We are doing this on our site www.swhp.org . I have heard this called bread crumb's by a few of the vendors that have rolled through our shop, so it is an accurate name. I have also heard it referred to as a history trail but I think bread crumb is the most common. We have a history portlet across the top of the pages that basically keeps track of a stack to push and pop link information on and off to build the bread crumbs. Here is a list of some of the issues: - Every link (action) selected has to send a message to the history portlet telling it what was done. This is no big deal since all the portlets on our site broadcast this information to all portlets on the page. It is a big deal when trying to make a generic bread crumb portlet as not all portlets will broadcast link information and if they do there is no standard for what they will send. - It is extremely difficult to share information between pages. So the bread crumb trail is only for pages visited with in the particular page on the portal. This sounds like double talk but if you browse around our health plan site you'll notice that there are several areas Visitors, Members, Employers, and so on. Each one of these is a separate page in the portal. So each one will keep its own bread crumb trail. - The links are dynamically generated so you can not keep a history of the URL's and work with them. You need to be able to create the action with the various action information that created the original link. We are using IBM's WebSphere Portal v4 for this site. Before we converted it to v4 we were running it on Portal 2.1 which was jetspeed 1. Mark Finkenhagen 724-0316
>>> [EMAIL PROTECTED] 9/2/2004 11:38:06 PM >>> Hello Jaq, allow me clarify a litte more ... Users will not have the ability to customise portlets on our web site. All users will be considered "anonymous" without any customisation priviledges. We would define a bread crumb navigation portlet that is displayed on each page, hence the navigation portlet would always be displayed. We would have a main (aka. home) page with category and sub-category pages. The bread crumb portlet would be used in conjunction with the main menu and side menu (when required). We are hoping to avoid an explicit site/structure file, instead deriving the page location from implicit or explicit meta data associated with PSML documents. We are still learning our way around Jetspeed 1, so any pointers are welcome. I am also curious as the correct keywords to use when describing this problem to others within this mail group and other portlet developers. Does bread crumb navigation have another more common or generalised name ? Tim.
