vt7.1 - vtlib - VTiger_Field->save() does nothing for an existing field

In /vtlib/Vtiger/FieldBasic.php the function save() checks to see if the field has an existing id or not. If it does then the __update() function is called, and if not then the __create() function is called.

The __update function only does

self::log("Updating Field $this->name ... DONE");

There is no update of anything whatsoever. Can the function be fixed to actually save the edited field OR at the very least remove the very misleading message!!
