decoder for a simple complexType

Status: RESOLVED FIXED

(Core Graveyard :: Web Services, defect)

WSDL: http://nexgenmedia.net/evang/wsdom.wsdl

Am calling getCommand():

in wspcallcontext.cpp, line 353:

      nsCOMPtr<nsIVariant> value;
      rv = block->GetValue(getter_AddRefs(value));
      if (NS_FAILED(rv) || !value) {
        goto call_completion_end;
      }

value is empty, so we quit.  GetValue seems to fail due to not finding a decoder
(nsSOAPEncoding::Decode).

I tried debugging it afurthur, seems in nsdefaultsoapencoder.cpp, line 2016, we
have a for(;;) loop looking for a decoder.  It finds the DOMCommand one, but
continues too go up the chain (so for some reason it thinks the DOMCommand
decoder is not the one it wants) and finds AnyType, then I stopped debugging it.

nssoapencoding.cpp 
nsSOAPEncoding:GetDecoder

seems to walk a hash of decoders, and doesn't seem to find any for
urn:WSDOM#DOMCommand.

jst: do you by chance know where we process the wsdl file and create the
decoders and encoders for the complex types in the file?  I can't seem to find
that place.

tried to debug an working complexType example (amazon), and it seems to get the
AnyType decoder. So "decoder" is a ptr to an nsAnyTypeEncoder.

Not sure why its not doing this for the apache axis one.
