I don't think models have to be implementation details. Sometimes that
makes sense, and in that case I usually like to embed the model class
in the component itself. But lots of other times, you can make the
model so that it can easily be reused by other components, possibly at
the same time. This is especially true for master detail relations
etc, something you can perfectly model with interdependent models.

One of the main reasons for us wanting to apply generics in Wicket 2.0
is to have strongly typed models. In Wicket 2.0, components can force
that they only accept models of a certain type (e.g. IModelPerson)
so that you can have the same type of strong typing you have when
passing pojos, but still hiding where the pojo comes from (or when).
So in Wicket 2.0 a development approach where you pass models a lot
makes even more sense.

That's just my 2c of course :)

Eelco


 Currently I use models to hold, attach  detach my persistent objects.
 About using IModels in constructors, I've mostly do it to be able to
 unit test my pages easier. But inside my application code, I prefer
 other components *not* to see or be aware of each other's internal
 models. That said, I prefer 'new PersonProfilePage(id,person)' instead
 of 'new PersonProfilePage(id,profileModel)'. I would like to hear
 comments on this, since I'm not sure everybody agrees.

Re: [Wicket-user] ListView#accept() proposal

2006-07-18 Thread Johan Compagner

But then you need to pre filter the list. Because what would size() return??But going with something out of the repeater package would be better.But then still you need to filter up front because all those Repeaters do want to know the total size?
And filtering on demand doesn't work then.johanOn 7/18/06, Igor Vaynberg [EMAIL PROTECTED]

ie:


add( new ListView( list, myList ) ) {

Would this be trivial to add to the ListView component?

Yes in 1.2 there is a the problem that it doesn't go through setObject it does

This will be fixed in 2.0. Because we did need to change some internal things

Hi 



Starting this over again, trying to explain more clearly what im doing
here.



I've created a AbstractModel that pretty much works as property model,
only difference are that the setObject sets the object and does a little bit
more. My model is attached to the wicket.extensions.markup.html.form.palette as
the model representing user choices. The palette component consists of two
listboxes and some buttons to move the selection, it moves the selection by
_javascript_ so I have a submit button in my form aswell.



My issue is that it seems as the models setObject are only called in the
constructor, or when I explicitly call it? But I can clearly see that the
palette gets updated correctly even if I switch pages.



Regards Nino

yes you are right.But in 1.2 this couldn't be done because of some code that was sitting in the way (modelChanging/changed double called and so on)in 2.0 we pretty much have fixed that part i believe. now. Have to look at it further.

I see the following pros

Pro setObject:

Allows the user to
implement logic into the model If so desired


 Special conversions to satishfy wicket components needs, for
 example, wicket component needs one list but you have three, so join them
 in the get operator and split them in the set 
 Logic, etc disable other components, notify …
 Hold the standard implicitly directed by having a set object method
 Feels the right way

Con setObject:


 Performance could be slightly improved?




I do think that that
using setObject on the model is something that always should be done; it
creates a lot of flexibility and why have setObject if not to use it, if not it
will only cause confusion.

components whose model is
backed by a collection do not always call setobject() because they work on the
collection directly so there is no need to call

Collection c=model.getObject();
c.clear();
//refill c
model.setObject(c); == NOOP

and also in wicket there is a guard

component.setObject(c) {
 if (c.equals(model.getobject()) {
 //noop
 } else { //clone for version tracking; model.setObject (c); }
}

the above saves on unnecessary cloning.

just a few things to be aware of, whether or not we should call setobject()
anyways is still up for discussion.

i kinda think we should even though sometimes the objects are the same.

Whenever a (form)component has to update it's modelcontents. Or if
you call setObject explicitly of course :() Typically, a component
update is done by Form, which visits all it's children and calls 
updateModel on them.

[Wicket-user] java.io.NotSerializableException on my session object

2006-07-18 Thread Steve Moitozo

I just changed the log4j log level for wicket to DEBUG and now my
application craps out with the following error:

Internal error cloning object. Make sure all dependent objects implement
Serializable. Class: mystuff.wicketapp.MyWebSession

Am I to assume that the entire hierarchy of class properties contained
within MyWebSession must implement Serializable? If so can you offer any
alternatives?

Why does my app still work when the log level is set higher? I guess the
real question is does it really work? I haven't tested clustering and
state replication. I would assume that the above error would cause state
replication to fail. True?

Re: [Wicket-user] Wicket Hibernate Application Transactions

2006-07-18 Thread Nathan Hamblen

Agreed. I don't think there's anything here that needs fixing. I was
just saying that if Iman or anyone else wants to experiment with
extended Hibernate sessions, I think that would be cool. (Reattaching
orphaned Hibernate objects is not a road I would want to go down.)

In the mean time our system of loading rows from the database on each
request cycle is totally ligit and no different from practically every
DB+HTTP app out there.

Re: [Wicket-user] java.io.NotSerializableException on my session object

2006-07-18 Thread Steve Moitozo

Thanks for the quick response. Do you know if there's a way to tell Java
 which parts of an object are vital during serialization and which can
be ignored. I'm thinking about how Detachable Models work.

Am I correct in assuming that if I do not correct this my app will
continue to work in a single JVM environment but it will probably not
work in a clustered environment?

