and the login view is missing the fields to enter username and password as well as the buttons.

I am using the pdf dependency with this maven coordinates:

org.vaadin.alejandro
pdf-browser
3.1.0

Are you able to provide a minimal reproducible example that I can run to diagnose the issue?

Hello, I have the same problem/issue.It even took a while until I could assign the disappearance of the login mask to the installation of the dependency of the pdf-browser:

org.vaadin.alejandro
pdf-browser
3.1.0

to the installation of the dependency.

so it seems that the problem does not only occur with me.
At the moment i have not yet found a solution nor a cause.

PS: my project is based on the offical vaadin project “Java tutorial: Java web app tutorial series” (in the meantime, of course, further developed ;-) )
Updated tutorial here: https://youtu.be/bxy2JgqqKDU

Otherwise, that would be exactly what I need (generally running, but not in my project :-( ).

Not sure what causes the issue. The add-on is compatible with Vaadin 14.5.3. Never tested it with later versions.

5

I believe the issue at hand is a polymer version conflict. I had a similar issue when upgrading to Vaadin 14.8.0. Once I removed the add-on, everything worked as normal.

Any chance getting the viewer upgraded to Vaadin version 14.8.1?

Thanks
