sj:select issue - version 2.5 - Cannot use root element as list

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create an action with the following annotation:
@Action(value="some-action",results={
   @Result(name="LIST",type="json", params={"root","conditionTypes"})
})
public class SomeAction
    extends BaseAction
...

2.
And the following method
public String list(){
  conditionTypes.put("opt1","opt1"));
  conditionTypes.put("opt2","opt2"));
  ...
  return "LIST";
}

3. The jsp looks like:
<s:url id="remoteurl" action="some-action!list" />
<sj:select  
  href="%{remoteurl}"     
  id="conditionType"         
  name="conditionType"     
  dataType="json"
  emptyOption="false"         
/>

Wat is the expected output? What do you see instead?
At this point I expect the json output to populate the select options but I 
don't get any options.

I am getting JSON output:
{"10":"File Size","11":"Number Of Files","4":"File Content","9":"Last Modified 
Date"}

But jquery never seems to do the binding to the select element.

The rendered tag looks like:
<select name="conditionType" id="conditionType" jQuery1291246451525="25">

<script type="text/javascript">
jQuery(document).ready(function () {  
var options_conditionType = {};  
options_conditionType.datatype = "json";  
options_conditionType.type = 'select';  
options_conditionType.list = ".";  
options_conditionType.jqueryaction = "select";  
options_conditionType.id = "conditionType";  
options_conditionType.name = "conditionType";  
options_conditionType.href = "/MyApp/some-action!list.action";  
options_conditionType.datatype = "json";     
jQuery.struts2_jquery.bind(jQuery('#conditionType'),options_conditionType);   
});
</script>

What version of the product are you using? On what operating system?
2.5, windows.

Please provide any additional information below.
I would have thought that where the optional "list" attribute is left blank it 
would know to bind at the root element but it doesn't seem to work that way.
