Handling Nillable elements which are wsdl choices

[Dushshantha Chandradasa]

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??   Regards,   Marcus Dushshantha Chandradasa Associate  Software Engineer Virtusa (Pvt) Ltd.
