Hi guys, I just released the first version of the widget on GitHub - FBoissadier/mappView-opcuaviewer: A widget library with a opcua client browser widget The version 1.0.0 is available, please don’t hesitate to use issues directly on github if you have some problems or new feature request. I hop…

Hi … great job. Gave it a try - and it seems to work now! One thing which came to my attention: You need to configure the OPC-UA server alias … The widget should also work with an empty alias, as in a simple standard configuration you have no OPC-UA configuration => you also have no alias. CHH

Any volunteers for testing? I would like to hear success stories :slight_smile:

make sense. BUt before can you take a look on this error using (mapp View 6.3 and 6.1.5000)? [image]

Oh okay I see, that’s my bad. I was thinking that common of brease are shared between widget library but it’s not! I will make the change to include this in my widget lib. FYI : It work on my project when I use junction and not copy/paste my widget lib. So I will way my process to copy/paste the f…

Modification for this error is done you can get the new version on the repo :slight_smile:

Yes you are right! I also need to integrate error handling properly and add an OnError event.

Hi Florent, Is there a way to use the widget in mappView 5.24? I have a case right now where I could really use it.
