Leonardo Uribe commented on MYFACES-4036:
-----------------------------------------
After doing some test I have found this problem could have more considerations
to do.
In JSF 2.1, it was introduced an interface called TransientStateHolder.
According to the javadoc, the idea of this API is:
"... This interface is implemented by classes that need to save state that is
expected to be available only within the scope of the current request. ..."
This API is used in very, very few cases (only used once in JSF 2.2 core to
hold FaceletState temporally), but in portlet case, it is expected that when
you call saveState(...) over the component on a phase different than render
response phase, this transient state should be saved with the component state
too.
This behavior was not originally thought (because in the JSF EG we never went
that far to consider portlets) but it has a lot of sense, and in the "spirit"
to make things just work, I think we need a new issue for this behavior too.

> 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.
