Hi,
I'm using MyFaces 1.1.6 and Tomahawk 1.1.9.  I have this selectOneMenu ...

                                <h:selectOneMenu required="true"
validator="#{historicalTour.validateTime}" styleClass="hourMenu"
id="historicalTour1st_Preference_Hour"
value="#{historicalTour.prefs[0].time}">
                                <f:selectItems 
value="#{historicalTour.timePrefItems}"/>
                                </h:selectOneMenu>

When another text field on the page changes value, I would like to
re-populate the select menu with new options.  I have discovered I just
can't simply do that with Javascript, because when I submit the form I get a 

"Value is not a valid option"

error.  Any ideas how I can change my select menu options and keep JSF
happy?

Thanks, - Dave
  
You can use a Value Change Listener in your text field like this
<h:inputText valueChangeListener="#{BackingBean.methodName}" 
onchange="submit()" />

in your backing bean

public BackingBean implements ValueChangeListener {
    public void processValueChange(ValueChangeEvent valueChangeEvent) {
   }

   public void methodName(ValueChangeEvent vce) {
      //change your select menu options
   }
}
