When wicket tries to initModel it searches parent components for their model, but it doesn't use getModel, it uses getModelImpl, which does none of initModel magic.

Property Model Issue
Hi guys,
I'm having an issue with property models.
I have a DataView running over a number of Post objects. The Post object
has a property named product with appropriate getter/setter.
new DataViewPost(posts, provider) {
protected void populateItem(final ItemPost item) {
item.setModel(CompoundPropertyModel.of(item.getModel()));
item.add(new ProductPanel(product));
}
}
The issue is within ProductPanel. It has a number of labels, each only
specifying a name (no model). In my initModel() I am creating a
CompoundPropertyModel around super.initModel(). I was expecting it to
pull these properties from the model object of my ProductPanel.
public class ProductPanel extends GenericPanelProduct {
public ProductPanel(final String id) {
add(new Label(name));
add(new Label(condition));
}
protected IModel? initModel() {
return CompoundPropertyModel.of(super.initModel());
}
}
But I get this error: org.apache.wicket.WicketRuntimeException: No get
method defined for class: class com.cellcycleusa.domain.Post expression:
name.
Seems that it's trying to access the Post object from the DataView to
pull the property from, not the model object of the ProductPanel itself.
Now the really funny part is that if I just add this to ProductPanel,
everything works fine:
protected void onBeforeRender() {
getModel();
super.onBeforeRender();
}
Or if I specify the model objects for the labels within ProductPanel
like this:
new Label(name, new ComponentPropertyModelString(name))
That works as well.
What am I doing wrong?

Hi Sam,
I think your use of Item#setModel() and Component#initModel() are
unconventional. Try:
Hi Dan,
Yes I never really liked my item.setModel() technique, just didn't seem
right to me but I've seen it in more than one tutorial so I figured it
was the way it was done. I actually moved the compounding part over the
newItem method in dataview just now though, seems cleaner.
populateItem(ItemPost item) {
item.add(new ProductPanel(product, item.getModel());
}
ProductPanel(String id, IModelProduct model) {
super(id, CompoundPropertyModel.of(model));
add(new Label(name));
add(new Label(condition));
}
I'm sure this would work, just wondering if there's a better way to do
this? Is it good practice to manipulate the model in the constructor
like that? Doesn't seem right to me as the model may need to change
(maybe via ajax?). I try to never mess with my models like that outside
of the rendering phase. I've been toying with wicket occasionally for
over a year now, but never gone this far with it so I'm still learning
how it all works.
I would if at all possible like to retain the ability to create a new
ProductPanel without specifying the model in the constructor. This seems
to be the way things are usually done in Wicket so I figured there must
be a better way.
Product is a property of post so I'd be specifying it in two different
places, and again if I wanted to add any more composited components
under ProductPanel.
I've corrected your code to reflect this (I just got your next message).
populateItem(ItemPost item) {
item.add(new ProductPanel(product, new
PropertyModelProduct(item.getModel(), product));
}
I was using the compoundpropertymodel to avoid specifying the product
property manually as is done above, but that part is working for me with
no issues, it's just inside ProductPanel that I'm having problems.
It's not that I'm really that lazy, just an issue of best practice for
me.

If you have lots of dynamic stuff you can use a texttemplate to interpolate
your variables with it works really smooth, heres an example:
...
HashMap variables = new HashMap();
variables.put(alert, helloworld);
TextTemplate textTemplate=new TextTemplate();
textTemplate.interpolate(variables);
String js= textTemplate.asString();
…
corrosponding java script, notice the template signature ${…}
alert(${alert});
So above code will produce a javascript string ‘alert(“hello world”)’ very
useful.
Thats in the first link I showed you; helps you put variables in
whatever markup you want. Am sure there are other approaches also, but have
a look before you think its not meant for you.

getClientModel gets an instance of EntityModel which contains a
reference to a repository and an id. The repository has a reference to
the hibernate SessionFactory.

If I understand correctly, getClientModelObject() will need a

Is that a problem?

