I have the following straightforward code in my Seam component:

      try {
         widget = queryService.findByNumber(number);

         if (widget.isOutOfStock()) {
            facesMessages.add("out of stock.");
         }
         else {
            addWidgetToOrder(widget);
         }
      }
      catch (NoSuchWidgetException e) {
         facesMessages.add("There is no widget with that number.");
      }

The queryService component does a basic lookup, and NoSuchWidgetException wraps the JPA NoResultException thrown  inside queryService.findByNumber if the lookup fails.

The problem is that my <h:messages> component gets filled with the right message (There is no widget with that number.)...but then followed by a new line and the message Transaction failed. 

Why do I get this message when I wrap the JPA exception in one of my own?  I don't want to change the text in messages.properties, so how can I get rid of this Transaction failed message in this instance?

Thanks.
