Href vs button in tileview

Question

I have a problem with retrieving values in tileview using href and no problems if I use a button. Here is the code which I use in both instances:
getPrimaryModel().setLocation(((TiledViewRequestInvocationEvent)event).getTileNumber());
String reqno = getDisplayFieldStringValue(CHILD_HIDDEN1);
RequestContext requestContext = event.getRequestContext();
javax.servlet.http.HttpSession session = requestContext.getRequest().getSession();
session.setAttribute("reqno", reqno);
System.out.println(reqno);
requestContext.getViewBeanManager().getViewBean(
RatePage.class).forwardTo(requestContext);
When I do the System.out.println(reqno) I get the expected record number for that tile. This same code using href and I always get null. Any help would be appreciated.

Remember, form values are not submitted back to the server when you use a link. This is standard HTML behavior. If you want information to be sent back to the server via a link, then you have a couple of options:
1) Set the value in the page session or client session BEFORE the link is rendered. Usually, the link's begin<field>Display() event is the best place to do this.
2) Use JavaScript to perform a form submit when the link is clicked
3) Substitute a button for the link
4) Add values to the link's URL via addExtraValue().
