Tapestry 2.3/ pageDetached() never called?
Hi,
Quick question on component property cleanup. I have a component that
derives an instance variable from a cookie. The component contains a
stateless form that sets values on the instance variable, and inturn sets it
on another page. The problem that is occuring is that the instance
variables on the component are never detached after the action method is
invoked.
There is a detach() method in the Page's .java file. The component's .java
file implements PageDetachListener, and contains a pageDetached() method
which seems to never be invoked.
I'm I missing a step here? Is there something else I need to do on the
Page side to ensure that the component detaches it's variables?
Thanks in advance,
Eric
PS. The application is stateless....though, I'm not sure that has anything
to do with what's happening.

There is a addPageDetachListener(PageDetachListener) in AbstractPage
that you can call I guess.

Howard,

Thanks, but how would a component register itself with a page as a listener?
I just need a little more of a hint.
I implement a finishLoad() method in my component, correct? What do I do
after that? Nothing is jumping out at me.
public void finishLoad(IRequestCycle cycle, IPageLoader loader,
ComponentSpecification specification)
throws PageLoaderException {
super.finishLoad(cycle, loader, specification);
}
Thanks,

In 2.3 you have to have your component register itself with the page as a listener, usually from
finishLoad().
In 3.0, the component automatically registers itself (if it implements the right interface).
