Re: Page navigation links

[Frank W. Zammetti]

Presumably you would want such a construct to work regardless of what 
path a user took to get to a specific page (assuming there ARE multiple 
paths in your app, maybe there aren't).  So, if it was me, I'd be 
thinking a linked list stored in session.  Each page that is presented 
would append itself to the list.  Clicking a link would have to break 
the list at the point of the page that was clicked (i.e., if there are 
six pages in the nav trail and the user clicks the third, you basically 
want to discard the last three, which just means removing the link to 
the next element from the element of the page the user clicked).  You 
would of course have to add enough information to each element in the 
list as to allow your app to go to that page when clicked.  Might just 
be storing the Action path, might mean each element is really a HashMap 
with a bunch of information, you would have to decide.

I'm not sure something like this exists yet, I'd certainly think it does 
though.  If you have to roll your own, I suspect it wouldn't be too 
difficult using this approach (assuming I haven't glossed over something 
that makes it impossible or overly difficult of course!)

Hi all
 

Anybody got an example of how to implement a page navigation link for the
top of a page like so...
 

Home > MainFgorm > wizardpage1 > wizard page 2 

 

The last entry would be the name of the current page and would not be a
link. I'm thinking of a session object where the page inserts it's name
somehow so that if the page is re-used in different areas it puts it's link
in the correct place.
 

Just wondering how this can be achieved easily with struts and without
hardcoding the paths on each page. 

 

Thanks
