Handling Nillable elements which are wsdl choices

[Dushshantha Chandradasa <dc...@virtusa.com>]

Hi All,

 

I implemented the support for 'choice' WSDL construct in Axis C++ .
According to our design,  generated stub level classes serialize the
choice elements in the following way.

 

int Axis_Serialize_ChoiceComplexType(ChoiceComplexType* param,
IWrapperSoapSerializer* pSZ, bool bArray = false)

{

            if ( param == NULL )

            {

             /* TODO : may need to check nillable value - Now done*/

                        pSZ->serializeAsAttribute( "xsi:nil", 0,
(void*)&(xsd_boolean_true), XSD_BOOLEAN);

                        pSZ->serialize( ">", NULL);

                        return AXIS_SUCCESS;

            }

 

            /* first serialize attributes if any*/

            pSZ->serialize( ">", 0);

 

            /* then serialize elements if any*/

            pSZ->serializeAsElement("NonChoiceIntValue",
Axis_URI_ChoiceComplexType, (void*)&(param->NonChoiceIntValue),
XSD_INT);

            

//......................................................................
..............................................................

//Following two elements are choice elements

// if the element is not NULL it goes to deserializer

 

if(param->IntValue)

            {

                        pSZ->serializeAsElement("IntValue",
Axis_URI_ChoiceComplexType, (void*)(param->IntValue), XSD_INT);

            }

            else if(param->StringValue)

            {

                        pSZ->serializeAsElement("StringValue",
Axis_URI_ChoiceComplexType, (void*)(param->StringValue), XSD_STRING);

            }

            

//......................................................................
..................................................................

pSZ->serializeAsElement("NonChoiceStringValue",
Axis_URI_ChoiceComplexType, (void*)(param->NonChoiceStringValue),
XSD_STRING);

            return AXIS_SUCCESS;

}

 

 

But if the choice element is a nillable one and its value is set to
NULL, then the above logic will fail. 

 

Any thoughts on this??
