I am getting this exception on ajaxSubmit when I have parameters.
java.lang.Long
java.lang.ClassCastException: java.lang.Long

Here is my facelet snippet. 
<a4j:htmlCommandLink id="deleteLink" action="#{editor.delete}"
 <f:param name="id" value="#{row.id}"/>
</a4j:htmlCommandLink>
This is the generated html. 
<a id="searchForm:searchTable:0:deleteLink" href="#"
onclick="return _JSFFormSubmit('searchForm:searchTable:0:deleteLink','searchForm',null,{'id':34} )">
This is the code with the exception: 
 protected void addExtraA4JParams(PostMethodWebRequest req, Map options)
 {
 Map params = (Map)options.get("parameters");
 for (Iterator i = params.keySet().iterator(); i.hasNext();)
 {
 String param = (String)i.next();
 req.setParameter(param, (String)params.get(param));
 }
 }
I haven't tried this yet, but I suspect it could be changed to something like this: 
 req.setParameter(param, params.get(param).toString());
Thoughts?
