You shouldn't need to use a4j:support. Are you using the rich:suggestionBox? If so you create a bean action called by the suggestionAction eg:

<rich:suggestionBox suggestionAction="#{searchScheduleHelper.suggest}" ...etc

An example of using a Database to populate the suggestionAction looks like this:

public List suggest(Object in) {
 String pref = in.toString().toLowerCase() + "%";
 Query q = entityManager.createQuery("select u from UnLocode u where lower(u.nameWoDiacritics) like :pref")
 .setParameter("pref", pref)
 .setMaxResults(10);

 ArrayList results = (ArrayList)q.getResultList();

 return results;
}

hello,

thanks to your reply. i think i have not explain my problem clearly.

what i search is when the user select a value in the list, i should rebuild some other list. suggestionAction is make for when we are typing in the text box. my problem is i have no way to know which line is selected by user.

<h:inputText value="#{bean.property}" id="test"/>
 <rich:suggestionbox for="test" width="200" height="200" suggestionAction="#{bean.autocomplete}" var="cap">
 <a4j:support event="onselect" reRender="output"/>
 <h:column>
 <h:outputText value="#{cap.text}"/>
 </h:column>
 </rich:suggestionbox>

As far as you have the input and suggestion in one region bean.property will be submitted on ajax request from support. So you may use bean.getProperty to get this value.

yes, you are right. i have bean.property,but sometimes we want the id not the description. i noticed the component htmlsuggestionbox has getrowdata, why not pass the rowdata to method onselect?

But having one of the objects property you may get another for this object i think..

Have you found a solution for this problem?

I would also like to pass the selected id to the bean so other information on the page could be updated.
