Pharmadex - Old and outdated » Pharmadex Mozambique

Currently if user press this button, Pharmadex does not save information on actual page and sometimes raises run time error "detached object" Field validation does not work. This behavior must be changed to following:
user decides to press button "Back"
system warns user "changes will be lost, please save changes if need" and proposes do you want to continue... yes/no
if user will select yes, then system will display previous tab without save
if user will select no, then user can press "Save" button" and then will do any allowable action
