Hi,
did anybody has problem with browsing tree of UaServerCpp server?
I am always receiving next error at same place while browsing through the tree::
26.02.2016 12:37:42,866 DEBUG OpcUaServerBrowser.dumpOpcUaAddressSpace – Reference Description: parent DA Profile Organizes node MultiStateValueDiscreteType
26.02.2016 12:37:42,867 DEBUG OpcUaServerBrowser.dumpOpcUaAddressSpace – Reference Description: parent MultiStateValueDiscreteType Organizes node Byte
26.02.2016 12:37:42,874 DEBUG OpcUaServerBrowser.dumpOpcUaAddressSpace – Reference Description: parent Byte HasProperty node EnumValues
Exception in thread “main” java.lang.RuntimeException: com.prosysopc.ua.client.AddressSpaceException: Cannot determine NodeClass for NodeId: i=7594 because the value is not good: DataValue(value=(null), statusCode=Bad_NodeIdUnknown (0x80340000) “The node id refers to a node that does not exist in the server address space.”, sourceTimestamp=null, sourcePicoseconds=0, serverTimestamp=02/26/16 11:37:42.8748958 GMT, serverPicoseconds=0)
at com.prosysopc.ua.client.nodes.UaVariableImpl.getDataType(Unknown Source)
I failed to find NodeId with i=7594 in the server tree by using UaExpert client.
Next node which client should read is:
parent Byte HasProperty node ValueAsText which has i=6175 and reading of it is fine in UaExpert.
Like there is some hidden node in the tree, I don’t have a clue.
Best regards,
Goran

This problem is already known and fixed in the C++ SDK. The fix will be included in the version 1.5.1 that is currently in testing.
The missing node is the DataType EnumValueType.

Hi Aro,
maybe it is good idea to rethrow this exception by uaVariable.getDataType()?

Since getDataType is introduced in the interface level (UaValueNode), which is common to the client side and server side objects, we cannot throw AddressSpaceException, which is a client side exception only.
Instead, it is converted to RuntimeException – which hides it away from the developer, unfortunately.
