Editing Vendor Problem

[size=4]Whenever a vendor edits his details tabwise, upon clicking “Save” it does not save fields updated under all tabs.[color=#222222]It saves data only in the current tab which is not UX friendly. Upon clicking on “Save” or "Save & Close"button, it should save the entire current state of vendor details.So please could anybody help me out with this.[/color][/size]
