Hi,
I want to consume a Web Service that returns a choice, but my C++ client
always receives the same returned type. On the other hand, when I am using a
Java client, it is working fine (of course, the generated proxy is not the
same).
When I am looking at the C++ generated code, it seems fine, but when I am
executing the code, I always get the first choice type.
Do someone already used a returned choice in C++ ?
(I am using Visual Studio 2003).
Here is the execute code:
// -------------------------
// My test code
// -------------------------
Object *queryResult = webService->queryMatchingPersonsByTraits(
fillRequestType(condition), szProductID, Convert::ToString(iMaxReturnRow),
totalNumberOfMatches, timestamp );
Query::PersonQueryResponseTypeMatchingProfiles *profiles =
dynamic_cast<Query:: PersonQueryResponseTypeMatchingProfiles *>(queryResult);
if ( profiles == NULL )
{
Query::PersonQueryResponseTypeError* error =
dynamic_cast<Query::PersonQueryResponseTypeError*> (queryResult);
String *value = error->Value;
}
//I never receive a PersonQueryResponseTypeMatchingProfiles in my C++ code,
but I am receiving some in the Java code.
