Added custom property with JSON export/import - grayed out

Ignition

I did a simple search and replace to add a Parameter to each UDT and then a custom property to each tag in the UDT with a binding to the Parameter.

Everything seems to work but I noticed that only the custom property I created manually in the GUI to then copy to other tags in the JSON file, is not grayed out.

Everything seem to be the same in the JSON file.

If I double click on the custom property and click ok on the popup it is no longer grey until I hit apply, then it's grey again.

If I delete it and then recreate it, it then looks normal.

When I look and the value of the tag instance in the tag browser it has the current value and I can change it and see it update. It just makes me wonder if I've corrupted the tags.

The grey italic font means it's a binding, black means it's a static value.

When you manually added the value to the json, did you write it as a binding or as a static string? (check what value the binding has and you'll see that it is an object, not simply a string value)

I have a script that auto converts static values that look like they should be bindings for this purpose exactly, so I can drag in a UDT from a plc from the device browser, extract to notepad++, find replace the opcitempaths with simple strings to make them dynamic, run through the script to convert anything to bindings if needed, and then import back

It's odd as this morning all of them are now grey. Maybe there is an issue if the UDT is already there and you import the JSON adding a Parameter and then a binding to it?

I just added the parameter in the parameters section.

    "Project_Phase": {
      "dataType": "Integer",
      "value": 1
    }

Then added the binding in the tags section.

      "Phase": {
        "bindType": "parameter",
        "binding": "{Project_Phase}"
      }

If I manually add a new custom property (Phase2) and bind it to the same 'Project_Phase' parameter, its not grey. While the one added Friday to the same tag in the same UST is.
