Hi.
I'd like to notify all of the visible presenters
before and after a request is handled.
Conceptually, it would be something like
this:
-------
MySession>>handleRequest:
aRequest
"This is not code, only an intention of what I would like to do" | answer |
self root visiblePresentersDo: [:each | each
beforeRequestHandling].
answer := super handleRequest:
aRequest.
self root visiblePresentersDo: [:each | each
afterRequestHandling].
^answer
-------
the reason to do that is that I have some
WAComponents of mine which have to lock a resource during the rendering and the
callbacks handling. Right now, I'm locking and releasing the resource every time
I need to (for instance, in the #renderContentOn: method, but also inside every
callback), but I would prefer each component to do it automatically during each
request, so I can fogert about it.
The question is: can something like that be done (I
mean, would it work for scriptacolous callbacks too and that sort of
things) ? And if it is, where and how should I do it ?
thanks in advance

You might want to override #renderContentOn: and #processChildCallback: within your root component, or within a decoration that you add around your root component.

Hi Martin,
firstly I expect you found a way to achieve your requeriments. Secondly, a word of caution about locking. Have you really need to lock in render time? That could slow down your render and, which is worst, will create a point of contention for the service of your application. Maybe you find a way to do the lock thing in a non syncronous process preventing your render of being a guaranteed bottleneck. cheers, Sebastian ________________________________ De: [hidden email] [mailto:[hidden email]] En nombre de Martin Rubi Enviado el: MiƩrcoles, 16 de Abril de 2008 15:09 Para: [hidden email] Asunto: [Seaside] notifying all the visible components before and after arequest is received Hi.
