Hi,
Sorry, but I don't get exactly what to do here. As I understand it you're
advising me to store a separate map of Pages in the Session and then lookup
the previous Page there? Otherwise I wouldn't see how to implement the
YourSession.get().getPage() method as I still can't get to the PageMap's
size to use that to calculate the previous PageEntry's id. I'm probably
totally missing something here :)
Thanks,
Ivo

What i would do is a bit different.
You want a stack of the last rendered pages?
if you have a common BasePage then override:
protected void onBeforeRender()
in that method you take your session and add a object that stores the page
id and the current version number entry.
YourSession.get().addPageEntry(getPageMapName(), getNumericId(),
getCurrentPageVersion());
then if you want go back:
YourSession.get().getPage(-1)
-1 (is the previous page) -2 skip 2
in that method you can get the page then:
return PageMap.forName(pagemapname).get(pageid,versionid)
