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

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

Hi there,
finally I put together a minimalistic test to proof the idea.
1. I have a simple component, named SetRequestParameter, its purpose is to
receive something from an actionlink (it is on its template) and set that
value in a per-request way.
1.1 the template for this component

Hi,
thx for the info! Another idea... is there a HttpRequest like object
available to components and pages? If it were, then setting a request
attribute would be ok for me. Anyway the per-request service is similar to
this, so it will be ok for me.
thx again

Hi there,
the service approach (as I expected) is session-agnostic (and is
page-independent so concurrent users would interfere badly), therefore is
not ok.
I will now try the Environment approach... if that is session-aware :)

Janos,
Without code or a description of your actual goal, I'm finding your
situation too hypothetical to really digest. The one thing I can point
out is what you said about wanting a component to set a property in the
page. If you want to do that, then you have to know the class of the
page and so
Hi Chris,
I thought of pages as "contexts" for the components embedded within them.
So, in one event handler of a component I would like to set some property or
another (in the page object), and the other components in the page, which
are also able to access this property may change their appearan
Janos,
I'm having a hard time understanding a case that a component should know
in which page it is embedded, so my suggestion probably wasn't a good
one. Activation contexts aren't meant for components but for pages - you
should be using component parameters to configure them, and if it's a

hi janos,
there are several possibilities:
1) declare a component parameter and pass in the variable
2) put it in a ASO and inject the ASO in all your components (using
