Thanks for your help. Yes. undo-tree-mode is a minor mode. The major
mode that I need to use emacs-state is undo-tree-visualizer-mode. 
But it doesnt work for that mode.

So again, the major-mode I need to be in emacs-state is
undo-tree-visualizer. It doesnt work though, for some reason. Maybe you
can suggest something.

P.S 

By the way, doing it for a minor mode -undo-tree-mode - worked, but too
well sort of speak: any buffer that had that as a minor mode would start
out in emacs-state.
