preselect a radio button based on a value

Hi,

I am trying to preselect a  radio button based on a  value.
<input type="radio" value="A" checked name="allocate">
<input type="radio" name="allocate" value="H">
I always get the the value 'A' even though I have set the value for the node
to H.

Here is how I am setting the BToggleButton in the handleViewEvent:

String allocate = (String)session.getAttribute("allocate");

      if (allocate == null) {
        allocateSelected = 0;
      } else if (allocate.equalsIgnoreCase("H")) {
        allocateSelected = 1;
      } else {
        allocateSelected = 0;
      }

      Node         allocateNode =
allocateNodeList.item(allocateSelected);<==== this has the value of "H" in
it
      TemplateView allocateView = new
DefaultTemplateView(allocateNode,"name",
          new MapStateMap(modelProps));

     bodyTemplate.setView(allocateView);
     bodyTemplate.render(new DefaultViewContext(context));
     new DefaultDOMWriter().write(page,context.getResponse());

I also have a getItem(String key) : <=== never seems to get in here
   if (key.equals("allocate")) {
        boolean       selA    = false;
        boolean       selH    = false;
        BToggleButton btbComp = null;

        char          type    = poolDTO.getType();
        String        typeStr = new Character(type).toString();

        if (typeStr != null && typeStr.equalsIgnoreCase("A")) {
          selA = true;
        } else if (typeStr != null && typeStr.equalsIgnoreCase("H")) {
          selH = true;
        }

        btbComp   = new BToggleButton(BInput.RADIO,"allocate","A",selA);

        btbComp = new BToggleButton(BInput.RADIO,"allocate","H",selH);

        return btbComp;
      } 

Any help is appreciated or any example on pre-selecting a radio button based
on an input value would be great.
Thanks,
Vijay
