I have been thinking a little more about the BreadCrumbInterceptor. It
may be a blunt instrument but I was thinking it would be a fair
assumption to only include actions invoked via the GET method in the
bookmarks trail. This could be achieved in the interceptor with code a
bit like:
ActionContext context = invocation.getInvocationContext ();
HttpServletRequest request = (HttpServletRequest)context.get(HTTP_REQUEST);
if ("GET".equals(request.getMethod()){
// Do the magic stuff
}
I also thought that breadcrumbs of this nature would be really useful in
an application that stores the most recent searches (imagine a S2 app
using Lucene). In this scenario it would be good to additionally
include the querystring in the breadcrumb URL.
The only problem with these suggestions is that it makes it a far less
simple example (and I don't plan on paying for my feature requests - do
I qualify for the 3 for $250 yet?).
