ok.
But, looking at the Javadoc, this is what I see:
In AbstractBehavior:
/**
* Called when a component that has this behavior coupled was rendered.
*
* @param component
*the component that has this behavior coupled
*/
public void onRendered(Component
No no bug just java doc isnt clear enough i guess, but it is not
really wrong.. What is after render? Both are true, both are called
after the component is rendered only one a bit later then the other. I
guess the javadoc of the component should state that this is after the
page is rendered

Hi,
I was wondering whether it was possible to implement pooling of stateless
pages? Possibly using a custom PageMap implementation?
Although newer JVM's are good at performing GC, pooling is a reasonable
additional technique to use for achieving that extra bit of scalability.
If anyone has
Hi,
first of all, I don't really think it's worth pooling pages. I can't
imagine that page instance creation would have that much overhead.
Also stateless pages doesn't mean they don't contain any state. The
page is stateless because it's not kept between requests, but during
request there's lot
For stateless pages??
The whole point of stateless is that they arent kept in the session/memory.
And pooling pages is not really what you want any way, you can only
pool then for a single user/sessiion so you would have a pool for
every session.
And when do you decide to return a pooled page?
For stateless pages??

Johan,
Although the pages are stateless, they can still be pooled, and
re-initialised (their state cleared out) between requests.
This is indeed what many java servlet containers do with stateless Servlets.
It is also the a technique used by Tapestry 5 to achieve greater
scalability.
Rgs,
The overhead incurred would of course depend on the number or requests the
app was receiving, the amount of available memory and the efficiency of the
chosen GC algorithm. I agree that object creation and collection is
relatively efficient these days, but pooling still makes sense where it can
We are not tapestry 5. :D
Seriously: page pooling is not good for scalabity. You need to apply
locks to prevent multiple threads to access the same instance, etc.
There is a whole lot of additional stuff you need to make this work,
adding complexity for little or quite possibly no gain at all.
I would agree it's not always going to give much mileage. Given that there
is no heavy weight initialization going on with pages I would tend to agree.
The JVM should be able to cope with many 10's of thousands of objects
created destroyed per sec, more or less system dependent, so long as
I agree with Johan. Stateless in Wicket sense means that we don't keep
the page in memory but recreate it from scratch. This means that we
don't roll back state. Pooling requires us (the framework or the
users) to rollback any state that was accumulated during rendering.
This is really not an
If you were to add in pooling, you'd have to either provide a new hook
(new lifecycle method) or a warning to the user (as you mentioned)
that they have to rollback the state themselves after rendering using
onAfterRender() or something.

Accessing pages in other threads then the request thread is very bad idea.
Because http session object shouldnt be touched between requests, you
have no idea what the container does with your page/session. Store it
on disc, replicate it to other nodes.

It may even re-use the actual session object instance for another
