I didn't mention anything about a value change listener.
You have
value="#{editProfileAction.updateUserLocations}"
which I think is the cause of your problem.
And I didn't say it was complaining *about* the component id. I'm saying
it is complaining about the component which has an id of
"userLocations". You appear to have interpreted this as a problem with
the *method* getUserLocations which I don't think is the case.

Is the valueChangeListener supposed to return a String? I was under the
impression that it's supposed to return void, like
ValueChangeListener.processValueChange(ValueChangeEvent event).
Why would it be complaining about the component id?
I wasn't quite clear enough in my description. This particular select box
is expected to contain, and to submit, several items, so the mutator
(setter) will also take an array. It's a Collection, owned by a user.

referring to the component id, not a method name.
Value should be a binding to a property (ie get/set methods). When
rendering, the getter is called and expects a value that matches the
"value" property of one of the SelectItem objects from the f:selectItems
child.
When the user selects a different SelectItem from the list, the setter
is called, passing the "value" of whatever SelectItem the user chose..

I am getting a converter error when trying to pass an array of
SelectItems to
a selectManyListbox. Isn't this component designed to handle an array?
Why
would I need a converter? Note, these are pre-selected items. That's
why
the value of the selectManyListbox is the same as <f:selectItems/>
JSF:
<h:selectManyListbox immediate="true" id="userLocations"
value="#{editProfileAction.updateUserLocations}"
size="11" styleClass="selectBox"
valueChangeListener="#{editProfileAction.updateUserLocations}">
<f:selectItems value="#{editProfileAction.userLocations}"/>
</h:selectManyListbox>
Java:
private SelectItem[] userLocations;
...
public SelectItem[] getUserLocations() {
return userLocations;
}
public SelectItem[] getUserLocations() {
return userLocations;
}
...
Result:
java.lang.IllegalArgumentException: Value is no String and component
alertsSubView:alertsForm:userLocations does not have a Converter
