How to Read Local JSON File in UIX?

I would personally not include the JSON file in the UIX application, but instead load it from the server.  This gives you maximum compatibility.

In our case, we want to get different commandName from a JSON file based on input passed while calling extension method. But the problem is - we get the commandName from extension method after creating custom command. So it get's the commandName defined in UIX not from VAF Extension method. That's why tried to read JSON from UIX.

But as you suggest to do from vault application, how to call the extension method so that I get the intended commandName before creating custom command with the name?

Wasn't this another forum thread? Why are you starting multiple threads about the same thing?  I seem to recall I replied to you there and I don't recall suggesting you went down this route.  Your issue there was simply timing (you needed to create the command after you've loaded the data, not before).

If you're still having issues with that then I suggest you add a comment to this thread linking to the previous question, then continue that one.

Sorry, my bad. I was not able to fix the issue yet and tried to describe why wanted to parse JSON from UIX instead of VAF.

Anyway here goes the question link of previous discussion - community.m-files.com/.../is-there-any-way-to-hide-the-context-menu-based-on-license-status
