[T5] creating event links without the page activation context being encoded into the URL

[Jochen Kemnade <jo...@web.de>]

Hello,

I've got a problem with creating "stateless" event links. I've got a page, which has an activation context. On the page, there's a component, that displays images. These images are rendered by a service, which I have injected into the component. In the component, I use an event link and a handler method, that uses a method of the service to have the images created. The problem I run into is, that the created event links get the page activation context encoded as t:ac URL parameter. This information is needed neither by the component nor by the service, but it prevents the browser from caching the images. Can I somehow create event links without this parameter?

Regards,
Jochen

What value are you passing to the context field of
LinkFactory.createComponentEventLink()? AFAIK, Tapestry always adds
the current activation context to any links, unless you specify an
activation context yourself. Try createComponentEventLink(Page page,
String nestedId, String eventType, boolean forForm, new Object[0]).
