Reading Nodes on Client side fails with code generated classes

Hi,
I found a very strange behaviour when trying to read nodes with codegeneration on the client side.

In my server a new OPC UA Program Subtype is created with createInstance(…). This works perfect. The type (and it’s subnodes) is created. I can browse it and read the values with UaExpert.

On the client side I use the codegenerated classes. And i can get the Object via:
LinImpl myLin = (LinImpl) fubsClient.getConnection().getClient().getAddressSpace().getNode(nodeID);

This also seems to work, no error, i can also call stuff like myLin.getDisplayName() etc.

But when I try to access a subnode of this type in the ImplBase e.g. this.getCurrentState() I get an error, that the mandatory node is missing (also it is there, I can see and read it in UaExpert). Also this.getComponents() return null. For some reason, it doesn’t find the subnodes.

When I directly go over the BrowsePath and try to get the NodeIds of subnodes there, it works?!

Something odd, I think. I suppose the HasComponent references are in place correctly – or are they maybe something else?

If they are HasComponent, could you run your client side code with DEBUG-level logging set for AddressSpace?

For example with log4j:

log4j.logger.com.prosysopc.ua.client.AddressSpace=DEBUG

And show what it prints for ‘getNode()’

Thanks.

Hi,
that was a good advice: It seems like I can get the nodeId of the node, but then when trying to get the UaNode it doesn’t find it?!

Looks like there is something quite wrong here:

SourceId=nsu=http%3A%2F%2Fkuka.com%2Frobot_fubs%2F;i=1002 TargetId=nsu=http%3A%2F%2Fkuka.com%2Frobot_fubs%2F;s=Create2, ReferenceType=HasTypeDefinition 
SourceId=nsu=http%3A%2F%2Fkuka.com%2Frobot_fubs%2F;s=Lin0 TargetId=nsu=http%3A%2F%2Fkuka.com%2Frobot_fubs%2F;i=1002, ReferenceType=HasTypeDefinition 
SourceId=nsu=http%3A%2F%2Fkuka.com%2Frobot_fubs%2F;s=Lin1 TargetId=nsu=http%3A%2F%2Fkuka.com%2Frobot_fubs%2F;i=1002, ReferenceType=HasTypeDefinition 
SourceId=nsu=http%3A%2F%2Fkuka.com%2Frobot_fubs%2F;s=Lin2 TargetId=nsu=http%3A%2F%2Fkuka.com%2Frobot_fubs%2F;i=1002, ReferenceType=HasTypeDefinition 
SourceId=nsu=http%3A%2F%2Fkuka.com%2Frobot_fubs%2F;s=Lin3 TargetId=nsu=http%3A%2F%2Fkuka.com%2Frobot_fubs%2F;i=1002, ReferenceType=HasTypeDefinition 
SourceId=nsu=http%3A%2F%2Fkuka.com%2Frobot_fubs%2F;s=Lin4 TargetId=nsu=http%3A%2F%2Fkuka.com%2Frobot_fubs%2F;i=1002, ReferenceType=HasSubtype

So the node has 5 HasTypeDefinition references and one HasSubtype reference. Only 1 HasTypeDefinition is allowed and HasSubtype should only be present in Type nodes.

This maybe came here, because I added an isntance of the type a few times. This is the output, if only one instance was added:

Oh yes, sorry I misinterpreted. That output was from reading the Type Node (Lin), and those were references from the instances to this type.

But yes, looks like the server would not find any references for the instance (Lin0) and just gives the Bad_NodeIdUnknown for some reason. How do you create the instance and add it to the NodeManager in the server? Have you modified the handling of ‘Browse’ in your server: do you manipulate the NodeManager or use a NodeManagerListener?

Good morning Jouni,
ok, so in the server first the codegenerated models are loaded with registerModel() and
getAddressSpace().loadModel(getClass().getClassLoader().getResource(“….xml”).toURI());

Then the instance is created by
LinNode myprog = createInstance(LinNode.class, name, programId);
myprog.setProgramName(name);
myprog.setState(ProgramState.Ready);

On the serverside, also accessing the subnodes works:
myprog.setCurrentPosition(new Double[] { 1.0, 2.0 });

The handling of Browse is not modified and I didn’t create any NodeManagerListener, but several NodeManagers for the different namespaces. In UaExpert, everyhting works well, when browsing the instance.

This is quite strange. Would you be able to share the project (by email to uajava-support at prosysopc.com), so I could try it out and see if I understand what is going on?

I’m clarifying with my boss, if or how we can share the project. Mean while I found out, that when I execute the same code on the server everyhting works fine:

browsePath = new OPCUABrowsePath();
browsePath.append(null, “Objects”);
browsePath.append(“http://ns.com/fubs/”, “InstanceName”);

indexedBrowsePath = browsePath.generateIndexedBrowsePath(getServer());
nodeID = null;

try {
nodeID = server.translateBrowsePathToNodeID(indexedBrowsePath);
} catch (Exception e) {
log.error(“Path for create method could not be found”, e);
}

UaNode test = null;
try {
test = server
.getAddressSpace().getNode(nodeID);
} catch (StatusException e1) {
e1.printStackTrace();
}

When I run this on the client I get this

com.prosysopc.ua.StatusException: Bad_NodeIdUnknown (0x80340000) “The node id refers to a node that does not exist in the server address space.” StatusCode=Bad_NodeIdUnknown (0x80340000) “The node id refers to a node that does not exist in the server address space.”

error message is thrown from line
test = server.getAddressSpace().getNode(nodeID);

But the nodeID is correct, if I give a e.g. wrong Namespace, i get a different exception.

The strange thing is, that on the server getNode() throws a StatusException. On the client it throws a Service and AddressSpaceException. But a StatusException is written on the console, i guess by the logger.

OK, maybe the plain XML model would be enough to see if the problem can be reproduced here.
