Re: [Betterform-users] page unload and fluxProcessor.close()

[W.S. H. <ws...@gm...>]

Hi Daniele,

I understand your problem. I would propose keeping track of the
interaction, so instead of doing anything on unload you keep an active
stack of what's loaded into your iframe. Upon client leave you may prevent
client exit with a script, and either give the user an explanation or clear
the fluxprocessor session and force client exit/redirect yourself. My old
CMS worked with a blocking onUnload function to logout, but if I remember
correctly it didn't always execute. Note that in Betterform users are
notified by default when they exit a form.

load xform in iframe -> process xform -> check
parent.xformProcessed(someId) from xform
upon interrupt -> if not xformProcessed[someId] ==> *prevent client exit*

I'm not sure if the prevent client exit popup provided by betterform will
execute in an iframe, but that shouldn't be hard to find out. If not, you
can reproduce it yourself, and I'm sure you'll agree that it's always
legitimate to display once the xform is requested and not processed.
