[flexcoders] Resetting an application's view for new user
Hey flexers, I have a hefty AIR application with many different view combinations, forms filled with data, etc. When a user logs out and a different user logs in, I need the application to be reset so that everything looks as though no other user was previously logged in. I've ran into two solutions: 1) Reset all the forms, views, etc to their original state when the first user logs out. This can be tricky getting everything back to its initial state. 2) Make the main view (what would be the main application file in option #1) a separate component. When the user logs out, let the whole component get garbage collected. When the new user logs in, reinstantiate the main view to ensure its all in its initial state once again. With this option, there's not as much worrying about whether you've successfully reset everything since it's a brand new instance. However, processing time and memory management may be a new issue to deal with. So, I'm curious, how do you folks go about this in your projects? Thanks! Aaron
RE: [flexcoders] Resetting an application's view for new user
Here is what I do:
public function logOff():void
{
var ur:URLRequest = new URLRequest(_sAppUrl);
navigateToURL(ur,_self);
}//logOff
_sAppUrl comes from the browser: location.href

Re: [flexcoders] Resetting an application's view for new user
That's a good idea. I wonder if there's a way to do something similar in
AIR considering you can't make the AIR executable restart itself (from what
I know...without a bridge like Merapi). Maybe there's a way to essentially
reload the contents of the AIR app without actually re-starting the
executable?
Thank you very much for your feedback!

RE: [flexcoders] Resetting an application's view for new user
If you have an initialisation process which resets all state variables when the
application starts you could just run that process again?

RE: [flexcoders] Resetting an application's view for new user
Doh!, I missed the AIR. (I know, the fifth word, capitalized and all
that. Mea culpa.) Maybe someone with some AIR experience else will be
able to help.

Re: [flexcoders] Resetting an application's view for new user
Yeah, I think that would be akin to the first option described in my initial
email. The difficulty with that is making sure that all state variables
really do get reset. If new view combinations are added to the system
later, the developer is required to ensure they are also included in the
reinitialization process. Something that really ensures that everything is
at a clean slate and doesn't leave room for error on the developer's part
would be really nice. Tracy's recommendation is great for that since it
basically re-loads the SWF completely, but I'm not sure there's an AIR-based
alternative.

RE: [flexcoders] Resetting an application's view for new user
Yep true, Sorry Aaron I missed the initial email.
Tracys recommendation is simple and perfect for flex web based apps, Air apps
are another issue.
Could you perhaps hold all state variables in a bindable associative array or
object, then just rebuild the object? Are you using any recognised framework
for your app?

Re: [flexcoders] Resetting an application's view for new user
Yeah, something like that would probably work. On the other hand, I gave the
code at the bottom of this page a try:
http://www.docsultant.com/site2/articles/flex_internals.html
and it seemed to work very well for restarting the AIR app. I think I'm
going to take that approach. If anyone knows of a better approach, I'd love
to hear about it.
Thanks again,
