Good day. Been using Vaadin for 2 1/2 years now with great success. Have not yet tried, not even downloaded CUBA yet, but will soon.
What release of Vaadin does CUBA use?
Is it your own fork of Vaadin?
it’s Vaadin 7.7.x i think. They have their own fork, but just for fixing stuff as I remember (https://github.com/cuba-platform/vaadin). Mainly it’s just regular Vaadin.
