Information

Current behaviour

Pass through from the "name" and "datatypeName" in the listener does not work is: "addressSpaceItems": [{ "name": "", "nodeId": "ns=2;s=Application.GVL_TTM.OpMode", "datatypeName": "" }]

Expected behaviour

Should be: "addressSpaceItems": [{ "name": "MachineStatus", "nodeId": "ns=2;s=Application.GVL_TTM.OpMode", "datatypeName": "Int16" }]

Minimal reproduction of the problem with instructions Inject nod -> Listener -> Debug

1. Make data available in your opc server
2. Add the nodes
3. Test

I think the issue may come from this line where the name and datatypeName are defined as empty, instead of using the values before the Listener node.

Edit: Line 411 and Line 477 may also be the problem.

@Teeffelen but there is no name and no datatype as you see ;) in this version of node-opcua it is only to fix on browsing for every monitor event to read that information from the key (nodeId) - maybe I missed some, then let me know ...

[biancode]

recipe to enhance:

• browse the information for NodeId on register monitored item
• save that information to a local dictionary
• fill up every monitor event with the dictionary information

[biancode]

That could better and easier be done with a browse once for the node-id if it is unknown and organizing them in a context dictionary inside Node-RED.
