In the new version 3.1.4 i find the fantastic option to edit the article in menu-item.
There you can choose the menu item and the article and after saving the edit button comes.

But if i click the edit button my editor (joomlackeditor) is not loading and the screen does not look like i am used to it whet editing an article in the backend.

I upgraded from 3.1 and i use components:
admin tools
akeeba
nonumbers
rsform
rsfinder
acymailing
jck manager and jck editor

I do not think it has something to do with the components but maybe handy to know ;-)

Good luck and thanks for all the nice work!
