Another option for remembering where you have come from is to tell the page
explicitly.
In Member have @Persist private Link _lastPageLink;
In Home/Other have @InjectPage private Member _memberPage;
You can use an action link handler to go to the page
protected Link getGotoMemberLink() {
Object[] context = <your memberPage context>;
return _resources.createActionLink("gotoMember", false, context);
}
protected Object onGotoMember(Object[] context) {
Object[] homeContext = <whatever context you want for your home link>
_memberPage.setLastPageLink(_resources.createPageLink("home", false,
homeContext ));
_memberPage.onActivate(context); // presumably you are using
onpassivate in Member to properly remember this context
return _memberPage;
}
in Home/Other template <a href="${gotoMemberLink}">Member</a>
This was from memory, so I may have messed up some specifics, but the
concept works.
I haven't investigated issues such as having the same session active in two
browsers (I assume the persisted _lastPageLink would be shared.)
Also, you might be worried about using the action link method if your page
does heavy initialization (loading stuff from a db for instance) in the
activate method, I've been moving it into setupRender.
I have the persisted _lastPageLink in a base class so that I can use it in
all my pages. You could probably make the gotoPage action and
getGotoPageLink generic and put it in the base class as well.
