Internet Sales B2C - Display error message on the basket

Question

Hi, I am working on developments on the Internet Sales B2C scenario. I am trying to add new checks that are to be performed after the user has clicked the "Order" button on the basket.jsp page.
I have already created the action and the BO, BOM, and Backend object and I changed the action flow so after b2c/basketcheckout.do instead of calling b2c/maintaincheckout.do the system calls my own action, and if I have an error what I am doing is calling the addMessage() on the Basket object, and then sending the action flow to b2c/basketdisplay.do.
Everything is working fine except that the messages that I add to the basket are not shown when basket.jsp is displayed and I think this is because somewhere after the b2c/basketdisplay.do action is called and before the basket.jsp page is displayed the standard deletes any messages on the basket.
Should I change my program so instead of calling b2c/basketdisplay.do I call a different action to display the basket but keep my messages?
Does anyone has any better idea than what I am doing rigth now? I would gladly appreciate any help.
The config.xml that I have looks like this:
<action path="/b2c/basketcheckout" type="com.sapmarkets.isa.isacore.action.b2c.order.MaintainBasketB2CCheckoutAction">
               <forward name="login" path="/b2c/login.jsp"/>
               <forward name="basketEmpty" path="/b2c/order/basketEmpty.jsp"/>
               <forward name="checkout" path="/b2c/basketchecktopes.do"/>
               <forward name="ordersplit" path="/b2c/busy.jsp"/>
          </action>
          <action path="/b2c/basketchecktopes" type="com.orbitel.isa.action.CheckTopes">
               <forward name="checkout" path="/b2c/maintainCheckout.do"/>
               <forward name="basket" path="/b2c/basketdisplay.do"/>
          </action>
And the coding in my action is:
UserSessionData userSessionData = UserSessionData.getUserSessionData(request.getSession());
BusinessObjectManager bom = (BusinessObjectManager)userSessionData. getBOM(BusinessObjectManager.ISACORE_BOM);
SalesDocument miOrden = bom.getBasket();
if(miResp.equals("A"))
     return mapping.findForward("checkout");
else
     miOrden.addMessage(new Message(Message.ERROR, "system.forward.info", new String[]{"Ha superado el tope de sesion"}, null));
     return mapping.findForward("basket");
Thanks

You can do this using java script throwing an alert popup or you can check if the fields are initial in oninputprocessing and fill a variable like gv_error = 'Enter values of mandatory fields.' and display the same in layout using
<phtmlb:messageBar id = "messageBar"
type = "<%= gv_severity_str %>"
text = "error"/>
