Hi,
Please create a ticket with a quickstart.
With a patch would be awesome!

However, I'm experiencing problems when using generic beans with Wicket's

I basically have following situation, two concrete dao's that implement a
generic typed interface dao.:
class Product{}
class Car extends Product{}
class Phone extends Product{}
interface ProductDaoT extends Product {}
class CarProductDao implements ProductDaoCar {}
class PhoneProductDao implements ProductDaoPhone {}
class ProductModelT extends Product extends LoadableDetachableModelT {

}
class ProductPage extends WebPage {
...
ProductModelCarProduct model = new ProductModelCarProduct(product);
...
}
This will result in the following error:

Re: What is the proper way to start a secondary process in Wicket 6
Dear All,
With the invaluable help of Martin Grigorov, I have summarized the
discussion on this thread on a small Wicket in Action article [1]. The
complete sample project can be found at [2].

Many thanks! I will try to have a look today at the PR and see if I find
the time to write the blogs article during this week.
Thanks again!

Hi Ernesto,
See https://github.com/reiern70/antilia-bits/pull/1
I've moved the code that exports the Application thread local to
TasksRunnable. This way it is possible to export the Session too.
The code looks good (after removing all annoying whitespaces :-) ). Now it
needs some explanation (i.e. blog article) ;-)

Ernesto,
That’s kind of what I ended up doing except with a different
ThreadPoolExecutor implementation.
ExecutorService executorService = new ScheduledThreadPoolExecutor(20)
{
@Override
protected void beforeExecute(Thread t, Runnable r) {
ThreadContext.setApplication(MyApplication.this);
}
@Override
protected void afterExecute(Runnable r, Throwable t) {
ThreadContext.detach();
}
};
No particular reason why I picked ScheduledThreadPoolExecutor other
than
it looked a little easier to use. I need to look more into the
different
types of Thread pools and such.
I used:
ThreadContext.detach();
instead of:
ThreadContext.setApplication(null);

Something like:

But there is no more Application#set(app) and Application#unset()

Wicket 6. Does Wicket 6 have some built in way of creating
secondary
processes, maybe an internal thread pool that can be set-up ?

Ernesto, great job putting all that code together so quickly. I
cloned
your project and cherry picked out the code that I needed, I don’t
need all
the process progress code you have. I don’t really care what the
process
progress is or even if it completes ok, just don’t want it
holding up
my
response.
I ended up using your ExecutionBridge, TasksRunnable, and ITask
classes
and interfaces. But I still don’t know where and how to inject my
service
into this new task/thread or ExecutionBridge without getting this
exception:
Exception in thread pool-1-thread-1
org.apache.wicket.WicketRuntimeException: There is no application
attached
to current thread pool-1-thread-1
Do I need to get the application attached to my new threads
somehow
so
I
can use my injected service, and if so, how do I do that ?

Re: DebugBar reports strange sizes
I'm having trouble fully understanding Wicket's serialization.
I understand that if I declare a final object outside of an anonymous inner
class and then use it from within that anonymous inner class, the compiler
will ass a member variable to the anonymous inner class which gets
serialized.
final Object outer = /a 10K entity/;
add(new Label(label, new LoadableDetachableModel() {
@Override
protected Object load() {
return outer;
}
}));
However if the containing component / page has a large Model
setDefaultModel(Model.of(/a 50K entity/));
DebugBar Inspector reports that the Label takes up 66.5K (including the 6.1K
debugbar).
Does this mean that all anonymous inner classes, declared within a component
with such a model, will serialize a copy of the container? This seems to be
what the sizes reported by the DebugBar suggests...
(I'm aware of the correct usage of LDMs etc. I'd just like to understand the
consequences of the various anti-patterns)
Thanks,
CN

Hi,

Actually the inner class has a reference to the complete outer/normal class.

Does this mean that all anonymous inner classes, declared within a

Yes and No.
Java serialization will serialize the referred container *once*. All inner
classes will serialize just a pointer to the container.
what the sizes reported by the DebugBar suggests...
(I'm aware of the correct usage of LDMs etc. I'd just like to understand
the
consequences of the various anti-patterns)
Calculating the size of an object in Java is very tricky. It is a best
effort, not exact.
