Thomas Andraschko commented on MYFACES-4425:
--------------------------------------------
i found that when i modify #saveState of UIRepeat like this, it works fine:
{code:java}
@Override
public Object saveState(FacesContext context)
{
if (context.getViewRoot() != null)
{
if
(context.getViewRoot().getAttributes().get(ViewPoolProcessor.RESET_SAVE_STATE_MODE_KEY)
== ViewPoolProcessor.RESET_MODE_SOFT)
{
_dataModelMap.clear();
_isValidChilds = true;
}
else if
(context.getViewRoot().getAttributes().get(ViewPoolProcessor.RESET_SAVE_STATE_MODE_KEY)
== ViewPoolProcessor.RESET_MODE_HARD)
{
_dataModelMap.clear();
_isValidChilds = true;
_rowStates.clear();
}
}
Object values[] = new Object[3];
values[0] = super.saveState(context);
values[1] = null;
values[2] = UIComponentBase.saveAttachedState(context, _rowStates);
return values;
}
{code}
> Input value not saved/restored in state when inside UIRepeat
