Answer 1

Add a VCE (Value changeListener Event) for your select as,
<h:selectOneMenu value="#{item.substituteHoliday}"
valueChangeListener="#{item.selectHolidayValueChangeListner}"
style="width:100%">
<f:selectItems value="#{employeeWorkingHolidayBean.subsholiday}"/>
<p:ajax event="change" update="subdate"/>
</h:selectOneMenu>
And in your valueChangeListener method assign new value to global variable as,
public void selectHolidayValueChangeListner(ValueChangeEvent vce) {
if (vce.getNewValue() != null) {
substituteHoliday = vce.getNewValue().toString();
}
}
Now, in your ajax method get the value of substituteHoliday and do whatever is required.
