Re: Different root between upload folder and ContextRelativeResource
Hi, ContextRelativeResource looks for the resource in the web application context, i.e. in the folders next to WEB-INF. By using new File()/Folder() with relative path you create file relative to the current working directory. In Eclipse this is the folder that contains 'src/' folder. When deployed this depends on the used web container. Use : System.err.println(CWD: + new java.io.File(.).toAbsolutePath()); to see what it is exactly. In the other thread I suggested you to use ByteArrayResource instead. See http://wicketinaction.com/2011/07/wicket-1-5-mounting-resources/ for example.

Issue while adding Custom Validator to ListMultipleChoice component
Hi,
is it possible to add Custom Validator (implenting IValidatorT) for
ListMultipleChoice component?
when i'm trying to add validator to the the componnent using the below code,
final ListMultipleChoiceAttribute selectedFields = new
ListMultipleChoiceAttribute(selected,
new ListModelAttribute(new ArrayListAttribute()),
availableAttributesModel,
FIELD_RENDERER);
selectedFields.setOutputMarkupId(true);
s*electedFields.add(new SelectedAttributesValidator());*
i'm seeing the below compilation error for the above statement
*The method add(IValidator? super CollectionAttribute) in the type
FormComponentCollectionlt;Attribute is not applicable for the arguments
(SelectedAttributesValidator)*
Following is the Validator Class
=
public class SelectedAttributesValidator implements
IValidatorListMultipleChoicelt;Attribute
{
/**
*
*/
private static final long serialVersionUID = 1L;
/**
*
*/
public void validate(IValidatableListMultipleChoicelt;Attribute
validatable)
{
final ListMultipleChoiceAttribute selectedFields =
validatable.getValue();
if (CollectionUtils.isEmpty(selectedFields.getChoices()))
{
validatable.error(new
ValidationError().addMessageKey(attributesMustBeSelected));
}
}
}
the reason i'm going for Custom Validator is as i'm unable to get the value
from the getConvertedInput() as it is showing always empty, when the form
is loaded with default values. Not able to understand what could be the
problem.
can one please let me know, if there is any issue in the above code?
Thanks

The generic type of your validator should be:
public class SelectedAttributesValidator implements
IValidatorCollectionAttribute

Re: Wicket integration with Spring
With the 2nd approach you couple the application (in the role as service
mother) to all your calling components.
Coupling is a bad idea. It's hard to test in separation and almost
always you end in a hell of small single methods.
But if you inject your beans into the target component you can define
your required dependeny there were you use them.
Another cool approach in wicket is the event system in 1.5+. So you
throw events in child components and provide the
services in high ranking components (page, app ...)
Just my 2 ct.

I am making an application in which I want to integrate Wicket + Spring.
Application is a grocery store on which user comes and buy something. I know
there are two ways to do this.
1. Using the *annotation *aprroach. Wicket-Spring integration shows various
ways on how to inject Spring Beans into Wicket pages.
public class FormPage extends WebPage
{
@SpringBean
private IContact icontact;
...
Form form = new Form(contactForm,
new CompoundPropertyModel(contact))
{
private static final long serialVersionUID = 1L;
protected void onSubmit(Contact contact)
{
icontact.saveContact(contact);
}
};
2. The @SpringBean is of course valid and considered a best practice by
many. But there is also *another approach*, where your Wicket Application
has the services you need.
public class YourWicketApp extends WebApplication{
public static YourWicketApp get(){
return (YourWicketApp) Application.get();
}
private ServiceA serviceA;
// getter and setter for serviceA here
}
Now in your component, call
YourWicketApp.get().getServiceA();
I want to know which is the best way to integrate spring with wicket.
/However as far as I remember Wicket pages and components aren't managed by
Spring container so you cannot use @Transactional annotation on them (which
is a bad idea anyway - transactions belong to deeper levels)./ *Is this
statement valid?*