It's just a billing system. The problem comes up now in very
simple use
cases.
Currently all we're doing is trying to load a collection with a
list of
Order domain objects from the Client domain object.
final SortableDataProviderOrder provider = new
RepositoryDataProviderOrder(getOrderRepository()) {
@Override
protected ListOrder load() {
return new
ArrayListOrder(getClientModelObject().getOrders());

Generics for datatable columns
This is a stupid minor thing but I was wondering. If I have a datatable of SubClass objects, shouldn't a I be able to add an IColumnSuperClass to the list of columns? Not very often used, but could be useful occasionally like for inheritance with domain entities. Couldn't hurt to implement this right (just add a generics wildcard)? - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Eg., if you change the country from Australia to USA then the state/zone drop down is populated with the US states. I was thinking of creating an interface for the data so that a generic world wide address form could be written to the interface but the implementation of the interface could be tailored to the way an individual app stores it's world data. -Original Message- From: Per Lundholm [mailto:per.lundh...@gmail.com] Sent: Friday, 29 January 2010 8:26 AM To: users@wicket.apache.org Subject: Re: functional testing We write tests first and use Wicket's built-in testing.

contributing components
I sent an email to this list the other day about releasing my wicket component toolkit. Anybody know how to go about this? I have some pretty interesting stuff, like a BeanPanel that displays a bean's properties in a nice looking key:value format, and another one that allows you to upload a file, but is abstracted so you can upload from a file on the local computer or from a web URL. My most innovative one accepts a list of files as input, and automatically generates zip/tar.gz/tar.bz2 archive downloads. I'm sure these will come in useful to many.

Generics
I've noticed in some places where generics wildcards may be useful that they are not used. For example, in IColumn.

Releasing wicket library
In the course of developing my first wicket web application, I've wound up with quite a few reusable wicket components, validators, and other utilities. I think things like a LinkPanel, EmailLink, etc etc should be available, after all wicket is all about reusability. I'm packaging and releasing them on sourceforge. If anyone's interested, check it out. Most of the stuff is stable and works, but it's not carefully tested or ready for release, but I went ahead and put it on sourceforge so anyone interested can use it or help out. This is the first upload, I'm currently adding comments and cleaning some stuff up. svn co https://swicket.svn.sourceforge.net/svnroot/swicket swicket It depends on jclib, universal java toolkit (very very useful). jclib in turn depends on common-collections15, commons-lang and a couple others.

As you can see it does not contain a line with the target response page but a

So you need to add a line that contains the 'name' of the anonymous class to

TextArea with list of strings.

It works, but when it is an invalid value, instead of a nice error

IConverter I am using.

While developing if you hot-redeploy often, you might also want to do a
check in load() like:
if (this.whateverService == null)
InjectorHolder.getInjector().inject(this);

Well, somewhere you'll need that logic what class is loaded by which
repo - you could of course do it in a more generic way using factories
or a kind of a mapper or whatever...
Since we only have around 10 classes, this is easy.
If you use hibernate, you can have it for free since you can instruct
hibernate to load the instance given the class and the id, for example:
T entity = entityManager.find(entityClass, id);

in load(), we have the code to load every possible entity in our

T entity;

entity = userService.load(...);

One more question about serializing objects.

Re: another serialization question
The value objects are not simple attributes of an entity. Let me explain what they do (a little simplified but the fundamentals are there). We have a research module that performs pricing research. ResearchItem CellPhoneResearchItem IPodResearchItem LaptopResearchItem Etc Since the identity of these research items is defined solely by their attributes they are implemented as value objects. I know this is different from your everyday value object (eg Address) Does this sound like maybe a problem that should be addressed in the domain model? Value objects were chosen since it makes it much easier in many other areas to just create a new research item, rather than call repositories to load old ones (impossible in some places). No point in loading something you know all the attributes of. The only way to get them reliably is to call ResearchItemGenerationService.generateResearchItems() -Original Message- From: James Carman jcar...@carmanconsulting.com Date: Wed, 11 Nov 2009 00:10:15 To: users@wicket.apache.org Subject: Re: another serialization question Can you go through the entity to get to these objects?

serialization
Hi. Wondering if someone can help me with a serialization problem I'm
having.
To start off, the domain model in this application does not use
serializable domain objects (the project is using db4o, which does not
play well with serialized objects).
I have a page with this code:
IModelValueObject valueObjectList = new
LoadableDetachableModelValueObject() {
protected void load() {
return getVOGenerator().generateVOs();
}
}
add(new ListViewValueObject(vos, valueObjectList) {
...
});
I'm getting this error:
org.apache.wicket.util.io.SerializableChecker
$WicketNotSerializableException: Unable to serialize
class: ...ValueObject
How do I get around this?

Re: serialization
sorry sorry i made a mistake in the populateItem
these is a nested listview
populateItem(ListItemValueObject item) {
final ValueObject valueObject = item.getModelObject();
add(new ListViewOtherValueObject(child, getOthers()) {
populateItem(ListItemValueObject item) {
Money price =
getPricingService().calculatePrice(valueObject,
item.getModelObject())
}
}
}
Looks like the problem has to do with me accessing the valueObject
variable from inside the nested ListView. any clean way around this?
