WSDLLiteralRegistry wrongly decodes empty string and nil to Mapping::Object

Description (Last modified by nahi)

Thanks to James. 

OK now I am fairly certain I have found a bug-  when the response
contains an empty string of type xsi:type="xs:string" it does not
return an empty string "" in the soap object.  See the PayerBusiness
and Street2 elements, and compare to above:

It seems that 'processContents="lax"' is not used to change the behaviour of wsdl4r : am I right ?

I see that <a href="http://dev.ctor.org/soap4r/ticket/189">Ticket
#189</a> is reported as fixed, but I just downloaded trunk from svn and
it deosnt appear to be doing the trick for empty strings.  Is it
because I dont have the nil="true" in the response?  I'm using php_soap
for the server end.

here's dump and mapped object...

I have the tarball dated 10-22-2006 and am also still having problems
with the CommissionJunction service. The empty UPC fields are returning
SOAP::Mapping::Objects.

I'm very sorry. I confused 'empty' with 'nil'. returning nil works now but empty string doesn't. I'll fix it.

05/03/07 01:01:02 changed by nahi

  • status changed from reopened to closed.
  • resolution set to fixed.

I was wrong.

According to getPartInfoResponse report, getting nil or empty object depends on the service definition. It can be a bug but I cannot look into it without more details. Please file a new ticket.

According to CommissionJunction? report, the result depends on the service that client use is rpc-encoded or doc-literal. (CommissionJunction? service seems to have both service). Please file a new ticket with more details.

Sorry for your confusion.
