I'm trying build a generic code suggestionAction method, and to do so, I need the ability to pass a constant to that method. Is there a way to do this?

For example, something like this:

<rich:suggestionbox height="120" width="400" usingSuggestObjects="true" onselect="setSuggestion(#{rich:component('suggestion')});"
 suggestionAction="#{CodeCacheBean.autocomplete('CDOFFNSE')}" var="offense" for="offenseSearch" fetchValue="#{offense.code.value}" id="suggestion"
 minChars="3" nothingLabel="No Matches">
 <h:column>
 <h:outputText value="#{offense.code.value}"/>
 </h:column>
 <h:column>
 <h:outputText value="#{offense.description}"/>
 </h:column>
</rich:suggestionbox>

How can I pass the constant 'CDOFFNSE' to my autocomplete method? Since the normal way to call the autocomplete method is to simply reference the method in suggestionAction (for example, suggestionAction="#{CodeCacheBean.autocomplete}"), but the actual backing bean method accepts an Object as a method parameter, how do I add a second method parameter?

In other words, I would like to code my autocomplete method like this:

public List<CodeSearchBean> autocomplete(Object searchString, String codeName) { }

There have been posts that suggested that f:param or actionParameter can be used, but no working examples are shown.

Thanks in advance for any help you can provide.
