Duplicate submit with F5
Locked
 
|
Hello, In our application, when the user submit the form, we have
an xpl file that call a webservice to store the data in a database, and if
there is no problem, the page-flow redirect to the start of application. And here, if the user press F5 (refresh), previous form is
submitted again, and is duplicated in database. How to forbid that ? Thank You. Julien.

Julien,
I think that a pretty secure way to prevent this is to generate a UUID in the form you serve to the user (e.g. stored in an instance on xforms-model-construct-done). When users save, you also store that UUID, and check that the previous save was done with a different UUID. If the previous save was done with the same UUID, then you have a case where the user is trying to save twice from the same form.
