The Ignition Designer does not load my view - instead it give the error
java.lang.Exception: Unable to get the view config: View config is undefined
Hovering over the page view in the project browser shows the preview, which is correct.
Launching a Perspective session and navigating to the view shows the correct view.
Examining the project files in a text editor - they look correct.
Sometimes restarting the designer clears it up.
Sometimes restarting the computer clears it up.
Today neither of those is working.
What's your Ignition version?
I'm having the same issue today. Recently I'd see this error on a view periodically, and closing all views would allow the view to open. When that didn't work I would save and exit the designer which again would allow the view to open. We are now seeing this on multiple views and closing the views / exiting the designer is not fixing the problem. I haven't tried shutting down the computer running the gateway yet. It's quitting time now, I'll give that a shot tomorrow.
