Josh,
Yeah that looks like it would do it, working much like what proposed
with pagelinks. Given a choice I would use the pagelink based way
because architecturally it works the same (news page collects the id via
context), but using pagelinks reduces the round-trips and the need to
deal with even
Here's an app that does what I believe is trying to be done:
// Page
public class News {
@Property
private Integer _newsId;
public void onActivate(Integer newsId) {
_newsId = newsId;
}
public Integer onPassivate() {
r
I do hope we've missed a simpler way, but I don't think it's surfaced
yet. Regarding parameters, how would that address the issue? NewsQuote
displays a collection of items as links that represent selectable items
(expressed as links). The action must be taken based on the user's
selection, so a com

this the last of it
4) In our embedding page class, News, we have an event handler to be
notified of the selection by handling the "viewitem" event:
void onViewitem(long id) {
this.currentItem = newsSource.getItemById(id);
logger.info("got " + this.currentItem.getTitle

Hello,
You can define the scope of each service...you can set that
particular
service to be tied to only one session.

This is not what @Retain is for. If you use it, the value won't be
cleared out at the end of the request.

How can any component embedded within this page access this variable?
