Hi,
I have a question which is not really related to Prosys API. I have next peace of code:

AddressSpace addressSpace = uaClient.getAddressSpace();
List<ReferenceDescription> listOfReferences = addressSpace.browse(someNodeId);
if (null != listOfReferences) {
for (ReferenceDescription ref : listOfReferences) {
NodeId subNodeId = addressSpace.getNamespaceTable().toNodeId(ref.getNodeId())));
}
}

This is the only way which I found how from reference to reach NodeId. Please advice if there are better way.
Does call of method toNodeId(ExpandedNodeId n) return unique result, e.g. what will be the result if in same namespace exist
2 nodes with same browse name?

Best regards,
Goran

Yes, this is the best way to convert the NodeId and ExpandedNodeId. The NamespaceTable is the one that knows how the NamespaceURI and NamespaceIndex, which needs to be known.

You may also be able to use the UaNode objects, from which you can get the references:

UaNode node = client.getAddressSpace().getNode(prevId);
UaReference[] refs = node.getReferences();

Best regards,