Re: CSS load order in 6.x
Many thanks for your help.
This is what I have done:
public class YUICalendarCssResourceReference extends CssResourceReference {
private static final long serialVersionUID = 1L;
public YUICalendarCssResourceReference() {
super(YUICalendarCssResourceReference.class, yui.css);
}
public Iterable? extends HeaderItem getDependencies() {
ListHeaderItem dependencies = new ArrayListHeaderItem();
dependencies.add(CssHeaderItem.forReference(new
CssResourceReference(YuiLib.class,
calendar/assets/skins/sam/calendar.css)));
return dependencies;
}
}
And then in my page:
@Override
public void renderHead(IHeaderResponse response) {
super.renderHead(response);
response.render(CssHeaderItem.forReference(APP_CSS)); //my css
file
response.render(CssHeaderItem.forReference(new
YUICalendarCssResourceReference()));
}
Where yui.css is my custom css
Firstly is the above correct?
The result is that in the source the .css files appear correctly.
However, visually it does not work. Looking at Firebug I have the following
css files loaded:
1) app-ver-.css
2)
wicket/resource/org.apache.wicket.extensions.yui.YuiLib/calendar/assets/skins/sam/calendar-ver-1356690284000.css
3) yui-ver-.css
4)
wicket/resource/org.apache.wicket.extensions.yui.YuiLib/calendar/assets/skins/sam/calendar.css
My understanding is that the 4th css file should not be loaded there.

Re: CSS load order in 6.x
Hi,
I also think that 4) should not be loaded at all.
I guess that YUI itself loads it. YUI supports its own dependency
management.
Check what is rendered by Wicket in the HTML.

Re: Create/Edit domain object data
Nick, I'm not sure if anyone responded, so let me share how we deal with this. Since a JPA entity can reference other (persistent entities), and usually does, we've tried to never, ever, serialize JPA entities. The only time where it's needed is when you have an entity creation workflow which spans more than a single screen. For the cases where an entity is created using a single screen, we simply write a LDM which creates a new instance, setting defaults. Wicket then pushes all form fields to the entity on submit, and as a result we have an entity we can persist. Other possible strategies: - serialize the new entity inside a normal model (Model) - pre-create new entities, and have a flag on them which indicates their workflow state (NEW, ACTIVE etc); that way you can simply load them through whatever EntityDatabaseModel you have in place Met vriendelijke groet, Kind regards, Bas Gooren Op 7-12-2012 19:14, schreef Nick Pratt: Im looking for recommendations on how to work with Form data and a JPA/Hibernate model, specifically around creating and editing domain data. I have a JPA backed domain model, and I want to create a page/panel/form that allows entry of a new Foo, as well as being able to pass an existing LDMFoo to the Page/Panel so that I can edit it. Obviously I'd like to use an IModel for the domain object so that I dont end up serializing the DB in to the session, but at the same time, I cant use an LDM until the new entity is saved and an ID is assigned to the object. For the 'new' case, do you just serialize the domain entity in to the session, IModelFoo model = Model.of( new Foo() ); and let the Foo object be serialized until such time as the Foo.id is set so you can switch out the IModel ref to an LDM? Or is it best to just show the minimal number of fields required (*) to create a new Foo (accessed via PropertyModel(this, attributeName), save it, and then set the LDMFoo reference in the page and then let the other form elements be shown? (This approach duplicates code - the fields in the domain object are duplicated as primitives in the Page (which get serialized in to the session) ) The edit functionality needs to allow all fields to be edited (including the fields mentioned in (*) above) - I dont want to duplicate form markup and code - once for the 'new' case and once for the 'edit' case - the 'edit' case would have a lot more fields that could be entered/edited. Are there other approaches that I'm missing, and what is the best pattern to follow here?
Re: Issue while adding Custom Validator to ListMultipleChoice component
Hi,
This is getting empty when it is loaded with default values.
You mean you have values in your model but they don't show up on a
re-submit?
Please take a look at ListMultipleChoicePage in wicket-examples. If I
add a validator there, everything works as expected:
listChoice.add(new IValidatorCollectionString()
{
@Override
public void validate(IValidatableCollectionString
validatable)
{
CollectionString value = validatable.getValue();
// value is filled with the now selected choices
}
});
Check what's different to your usage.

Able to get the values only when the values or added to the list (i.e, the
component gets modified)
Also, I have observed that, in onSubmit(), the updateModel() iof
ListMultipleChoice() s getting called to set the actual property values, and
so the values are being displayed in in on submit when storing them in
domain objects :-(.
But it is not the case in Validating it :-(
