Added a identifier to save the state for Menue item controllers.

[j5136p1]

Result = when you click on a menu item again it loads the last state of this controller
It is only a extension. If the identifier is empty the normal code will be executed

any example for this..?

If you have a list view for start and you click on a item to show detail. When you show the detail, change the menu item and go back your code shows the list view again instead of the detail view as it was before.
