Yes, page labels work fine. I use page labels as they already identify
the portal state through urls and I only have to "attach" the
CopletLinkEvent when persisting links/urls - so I thought.
Thanks

Have you configured your application to actually use page labels? By

Hi all,
I am trying to implement persistent links within an application coplet
of the portal. By default the internal links of external applications
are dynamically converted to "?cocoon-portal-event=xx" parameters at
runtime. So a particular page of an external application is not easily
bookmarkable or to be incorporated in search results, etc. So to have
a search crawler be able to index these pages, these links have to be
globally valid, identifyable and have to survive Tomcat restarts. In
short, they have to be persistent.
I found it would be easiest to base the implementation on the
PageLabelEventConverter.
As a test I tried to manually create a CopletLinkEvent within the
start Method (initialize() wouldn't work because this code accesses
the ProfileManager) to simulate recreating these Links from a
persistent store:
public void start() {
String label = this.labelManager.setCurrentLabel();
try {
PortalService portalService =
(PortalService)this.manager.lookup(PortalService.ROLE);
PortalComponentManager componentManager =
portalService.getComponentManager();
ProfileManager profileManager =
componentManager.getProfileManager();
if (this.eventList.size() == 0) {
CopletInstanceData cid =
profileManager.getCopletInstanceData( "Google-1" );
if (cid != null) {
cid.setAttribute("cookie", null);
cid.setAttribute("documentbase",
"http://www.google.de/";);
Event persistentEevent = new CopletLinkEvent(cid,
"/intl/de/about.html");
this.eventList.add(persistentEevent);
}
}
} catch (ServiceException se) {
this.getLogger().error("Error getting " + PortalService.ROLE +
": ", se);
}
}
The event gets correctly endoded into the pages. Even decoding seems
to work correctly, however clicking this link simply reloads the
current page.
Any idea what might go wrong is much appreciated. The complete Code of
PageLabelPersistentEventConverter is below.
Thanks
