Good Morning I am working on a project but I have a problem. In fact I made MenuItems and Buttons with SceneBuilder and I have added a method "ouvrir" that should be activated when we click on the buttons or the menuItems. In fact, I take the id of the source of the event to open a tab. This method works for the buttons but not for the MenuItem. When I click on the MenuItem,it generates an error.
