Submitted values lost - view is "refilled" everytime with model values
Got a problem with clay and flowScoped Spring beans. My view is everytime filled with the model values. The submitted values are lost. I can enter some data in my input fields and submit the form - if i left some required input fields empty, a message appears that something is missing, so far so good. However, the same field which i left empty - and all others i may have changed - are now populated again with values from my bean. What might cause this? I thought the component should remember this value and display this instead of the beans model value. Lifecycle stopped processing at Validation phase, so the components should not be cleared, any idea or tipps to debug this? Torsten smime.p7s Description: S/MIME cryptographic signature
Re: Submitted values lost - view is "refilled" everytime with model values
For JSF in general, this can be caused if you have input components in multiple forms (recommended practice is one form per page), or inside of UIData components (t:dataTable and t:dataList have a preserveRowStates=true attribute to handle this).

Re: Submitted values lost - view is "refilled" everytime with model values
Don't have any of these. Me uses one form and input components in this one form, without UIData.

How to initialize a bean before initial display
How do I initialize a bean before initial display? I want to populate bean values from database table. I can do it in the constructor, phase listener or by adding additional getter method to initialize the bean. But is there any better way? -- View this message in context: http://www.nabble.com/How-to-initialize-a-bean-before-initial-display-tf3652365.html#a10202810 Sent from the Shale - User mailing list archive at Nabble.com.

It looks like they are using a couple tricks for saving the FlowExecution. The FlowPhase listener [2] adds a non-visual component to the view root to keep state. It also adds the flow execution key to the view root.It looks like the flow key is used to restore the FlowExecution. I suspect the problem you are seeing has to do with the state not being resorted for the current flow on the postback. I would try setting some break points in the FlowPhaseListener.

Re: Submitted values lost - view is "refilled" everytime with model values
Hm did many Debug Points.
My RequestParameterMap got the entered values.
They are applied to my components in Phase 2 - setLocalValueSet is
called with set = true.
Now Phase 3 fails and Lifecycle goes to Phase 6.
Now a fresh tree is rendered , because my components does not got a
local value set - although the RestoreViewExecutor:
Application application = facesContext.getApplication();
ViewHandler viewHandler = application.getViewHandler();
// boolean viewCreated = false;
UIViewRoot viewRoot = viewHandler.restoreView(facesContext,
viewId);
if (viewRoot == null) {
viewRoot = viewHandler.createView(facesContext, viewId);
viewRoot.setViewId(viewId);
facesContext.renderResponse();
// viewCreated = true;
}
does call the restoreView and the viewRoot is not null.
If the view gets restored, why are the components "empty"?
I am a little bit confused now, i've missed something, but dont know
where to look now.
The PhaseListener is doing the flow story and seems to work correct - i
hope i did not missunderstand things.
Any hints?

Hi In that case you can initialize it in the init method or prerender method of the viewcontroller.

Re: SV: SV: How to initialize a bean before initial display
Thanks for your reply. I am now extending AbstractViewController and implemented the init() method but this method is never called. do I need to configure anything?

Hi If its not called, you must have placed it in session-scope (it must be request-scoped), or it is not mapped against the view in faces-config.xml Hermod -Opprinnelig melding- Fra: AM101 [mailto:[EMAIL PROTECTED] Sendt: 26. april 2007 23:54 Til: user@shale.apache.org Emne: Re: SV: SV: How to initialize a bean before initial display Thanks for your reply.
