First namespace

[Darjohka]

I have a problem reading a value from the internal OPC server. I use the QuickOPC toolkit and get the error message:

"The first namespace in the table must be the OPC-UA namespace."

After loading example.xml the namespace array contains:
[0] urn:freeopcua:python:server
[1] urx:mycompany:myproject

The screenshot that comes with the folder opcua-modeler (screenshot.png) shows index 0 with the value http://opcfoundation.org/UA/.

So, is the index 0 problem a bug or can I configure it somehow?

Since I used git clone, I assume, I have the most recent version ...

Best regards!

I think it's a bug. If you open modeler and just start with a brand new model, then add some of your stuff and export it does it work? Instead of using example.xml.

Starting with a brand new model leads to the same problem ...

When do you get that error? It looks like we remove the address space 0 in modeller. I do not remember why... there was a reason.... Anyway when you export xml, it should not change anything since when importing it, the server will allready have namespace 0 defined...

there was a bug, fixed now in master

Sounds great! I'm away on business. Next Thursday I will have time to test the connection with QuickOPC toolkit ... Thank you in advance!
