Not sure I’m following. When storing a form instance, it stores a ‘snapshot’ of the variables at that time. You can use it then later to retrieve that snapshot, but you’d still need to complete the form like normal.
e.g.
You have a textbox with the value test1
You hit save… You open that form with that text box again you get that value test1… Now you write the value test2 in the textbox and save again. If you open that form with the textbox again you still have the old variable value test1… Not as expected test2.
I don’t want to complete the form.
The use case is store a Form as often as u want and show the latest stored values
Sorry for reopen this old thread, but I am facing the same problem. The values are only saved the first time I POST “/form/form-instances” (when there is no previous form instance).
