[Wicket-user] Spring integration using AspectJ
Hi all, I'm very new to Wicket (with no more than a few hours of fly). I would like to integrate it with the spring AplicationContext/BeanFactory so I've been reading the solutions described in http://www.wicket-wiki.org.uk/wiki/index.php/Spring. I've nothing to object to them but I think it would be possible to get the integration by means of the @Configurable annotation that spring 2 offers too. This annotation injects dependencies upon bean instantiation (ie. with new) based on a prototype scope bean definition. Also from version 2.0.3 onwards this annotation would inject dependencies after deserialization as described in this jira: http://opensource.atlassian.com/projects/spring/browse/SPR-2896. So you can declare your dependencies as transient and expect them to be injected at instantiation-time and at deserialization-time. Weaving can be done at compile-time and at loading-time. If you are already using aspectj with spring, for example for domain object dependency injection, you won't need extra stuff to make it inject Wicket pages' properties. I have written a toy example of this approach and it seems to work fine. What do you think? Maybe I'm missing something. Cheers, Carlos - Take Surveys. Earn Cash.

Re: [Wicket-user] Newbie needs help to generate dynamic content
new textfield(..., new Model(my_textfield_value))
does not know how to react when you change my_text_field_value. Remember:
1. strings are not mutable
2. you pass in a reference, not a pointer
In your case you should use:
new TextField(..., new PropertyModel(this, // <- this is the page
"my_textfield_value"));
If you haven't yet, read [1] which is the primer for understanding models.

Re: [Wicket-user] Newbie needs help to generate dynamic content
Hi Marc-Andre, Hi Eelco,
thank you very much for your very fast answers. Before the code a attempt to
explain you my plan. I try to build a wizard. For usability reasons the
wizard should be able to show and hide form-elements depending on the
users interaction. For example if the user selecet a CheckBox a text with
further information appears or elements that are not needed disappears to
avoid confusion. Or if a CheckBox is selected another CheckBox (not in the
same Group) should also be selected.
In the Code below the value for the TextField "myTextField" should be set,
if a user select or deselect the CheckBox "myCB". Is it possible without
Ajax? For my use there can be a complete PageReload. If yes, how can i tell
my WebPage to refresh it self.
Regards Nico
## My Java Code
public class Test extends WebPage{
//My WebPage Elements
private String text_for_my_textField;
private TextField myTextField;
private CheckBox myCheckBox;
public Test() {
//Instance of myForm
Form myForm = new MyForm("myForm");
//Adding Form to WebPage
add(myForm);
//Instance of a TextField
myTextField = new TextField("myTxT",new
Model(text_for_my_textField));
//Adding TextField to Form
myForm.add(myTextField);
//Instance of a CheckBox
myCheckBox = new CheckBox("myCB",new Model()){
protected boolean wantOnSelectionChangedNotifications()
{
return true;
}
public void onSelectionChanged()
{
text_for_my_textField = "Hello, this Text should be added to
myTextField";
//Or something like
//myTextField.setValue()
}
};
//Adding CheckBox to Form
myForm.add(myCheckBox);
}
//Subclass for my Form
class MyForm extends Form
{
public MyForm(String id)

Re: [Wicket-user] Wicket and Error messages
I think you can have a look at equal input validator which use two text-fields. Using that code a san example you should be able to generate the type of Validator you need that will generate only one message. Hope it helps. Shams Hello Guys, We have the following problem: based on client requirements we have to break the ssn fields into 3 separate text fields. But even if all 3 of them are incorrect we should see just one error message and to have all 3 of them highlighted, since for a client logically it is one field. How can we do it using wicket. What we have seen until now, was that for every field that failed validation there was an error message appearing. In our case while we have to highlight a group of fields, we also have to show only one error message for the group. The other question is how do we make the error messages dynamic.. For example I have 2 address components on the page and both of the components have address 1 and address 2 fields. Still one address shows the address of the person, while the other address shows the address of the person's child. When I have the error message I would have liked to see something like "Member address 1 us missing", not just "address 1 is missing". In other words my messages need to be parameterized based not only on the field name, but also on some property that is stored in Model for the panel that holds other elements.

