Hi all, We have got a couple of custom widgets in our application. I recently upgraded the pluggable-widget-tools of one of the widgets (8.3 to 8.18), but now I get some strange behavior that a widget sometimes disapears and will not be rendered anymore. When I delete the other widgets, that are still on an older version, everything seems to work fine. Also when I upgrade the pluggable-widget-tools of the other widgets as well, the bug seems to be solved. Did anyone else face similar issues when using custom widgets with different versions of the pluggable-widget-tools (one higher then 8.6 and one lower)?
