Cannot read property 'confirm' of undefined

I get this error in client-side when I load the page. I use Vaadin 14.1.16.
(TypeError) : Cannot read property ‘confirm’ of undefined.
Also, the textArea does not appear on the page.
The comment label is on the right side while I expected to be under the select component.
Has it to do with browsers? or is some bug? is there any workaround or definitive solution for it?

the same error was reported a year ago, no answer yet
[same error]

PD: Restarting Payara solved it, must be some cached issue. Maven and/or Netbeans are not cleaning well before a redeploy
