7.9.12

I’m getting some errors in the designer when I have a window open that don’t specify the component that the errors are coming from:

I know that I’m using a case statement to convert a tag value into a string, with one of the values corresponding to “Unclamping”, however there are a large number of these on the page. Also, I’d like to know why the component isn’t being specified.

How can I diagnose these?

Details:

You could try setting the `vision.binding.tag-binding` logger to debug or trace - it may have more contextual information that helps. Or do the nuclear option - duplicate the window, start deleting things until it stops happening 🙂

I don’t have a good reason for us not giving you the full path in all binding related errors, other than we just never have.
