Currently on Ignition 8.0.2. I encounter this error in the console whenever I attempt to click within the main designer pane or the component palate in the Ignition Designer. Any thoughts on why this may be happening?

What version of Ignition are you using? There's a bug with the same Exception noted that was fixed in version 8.1.8.
