      Hi, im new in RichFaces and try to do the suggestion box example retired from RichFacesLiveDemo, but not work for me, i used exadel studio pro 4 in eclipse ide.
      I create de the bean SuggestionBox.java same on described in richfaceslivedemo, then i create a jsf page :

      <%@ taglib uri="http://richfaces.ajax4jsf.org/rich" prefix="rich"%>
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>

<html>
 <head>
 <title></title>
 </head>
 <body>
 <f:view>
 <h:form id="suggestionbox_form">


 <h:outputText
 value="Simple richfaces Suggestion Box test web application."
 style="font: 18px;font-weight: bold;" />
 <br />
 <br />

 <h:panelGrid columns="3" border="0" style="border: 1px solid black;">
 <f:verbatim>Suggestion Box will suggest you town names if it's started with the "a" or
 "A" letter</f:verbatim>

 <f:facet name="header">
 <f:verbatim>Input With Suggestion Feature</f:verbatim>
 </f:facet>


 <f:verbatim> </f:verbatim>

 <h:inputText value="#{suggestionBox.property}" id="text" />
 <rich:suggestionbox id="suggestionBoxId" for="text" tokens=",["
 rules="#{suggestionBox.rules}"
 suggestionAction="#{suggestionBox.autocomplete}" var="result"
 fetchValue="#{result.text}" rows="#{suggestionBox.intRows}"
 first="#{suggestionBox.intFirst}"
 minChars="#{suggestionBox.minchars}"
 shadowOpacity="#{suggestionBox.shadowOpacity}"
 border="#{suggestionBox.border}" width="#{suggestionBox.width}"
 height="#{suggestionBox.height}"
 shadowDepth="#{suggestionBox.shadowDepth}"
 cellpadding="#{suggestionBox.cellpadding}">
 <h:column>
 <h:outputText value="#{result.text}" />
 </h:column>
 </rich:suggestionbox>
 </h:panelGrid>

 <br />
 <br />

 </h:form>
 </f:view>
 </body>
</html>


      when i access the page and input some letter on input box i receive an alert error:
      request error: 500 internal server error
      message undefined

                  So, change the signature of the method.

                  public List autocomplete(SuggestionEvent event) {

 String pref = event.getSubmittedValue();

 //collecting some data that begins with "pref" letters.

 ...

 return result;

 }

                    I register the SuggestionBox class like managed bean then it works... :)
