NullPointerException: Cannot read field "width" because "this.componentInnards" is null #532

Open benfry opened 2 years ago

benfry commented 2 years ago

Seen in 4.0, but not clear if this is downstream problems caused by https://github.com/processing/processing4/issues/530 or if it's an error triggered by changing between themes.

Haven't seen this since August; probably already fixed.

If you run into it, let us know (if this issue is locked, file a new issue and reference this one).

Aaaand… just saw it again.

May be weirdness with JProgressBar and show/hide calls vs updateTheme() or a behind-the-scenes updateUI() call.

Trying to use this library on version 4.3 and still experiencing this issue. Is there a temporary work around? Update : It is not an issue on 3.5.4
