Maybe this question has been answered in any post, but in these case I can't find it. In all tutorials that I follow, when they explain the section about "Generate code", they assume that in the New Project wizard I check something like "generator..." but I can't found it, and neither I can't found any like these when the projects are created.
I have installed Xpand also. But the problem has not been solved.
My Xtext version is 2.3.1. I suppose the tutorials are maybe outdate, I don't know.
