Re: Direct usage of myfaces out of a Java program and save/restoreState issues

[Ricardo Tercero Lozano]

The only time frame where views are stored is between a RENDER_RESPONSE end (the view is serialized) and the RESTORE_VIEW of next request. At the end of that request there is a new RENDER_RESPONSE phase and a new view is created, so you are *almost* right. Views are stored but not used at all except for the 'back button' issue. If you press the back button one or some times, the view restored after submit in RESTORE_VIEW phase is not the last view stored, but the corresponding to that submit (the right view to restore is located by a 'jsf_sequence' hidden parameter).

Savestate stores an object in view in time between RENDER_RESPONSE and next RESTORE_VIEW. This is the way an object is *maintained* between requests.

So answering your questions, yes, navigating to a view ( as a consequence of JSF navigation) doesn´t restore its previous state, creates a new one.

Ah, that would explain the behaviour. So, every time I leave a view, that
one is destroyed *completely* and re-entering it does not lead to calls to
restoreState, right? I am a bit confused, because when leaving the view
I can see calls to saveState and that means that this data will not be
used then.

Thanks,
