Two listbox and method refresh

[endrinas]

Hello,

I have problems with listbox component and the method refresh.
I'm trying to do this:

I want to have 2 listbox components in the same page. When I select one item in the first lisbox, I want to refresh de second one with a bakinbean.

I tryed to implement it like the examples in the TLD but I always obtain a javascript error

'null' is null or isn't an object

My jsp code is like this



<webuijsf:listbox binding="#{EditaDatos.list}" id="list"
                            items="#{EditaDatos.informes}" />

<webuijsf:listbox binding="#{EditaDatos.listbox1}" id="listbox1"
                            items="#{EditaDatos.listbox1DefaultOptions.options}"
                            onChange="refreshList()"  
                            valueChangeListenerExpression="#{EditaDatos.obtenerInformes}"/>

<webuijsf:script>
      function refreshList() {
                        var domNode = document.getElementById("form1:list");                
                        return domNode.refresh("form1:listbox1");
                                                   
}
</webuijsf:script>

Can anybody help me?

Thanks

Are you certain a valid HTML element was obtained (i.e., domNode is not
null)? Perhaps you have the wrong ID?
