Re: [Wicket-user] breadcrumbs with wicket
Kind of a though question. None of the frameworks out there will have a solid answer for that. Generally what I do in these kind of situations, is either use a session property (in the typed session ofcourse) to maintain state between pages, or I make sure that I can rebuild the state I need e.g. by using page parameters or passing the models I need. The first is cleaner as it doesn't force you to the page level, but you shouldn't just put everthing in your session. An alternative way of looking at things is trying to avoid navigation from pages when you have to use cases you described, and work more with e.g. panel replacement etc. If you come up with good idea's, please share!

RE: [Wicket-user] breadcrumbs with wicket
The last app I worked on was done in tapestry. The way I implemented it there is almost exactly the way you describe. I had a session storage that kept the page stack and I can get the page state by capturing request.parameters and page's persistent properties. The big problem with that approach is that it pretty much blows the back button out of the water since there is no good way to sync the page stack in session. What I was thinking with wicket is to move the page stack into a base page, and when I create a new page pass the creating page into the constructor of the created page to create the breadcrumb. That way the new page clone the page stack of the creating page and add it into the page stack. I think this approach will eliminate the back button problem. There are a couple of things I still have to investigage. 1) should I put the creating page directly into the page stack, or should I clone it first. 2) is there a way to dump all versions except the current one since I wont need that information (which will force cloning of the page) 3) are there any problems with cloning a page 4) storing the page state object instead of the page, although I havent seen anywhere that lets you create a page from the page state yet Any thoughts will be greatly appreciated. IMHO a small framework for doing this would be a very nice addition to wicket since a lot of modern web apps can benefit from this navigation technique. I will happily donate any code if I get it working well.

RE: [Wicket-user] breadcrumbs with wicket
Bairos, Representing a navigation like this with an FA would create too many states. This is better represented as a stack of pages. Each time you navigate to a new page, that page captures the state of all the pages you used to get to it. See the use cases below.
