Hi all
This morning I found that if a page element is repeatedly pushed to
the PageStack, repeated instances of the page are created on the
PageStack, as shown by the breadcrumb indicators on the top of the
page(s).
So why try and repush a page?
What I really wanted to do was to pop back to the previous page, but
pass some information back to the previous page. As the pop() method
does not allow properties to be set, but push() does, I had misused
push(). On Harmattan this worked well enough (or rather if it was
adding multiple page instances, I did not see it due to the lack of
breadcrumbs).
Looking closer at the code of the app where I found the problem I
discovered that for another page wanting to pass info back I had taken
a different approach. Here I had used pop() but before calling pop() I
had directly passed info to the previous page by setting properties of
that page.
Both approaches are shown in this mini-throwaway demo.

To my mind the cleanest solution would be if Sailfish supported:
pop(page, properties, operationType)
Cheers
Chris
