'NoneType' object has no attribute 'evalWithCallback'

[ijgnd]

Thanks for keeping this add-on alive!

Your most recent update fixes #2 but now I get an error when I try to close an Add window. See the screencast/gif below.

I tried with the packaged version 2.1.25 for linux from apps.ankiweb and your add-ons Opening the same window multiple time and Keep model of add cards that I installed today into a new profile. I've looked into this for about an hour now and still don't have a solution. So I posted this issue.

The full error message is:

Anki 2.1.25 (898801eb) Python 3.8.1 Qt 5.14.1 PyQt 5.14.1

Before I made this problem description that documents the steps I took I also ran into these errors when trying to close an add window where I didn't document exactly on how to reproduce them. Maybe these are also useful for you.

and this (this occured after a note type change in the add window):

Once more: Thanks for creating and maintaining these essential add-ons!

Thank you for this exhaustive report. I'm surprised that the second error is new. There is very little I can do, because it's related to the way anki deal with windows. I'm hacking the system which is made for a single window in order to open multiple window. Doing it correctly without error about "Wrapped C/C++" would require to rewrite far too much things.

The first error should be corrected now. I've no idea yet for the last one. It's probably related to the current add-on, but I have no precise idea

Please update and let me know whether it got better: first problem should have disappeared

Thank you so much for this update. I'm not sure how long I would have taken me to figure this out (if ever). Now it mostly works for me. I could produce this error when closing a dialog.

Caught exception:

    return self.onReset(model=self.editor.note._model, keep=keep)
AttributeError: 'NoneType' object has no attribute '_model'

At the moment I'm trying out this minimal change to onResetSameModel and so far it seems to work:

from

return self.onReset(model=self.editor.note._model, keep=keep)

to:

model = None
if self.editor.note:
    model = self.editor.note._model
return self.onReset(model=model, keep=keep)

btw: for creating the gifs I use peek.

please update. Not perfect, but should be better already

works now for me. Thanks for the quick fix.
