I am developing an app which is a form & I want the user to be able to go back to a previous page and editing some of the details if they wish. For this I was using the Back Button event and invoke a database service to map the local storage variables to the relevant fields in the form.
I previously had this working but for some reason it has now stopped working! I have deleted the original service during my troubleshooting, what type of DB service should be run for this? Create/List/Read/Query? Is there any additional javascript necessary for this?
