How do I give this bug a thumbs up? Asking for a frustrated friend...

ItaloLeandro02 commented 1 month ago

Froala 4.2.1 does not have this issue.

coreequip commented 1 month ago

This bug still present in v4.3.0.

Steps to reproduce:

It will end up in a 3rd level list item and the editor is throwing the mentioned exception.

mikebertiean commented 2 weeks ago

Same issue.

@wvddrss @brambilliet @coreequip any luck with a workaround here?

coreequip commented 2 weeks ago

Not really. Catching the exception in frontend while waiting for a patch from Froala.

mikebertiean commented 2 weeks ago

@harasunu-narayan any recommendations on this one?

brambilliet commented 2 weeks ago

@ItaloLeandro02 taloLeandro02

Froala 4.2.1 does not have this issue.

Yes it does, even v4.3.0

mikebertiean commented 2 weeks ago

support@froala.com if you haven't reached out yet :) Waiting on a response.

I haven't been able to find a good workaround yet that will make the editor useable.
