My Vaadin 14 app occasionally displays the following message in a modal dialog box
vaadin TypeError: this._expandedButton is null
Has anyone else seen this? And does anyone have any thoughts or ideas as to the cause?
Hi,
This looks like [this issue]
(https://github.com/vaadin/vaadin-menu-bar/issues/85), the fix was included in vaadin-menu-bar-flow 1.0.3 which will be included in next maintenance release of Vaadin 14.1 and the upcoming 14.2.
Hi,
we have released [Vaadin 14.1.27]
(https://github.com/vaadin/platform/releases/tag/14.1.27) with this fix in place.
Enjoy!
