I found the UISaveState page which showed that the approach below seems correct: http://wiki.apache.org/myfaces/SaveState
Still have a question though - on this page it states: "on page 2 should restore the entered data from page1 at the beginning of the phase cycles. thus once you reference scopebean on page2 you will get the values from page1, before the value of the submit are applied to the bean (if at all)." How do I position the t:saveState within the 2nd .jsf page so that will be restored at the beginning of the phase cycle? thanks -----Original Message----- From: Tom Butler [mailto:[EMAIL PROTECTED] Sent: Monday, February 06, 2006 10:45 PM To: 'MyFaces Discussion'; [EMAIL PROTECTED] Subject: RE: savestate question So you are saying that t:saveState saves state only for subsequent page views for the same page such as when using t:datascroller to scroll through a result set, but can not be used to save state between multiple pages? The approach I have gotten to work is to save the values for a backing bean between pages involves using t:saveState for the SAME backingbean across the pages - it works, but it would be helpful if someone with more experience could review to see if there are any issues doing this: PAGE #1 * Uses backingbeanPage1 (request scope) * Uses t:saveState to save state of backingbeanPage1 * Contains datatable with datascroller to scroll across rows in datamodel * Links to page #2 to view details for item from datatable PAGE #2 * Also uses t:saveState to save state for SAME backingbeanPage1 from page1 (note: when first come to page #2, values for backingbeanPage1 are intact) * When back to page #1 using a commandbutton, backingbeanPage1 state is restored properly Thanks Tom -----Original Message----- From: Martin Marinschek [mailto:[EMAIL PROTECTED] Sent: Monday, February 06, 2006 3:24 AM To: MyFaces Discussion Subject: Re: savestate question Hi Tom, Save state means that the information is stored with the state associated to a page. Now if you change to another page, and come back to the first one, the state of the first page has been lost, and the state of the saveState as well. regards, Martin On 2/6/06, Tom Butler <[EMAIL PROTECTED]> wrote: > > > > Found the problem here.
