That worked Jon, thanks.
For the archives in case somebody else needs to know how to do this,
here is how I accomplished the task of resetting a form variable.
jsp code:
<x:inputCalendar id="deliverby"
monthYearRowClass="yearMonthHeader"
weekRowClass="weekHeader"
currentDayCellClass="currentDayCell"
value="#{OrderCtl.curOrder.deliverby}"
renderAsPopup="true"
rendered="true"
required="true"
styleClass="input"/>
Backing bean code:
FacesContext fc = FacesContext.getCurrentInstance();
fc.getApplication().createValueBinding("#{OrderCtl.curOrder.deliverby}").setValue(fc,
null);
