mansi commented on MYFACES-4036:
--------------------------------
Thanks for the suggestion
This issue also exists when we disable PSS.
So its only components inside the datatable for which the input value is not
persisted when validation fails while if we move these components outside the
datatable the input value is persisted when validation fails .
Also bridge invokes the JSF lifecycle and after that it saves the state using
processSaveState(). As you mentioned about buildView ,it will be executed when
JSF lifecycle is invoked .So if we replace processViewState with buildView then
the buildView would be invoked twice i.e once when JSF lifecycle is executed
and second time when we want to save the state in bridge .
Also processViewstate returns an object but buildView is a void method . Can
you please suggest how can we get the viewstate after JSF lifecycle is executed
. Please share your thoughts .

> Key: MYFACES-4036
> URL: https://issues.apache.org/jira/browse/MYFACES-4036
> Project: MyFaces Core
> Issue Type: Bug
> Affects Versions: 2.2.10-SNAPSHOT
> Environment: WebSphere Liberty 8.5.5.8, MyFaces 2.2.8, IBM JSF
> Portlet Bridge 1.0
> Reporter: Hank Ibell
> Priority: Minor
>
> A JSF portlet with input fields inside a h:dataTable component will lose
> their local values if validation fails, even when rowStatePreserved is set to
> true.
> The IBM JSF portlet bridge calls processSaveState() on UIViewRoot so that the
> bridge can restore the view state on their RENDER request. After looking at
> UIData, it looks like _initialDescendantFullComponentState is lost between
> Portal's ACTION and RENDER requests (a new UIData object is created on the
> RENDER request). Unfortunately, UIData's _rowDeltaStates will not be restored
> without its initial state.
> It looks like UIData should also save/restore
> _initialDescendantFullComponentState in its saveSate()/restoreState() methods
> since it may be needed to restore _rowDeltaStates.
