I would like to know how I can add a separator in the
"org.eclipse.ui.popupMenus" extension point. We can have a set of Object
Contributions and each one them has a set of actions. Each action has a
menubarPath which determines the path of this action. I do not know a way
to add a separator between two actions in an object contribution. The only
way is to add a new group path but in this case, all actions will be
placed at the bottom of the popup menu (which is not the required).
Furthermore, I do not want these actions to be placed in a sub menu; I
want them to be in the group path that I determined in the main menu.
