Claudia error: iItem.isVisible() is not a property or method when populating studio

[themanyone]

I got rid of the error by using iItem.isDisabled() instead, as suggested by the error message.
Not sure if there are any adverse consequences.

Affected version: Fedora package Cadence-1.0.0-0.17.20210316gitc146ff9.fc35.x86_64
Sorry if this has already been fixed in git.Internet is too slow to research this.
Merely sharing what I did.
