Re: [milo-dev] UaSubscription createMonitoredItems with multiple request

Indeed, that solved the problem.

Thanks!

You need to use a unique client handle for each monitored item you create. I think you'll see the values you expect once you fix that.

Hi Kevin,

I've setup a test case at: https://github.com/hmarius/opcuatestsubscription

Consider the following fragment:
-----------
BiConsumer<UaMonitoredItem, DataValue> consumer = (UaMonitoredItem u, DataValue d) -> {...}

ReadValueId readValueId1 = new ReadValueId(new NodeId(2, 10854),//DoubleValue
        AttributeId.Value.uid(), null, QualifiedName.NULL_VALUE);
ReadValueId readValueId2 = new ReadValueId(new NodeId(2, 10846),//ByteValue
        AttributeId.Value.uid(), null, QualifiedName.NULL_VALUE);
ReadValueId readValueId3 = new ReadValueId(new NodeId(2, 10849),//IntValue
        AttributeId.Value.uid(), null, QualifiedName.NULL_VALUE);


MonitoredItemCreateRequest request1 = new MonitoredItemCreateRequest(readValueId1, MonitoringMode.Reporting, parameters);

MonitoredItemCreateRequest request2 = new MonitoredItemCreateRequest(readValueId2, MonitoringMode.Reporting, parameters);

MonitoredItemCreateRequest request3 = new MonitoredItemCreateRequest(readValueId3, MonitoringMode.Reporting, parameters);


List<UaMonitoredItem> items = subscription.createMonitoredItems(TimestampsToReturn.Both, newArrayList(request1, request2, request3)).get();

UaMonitoredItem item1 = items.get(0);
UaMonitoredItem item2 = items.get(1);
UaMonitoredItem item3 = items.get(2);

item1.setValueConsumer(consumer);
item2.setValueConsumer(consumer);
item3.setValueConsumer(consumer);
-----------

The consumer of type BiConsumer<UaMonitoredItem, DataValue> receives the same UaMonitoredItem with DataValues corresponding to item1, item2, item3

I think that for each item the consumer should receive (item1,datavalue1), (item2,datavalue2), (item3,datavalue3), instead the consumer receives (item1,datavalue1), (item1,datavalue2), (item1,datavalue3)

Regards,

Marius
