I am using a <rich:autocomplete> component but the suggestion box just doesn't show up. Here is a simple case I'm trying:

XHTML:

<h:form id="amit" prependId="false">
  <rich:autocomplete mode="ajax" minChars="1" autofill="true" var="station" autocompleteMethod="# {segmentationBean.autocomplete1}" >
    <rich:column styleClass="sexy">
      <b>#{station}</b>
    </rich:column>
  </rich:autocomplete>
</h:form>

JAVA:

public List<String> autocomplete1(String request){
 List<String> suggestions = new ArrayList<String>();
 suggestions.add("test 1");
 suggestions.add("test 2"); 
 suggestions.add("test 3"); suggestions.add("test 4"); return suggestions;
}

This shows up in logging (using <a4j:log/>)

error[14:47:03.644]: Received 'error@malformedXML' event from <span id=j_idt5 class="rf-au" ...>
error[14:47:03.644]: [status=200] During update: javax.faces.ViewState not found

Also i can see the suggestion if i switch the mode to "Client"
