Using Map<String,List<String>> in <s:selectItems>

[ssahni]

I need to display a city dropdown which will change on the basis of state dropdown. So I defined them in the bean(used as sM in .xhtml) as:

    List<String> states;

    Map<String,List<String>> cities;

In .xhtml, for states dropdown I am using :

                            <h:selectOneMenu id="state" value="#{tS.selectedState}" >
                                                        <a:support event="onchange"  reRender="city"></a:support>
                                                        <s:selectItems value="#{sM.states}" var="i" label="#{i}" />
                                                    </h:selectOneMenu>

It is working fine and I get values being displayed in dropdown

In same .xhtml, for cities dropdown I am using :

     <h:selectOneMenu id="city" value="#{tS.cityField}" rendered="#{tS.selectedState != null}" >
                                                         <s:selectItems value="#{sM.cities[tS.selectedState]}" var="i" label="#{i}" />
                                                    </h:selectOneMenu>

Code in the bean annotated as tS in .xhtml is

    private String selectedState;

    private String cityField;

//Getters and setters

Now when I run the page, city dropdown does not get rendered at all, inspite of changing the value in state dropdown.I do not get any exception also.

Please tell me why it is behaving so? If I print the value of selectedState , the value is printed and is changed on changing the state in dropdown.

Please help.

My guess:

The 2nd h:selectOneMenu is not rendered during the initial rendering, so when it is updated the client framework doesnt know where to put the replacement from the AJAX response.

Try placing the h:selectOneMenu within an a:outputPanel and reRender that instead.
