I'm using scala 2.11.8 and Play Framework 2.3. I am submitting a form and managing the result through a controller. The controller returns a Redirect to a page flashing a certain message, either a success or an error message:
Redirect(routes.MyController.page).flashing("success" -> "All went well")
I then manage this message using javascript, so it can be seen in a modal:
@flash.get("success").map { message =>
<script type="text/javascript">
modalSuccess('@message');
</script>
}
All goes well, the modal is shown. Next I navigate to another page and use the Back arrow to go back and the modal is shown again. This is, of course, very weird for the user: he has just clicked back, it makes no sense that he sees a "All went well" message.
Previously, I passed these messages as parametres to the pages and returned a 200 OK:
Ok(views.html.page(message = "All went well"))
But the exact same thing happened because the request was sent again. I switched to Flash to solve this, but I can't seem to prevent it from showing when returning to the previous page.
Should I clear the Flash scope, or should it clear by itself, once the redirect is executed?
