hi peter,
ASOs that have a (non-empty) constructor can be instantiated by
contributing to the ApplicationStateManager service. Please see
the thread for the source. if you contribute to this service you can
still use the @ApplicationState annotation.

maybe you missed the point here,
never mind the reason I use the _ prefix ..
the problem was with hibernate, not with tapestry

Hi Peter
1) I think the general opinion on this is that a service and an aso are
completely different animals. I can't think of a situation where I'd
ever want an aso to be a service (or vice versa), but that's just me. If
there is a way to do this, someone else will need to chime in.

Hi all,
Following on from a previous post on this subject I have some questions
on Tapestry 5 IoC:
1. How do you register an ASO as a service if you have to provide
arguments to the constructor (i.e. you cannot use @ApplicationState in
this case).
2. How do you retrieve a service object th

Lewis Ship-ism. (actually, I have it too from my NeXTSTEP days.)
It's not mandatory, however, so on your persistent objects, you could
use the typical pattern and annotate your properties, if that's how
you want to do it.
Tapestry-ioc already calls the "something" a configuration:
http://tapestry.apache.org/tapestry5/tapestry-ioc/configuration.html
so Howard's "configure" naming suggestion looks even better.
(This has been discussed previously in this list.)

There are at least 2 ways to do this.
If you follow Serge's suggestion of a context, you need to use

The alternative is to use an ActionLink instead of PageLink i
I can't check the code right now, but pageAttached may be too early.
Try either onActivate or setupRender.

IOC helps your code being more modular and less dependable,
you make your DAO class so it receives Session via constructor,
you can use your DAO class in any project easily.
in a tapestry app you add your DAO as service,
an later on inject it where needed. IOC gives
your DAO class the Session and

You can define a variable as a field of your component class.
However, it won't be visible without your providing a getter and setter.
Example:
${user.name}
Java code:
public class MyPage {
@Inject
private UserDatabase _database;
private User _user;
public UserDatabase getDataba
There's a bit of magic going on. Most of your parameters will be null
except when you have a break point inside code during the rendering of the
component. Further, some of your code will have to read a value from a
parameter field for the field to get filled in.
Basically, the first time you ha

I would avoid the use of static maps for tracking the radio groups. In
addition, static will be shared between threads, so you have code that will
likely break in production.
In my book, static should always be stateless.

I can see what you mean, though it is quite common to use the index inside
the page class too. T5 keeps things simple to cover the most common cases.
You can create your own components if you don't like the default ones.
It would be interesting to see an alternative if you write one.

The value and index have to go somewhere. Why not in your page class?
