I’m coming back to a visual component library I was working on a few weeks ago, and was surprised by the above message. It occurs when I try to run the library’s test-bed (app). Location: the top of one of my form constructors, where it calls
self.init_components(**properties)
To the best of my recollection, I haven’t changed the Form (FrameDateInRange) where the error occurs. It consists of nested components. Currently, none of them will display in the Designer pane, although they do appear in the form’s pull-down component list. (May be a related problem.)
I’ve tried shutting down my browser (Chrome), and starting again in a different one (Firefox). I’ve tried Exporting and Importing the app. No luck there.
“SK” suggests that it might have something to do with Skulpt – and since these are components for the browser, that makes a certain amount of sense. (I did not find SK anywhere in my own code, and it’s not a name I’d normally pick.)
Just in case a concrete example helps, I’m emailing a link separately.
