Hi, i was using an old version of messagebox, now it's working perfectly, Thanks!
HI, i've got an error when i try to create MessageBox. at line 324 mainLayout = new VerticalLayout(); al line 325 mainLayout.setImmediate(false); problem is that in VerticalLayout there is no such method, maybe they deleted it on this version of Vaadin (vadin.server-8.0.5) Let me know if I'm right or I'm misunderstanding something