Re: [Wicket-user] java.io.NotSerializableException on my session object

There is a DEBUG level logger in wicket.protocol.http.HttpSessionStore
that tries to serialize any attribute that is set. The development
version - soon 1.2.1 - has a fix so that it doesn't depend on the log
level, but instead on an application setting:

if (Application.get().getDebugSettings().getSerializeSessionAttributes())
{
String valueTypeName = (value != null ? value.getClass().getName() : 
null);
try
{
final ByteArrayOutputStream out = new ByteArrayOutputStream();
new ObjectOutputStream(out).writeObject(value);
log.debug(Stored attribute  + name + {  + valueTypeName + 
} with size: 
+ Bytes.bytes(out.size()));
}
catch (Exception e)
{
throw new WicketRuntimeException(
Internal error cloning object. Make sure all 
dependent objects
implement Serializable. Class: 
+ valueTypeName, e);
}
}


The reason we deliver that functionality is to help you ensure you
application can function properly in a cluster, using session
replication. There are many strategies however, including a different
approach than normal serializing, but serializing is the default, and
is something you should use when you use a backing httpsession
(Wicket's default) anyway.

Anything that may end up in the session store, components (and their
state), models, etc, should be serializable. If you want to pursue a
different strategy, implement an ISessionStore that does this.

Hope this helps,

Eelco

yep, the transient keyword. Transient fields will not be serialized

Correct, if you use the default serialization mechanism. Fix is easy
usually. Just let those classes implement Serializable.

Re: [Wicket-user] java.io.NotSerializableException on my session object

2006-07-18 Thread Steve Moitozo

 not really sure what you mean or why you would have to do that. what is the
 usecase for having something that is not serializable in session?

As I trace this issue through my code it's becoming apparent that since
pages are added to the session any properties that is in a page that
isn't serializable causes the error. So it's not that I want to store
non-serializable things in the session necessarily. Many of my pages use
third-party libraries that are not serializable and these seem to cause
the issue.

I'll admit I'm a new comer so I may be missing something or violating a
Wicket principle as I build out my app.

 the debug feature serializes immediately so you get the error now
 instead of whenever the servlet container tries to replicate your session
 for you - at which point you will get a very similar error.

Thank you for this!

Re: [Wicket-user] java.io.NotSerializableException on my session object

well, now that you are aware of this going should get better.in case you are storing beans from other framework that are not serializable i really dont see an easy way. the creators of those projects should make sure their objects are serializable. the only thing i see that you can do is to create a serializable bean yourself that has the necessary logic to translate to and from the other bean. or subclass it, override writeReplace/readReplace and do the same thing.
in case you are talking about stateless objects from other frameworks you have a lot more options:use a pure getteruse a null-check-getter in conjunection with a transient field if lookups are expensive and you want to cache them for a while
use a wicket-spring type of proxy that is serializable and knows how to look up the dependency - kinda like a middleman between your dependency and serialization-Igor

[Wicket-user] set static values on DropDownChoice

This seems like a lame question but I'm struggling again w/ the
DropDownChoice control (using 1.2).

I simply want to set static values to a DropDownChoice control so they
can be drawn out later in the form's input class when it's submitted.

I thought I had done this before but can't find that I have - how can
I set, say, a Map of name/value pairs of Strings?

In this case I'm not providing a ListT of values to the dropdown but
rather a MapString, String of static values - unless of course
there's an easier way.

This control still feels cumbersome to work worthperhaps it's just me?

Thanks!

Re: [Wicket-user] More examples of sorting?

yep, you have to code your daos with paging and sorting in mind, it cannot be slapped on as an afterthought.let me give you some cluessee the attached QueryParam class, all my finder dao methods take it so that they can page/sort accordingly.

Re: [Wicket-user] More examples of sorting?

Well, I don't have DAOs in this particular project - it's an EJB3
project where I'm simply using SLSBs as DAOsso I have the
EntityManager to work from and I should be able to bring the two
together to facilitate this...

This may be easier than I thought

Re: [Wicket-user] More examples of sorting?

then the only semidifficult part is the sorting - you need to come up with some utils that append the sort for you.as far as paging it would translate directly tosession.setFirstResult(queryparam.getFirst()).setMaxResults(
queryparam.getCount());-IgorOn 7/18/06, Vincent Jenks [EMAIL PROTECTED] wrote:

Re: [Wicket-user] More examples of sorting?

Wow...ok...I'm making a total disaster of this.  I can't help but
think there's an easier way. :(

I've got this method in what we could call a dao:

public ListIncident getFiltered(int first, int count, String orderBy)
{
String query = select i from Incident i order by :orderBy;

Query q = this.em.createQuery(query);
q.setParameter(orderBy, orderBy);

q.setFirstResult(first);
q.setMaxResults(count);

return q.getResultList();
}

And I've got started what might someday become a provider class:

public class IncidentsProvider
extends SortableDataProvider
implements IDetachable
{
private transient ListIncident incidents;

/**
 * default ctor
 */
public IncidentsProvider(Integer first, Integer count, String orderBy)
{
this.incidents = myDao.getFiltered(first, count, orderBy);

setSort(openDate, true);
}

public Iterator iterator(int first, int count)
{
return this.incidents.listIterator(first); // - what do do?
}

public int size()
{
return this.incidents.size();
}

public IModel model(Object object)
{
return new Model((Serializable)object);
}

public void detach()
{
this.incidents = null;
}
}

As you can see, I'm trying to marry my provider to my DAO as closely
as possible...I'm not worried about elegance and cleanliness right now
- just trying to take it one step at a time and get it *working*.

I can make some sort of 'if asc then make desc' and vice/versa afterward

Sorry, it's been a long day...maybe I need a breaktwo or three
weeks ought to do it.
