DropDownChoice box does not display the value I selected

[shimin_q]

I have a DropDownChoice box that loads a list of values on load(), but when I
selected a value from the list, the selected value does not show up in the
box, even though it appears that getModelObject() does return the correct
value (the value I selected).  It's just the box does not display it.  I use
Wicket 6.3.0, locally tested using jetty server 6.1.26 and FireFox 17.0,
JQuery Mobile 1.2.0, JQuery 1.8.3.  Any suggestions or ideas?

Here is the Wicket code:

IModel<List&lt;String>> oxeNodeModel = null;
oxeNodeModel = new LoadableDetachableModel<List&lt;String>>() {
               private static final long serialVersionUID = 1L;
                @Override
                protected List<String> load() {
                        try {
                                List<String> names = null;
                                if ((profile!=null) && 
(profile.getType().equals(MetaProfileType.OXE) ||
profile.getType().equals(MetaProfileType.OXE_WITH_OT)))
                                        names = getOXENodeList();
                                                
                                        if (names == null)
                                                return Collections.emptyList();
                                        else {
                                                return names;
                                        }
                                        
                        }catch (Exception e) {
                                      return Collections.emptyList();
                        }
                }
        };

        oxeNodeBox = new DropDownChoice("oxeNode",
                new PropertyModel<String>(profile, "oxeNodeName"), 
oxeNodeModel);                               

        oxeNodeBox.setEnabled(true);
        oxeNodeBox.setOutputMarkupId(true);
        add(oxeNodeBox);

The html template is:

            
 
                 <label for="oxeNode" wicket:id="oxeNodeLabel"
class="requiredLabel">OXE Node</label>
                <select id="oxeNode" name="oxeNode" wicket:id="oxeNode">
                  <option selected>OXENode</option>
                </select>
