ActionListener, restoreState issue
Hello,
I have a commandbutton with an actionListener tag set,
in the method that is invoked within the actionListener, I am trying to restore some other ui components on the view as follows:
UIViewRoot viewRoot = FacesContext.getCurrentInstance().getViewRoot();
UIComponent comp = viewRoot.findComponent("someId");
//do something with that component,
the problem is that several variables of that component are not accessible, this is due to the fact that I store them within the component by the saveState method.
I guess that these component properties are not accessible due to the fact that the component's restoreState must be invoked first.
So my question is - where is the right place to restore its state?
and am I right? the actionListener is being invoked -before- the restore state phase ?
thanks,
Asaf.

Yap,
It is my mistake,
well, my situation is a little bit more complex,
I have a component that extends HtmlPanelGrid (lets name it 'X')
in its encodeBegin method, I add some childs, one of them is an 'HtmlInput' component.
when the form gets rendered, I modify the child's input component, I am not sure how it works, but probably the value is stored automatically, probably the HtmlInput component take care of storing the specified value in form,
then I have two problems:
1) When I invoke the action via the ActionListener and get the 'X' component, The children of this component are not available, I get zero children.
2) When storing the X component's variables via 'saveState' method, I'm trying to fetch the new value of the child's 'HtmlInput' that was specified via the FORM, but I assume this value is not yet accessible in this phase,
so how exactly can I access the new stored value of that child component?
As always,
Many thanks,
Asaf.

look it below ;perhaps it can help you
public void decode(FacesContext facesContext, UIComponent component)
{
RendererUtils.checkParamValidity(facesContext, component, HtmlInputCalendar.class);
String helperString = getHelperString(component);
if (!(component instanceof EditableValueHolder)) {
throw new IllegalArgumentException("Component "
+ component.getClientId(facesContext)
+ " is not an EditableValueHolder");
}
Map paramMap = facesContext.getExternalContext()
.getRequestParameterMap();
String clientId = component.getClientId(facesContext);
if(HtmlRendererUtils.isDisabledOrReadOnly(component))
return;
if(paramMap.containsKey(clientId))
{
String value = (String) paramMap
.get(clientId);
if(!value.equalsIgnoreCase(helperString))
{
((EditableValueHolder) component).setSubmittedValue(value);
}
else
{
((EditableValueHolder) component).setSubmittedValue("");
}
}
else
{
log.warn(
"There should always be a submitted value for an input if it"
+ " is rendered, its form is submitted, and it is not disabled"
+ " or read-only. Component : "+
RendererUtils.getPathToComponent(component));
}
}
in belove code ,the value is from your component from page
and it is before setSubmittedValue()
it is page value ,is not locale value ?
