[RESOLVED] Cannot deserialize successfully

I have been working with some examples to serialize and then deserialize an object created via: ::create_data()

Following the exmples found here, I am able to successfully serialize using the something like the code below:    instance = CSA_SecOpEnvServer_ServerComponentMgmt_AppControls_StopComponentCommandTypeTypeSupport::create_data();

    int buffSz;
    char *buffer;
    struct RTICdrStream mystrm;
    PRESTypePluginEndpointData endpoint_data;
   
    instance->processID = 1234;
    instance->timestamp = (RTICdrDouble)100.52;
    instance->description = "first time to go";
    instance->elementID = "1234";

    buffSz = CSA_SecOpEnvServer_ServerComponentMgmt_AppControls_StopComponentCommandTypePlugin_get_serialized_sample_size(
        endpoint_data,
        RTI_FALSE,
        RTI_CDR_ENCAPSULATION_ID_CDR_NATIVE,  // from cdr_encapsulation.h
        0,  //current alignment (start of buffer = 0)
        instance);
    buffer = (char *)malloc(buffSz);
    RTICdrStream_init(&mystrm);
    RTICdrStream_set( &mystrm, buffer, buffSz ) ;

    if (!CSA_SecOpEnvServer_ServerComponentMgmt_AppControls_StopComponentCommandTypePlugin_serialize(
        endpoint_data, //PRESTypePluginEndpointData endpoint_data,
        instance,      //const CSA_SecOpEnvServer_ServerComponentMgmt_AppControls_StopComponentCommandType *sample,
        &mystrm,       //struct RTICdrStream *stream,
        RTI_FALSE,      //RTIBool serialize_encapsulation,
        RTI_CDR_ENCAPSULATION_ID_CDR_NATIVE,  // from cdr_encapsulation.h
        RTI_TRUE,      //RTIBool serialize_sample,
        NULL)) {       //void *endpoint_plugin_qos
           printf("Serialize CSA_SecOpEnvServer_ServerComponentMgmt_AppControls_StopComponentCommandType, FAILED\n");
    }  

But I get complete failure when I try to deserialize the stream with:

        if (!CSA_SecOpEnvServer_ServerComponentMgmt_AppControls_StopComponentCommandTypePlugin_deserialize_sample(
            endpoint_data, //PRESTypePluginEndpointData endpoint_data,
            instance1alt,     // deserialize into this data packet
            &mystrm,       // struct RTICdrStream *stream,
            RTI_FALSE,      // deserialize encapsulation
            RTI_TRUE,      // deserialize sample
            NULL)) {         // endpoint_plugin_qos
               printf("DeSerialize CSA_SecOpEnvServer_ServerComponentMgmt_AppControls_StopComponentCommandType, FAILED\n");
        }

This failes for the first entity in the structure.

I am not sure, as there is little informatin regarding serialization, if there are other actions I must take

Thanks for any help given.
