I use the latest version of vaadin and I get an error that I do not understand. The specificity of my project is that I made it migrate from vaadin 7 to 8; so it has the packages “compatibility”
I get the following error message:
java.lang.NoSuchMethodError: com.vaadin.ui.MenuBar.addItem (Ljava / lang / String;) Lcom / vaadin / ui / MenuBar $ MenuItem;

Have you changed the add-on version to newer as well? Context menu re-uses some framework components, and as there has been changes to those the add-on version needs to be aligned with the framework.

Yes i use the last version (3.0.0).
I updated the widget and emptied all the caches but I still get this error