Please respond to

Regarding filtering of messages, I had asked this earlier which Igor
answered.
http://www.nabble.com/-Wicket-user--Removing-messages-from-FeedBackPanel-tf3058081.html#a8502575
So I created a filter like this:
public class MyFeedbackMessageFilter implements IFeedbackMessageFilter {
private Set previous = new HashSet();
public void reset() {
previous.clear();
}
public boolean accept(FeedbackMessage fm) {
if(!previous.contains(fm.getMessage())) {
previous.add(fm.getMessage());
return true;
}
return false;
}
}
Add this to the FeedbackPanel using setfilter()
You have to "reset" this everytime the form bind-validation cycle happens
else else previous errors will persist, so I override validate() on the
Form to do this:
@Override
protected void validate() {
filter.reset();
super.validate();
}
Hope this helps.

[Wicket-user] Wicket and Error messages
Hello Guys, We have the following problem: based on client requirements we have to break the ssn fields into 3 separate text fields. But even if all 3 of them are incorrect we should see just one error message and to have all 3 of them highlighted, since for a client logically it is one field. How can we do it using wicket. What we have seen until now, was that for every field that failed validation there was an error message appearing. In our case while we have to highlight a group of fields, we also have to show only one error message for the group. The other question is how do we make the error messages dynamic.. For example I have 2 address components on the page and both of the components have address 1 and address 2 fields. Still one address shows the address of the person, while the other address shows the address of the person's child. When I have the error message I would have liked to see something like "Member address 1 us missing", not just "address 1 is missing". In other words my messages need to be parameterized based not only on the field name, but also on some property that is stored in Model for the panel that holds other elements.

Re: [Wicket-user] Working with Tree - onClick() different frame target?
Hi Igor & all,
i implemented it the suggested way by using BookmarkablePageLink +
attribute modifier.
For this i havee sub classed the extension tree and have overwritten the
populateTreeItem as followed:
//
@Override
protected void populateTreeItem(WebMarkupContainer item, int level)
{
if ((item.getModelObject() instanceof
DefaultMutableTreeNode) &&
((DefaultMutableTreeNode)
item.getModelObject()).getUserObject() instanceof IConfigurationPage){
populateMyTreeItem(item, level);
return;
} else
{
super.populateTreeItem(item, level);
return;
}
}
protected void populateMyTreeItem(WebMarkupContainer item, int level)
{
final DefaultMutableTreeNode mutableTreeNode =
(DefaultMutableTreeNode) item.getModelObject();
item.add(newIndentation(item, "indent", (TreeNode)
item.getModelObject(), level));
item.add(newJunctionLink(item, "link", "image",
mutableTreeNode));
MarkupContainer nodeLink = newCustomNodeLink(item,
"nodeLink", (IConfigurationPage) mutableTreeNode.getUserObject());
item.add(nodeLink);
nodeLink.add(newNodeIcon(nodeLink, "icon", mutableTreeNode));
nodeLink.add(new Label("label", new AbstractReadOnlyModel() {
private static final long serialVersionUID = 1L;
public Object getObject(Component c)
{
return renderNode(mutableTreeNode);
}
}));
item.add(new AttributeModifier("class", true, new
Model("row")));
}
protected MarkupContainer newCustomNodeLink(MarkupContainer parent,
String id,
IConfigurationPage page)
{
PageParameters param = new PageParameters();
param.put("configPage", page.getID());
BookmarkablePageLink pLink = new BookmarkablePageLink(id,
ConfigMainPage.class, param);
pLink.add(new AttributeModifier("target", true, new
Model("main")));
return pLink;
}
//
So in this case only the IConfigurationPage nodes will get a different
nodeLink -> newCustomNodeLink.
This works so far pretty good - the only problem is now when i click on
a custom link and afterwards on a plus or minus i receive the following
exception:
//-
WicketMessage: component border:configOutliner:i:1:nodeLink not found on

Re: [Wicket-user] Hibernate/Spring and Wicket architecture "request for validation" (was Wicket's questions)
I know I wasn't asked ;) but we had to revisit this question recently
in converting a Tapestry app over to Wicket. We started off trying to
use Hibernate objects directly for the usual reasons (avoid code
duplication, more elegant, etc.) but ran into a few problems.
A small but important problem was that we had to alter domain objects
in less than ideal ways to account for the fact than any setter could
be called at any time. This meant making some private setters public
and adding redundant validation and logic that would normally go into
a dedicated, multi-parameter "update..." method meant for public use.
The biggest problems were related to transaction rollbacks after save
()-ing or reattaching Hibernate objects. Once you save a new object,
Hibernate marks it as persistent but, if it didn't actually get
committed to the database because your transaction rolled back, it's
in an invalid state and Hibernate won't let you reattach it.
Similarly, if you reattach an edited object and then the transaction
rolls back, that object will be invalid. To solve this, we ended up
reloading or recreating domain objects after transaction rollbacks
and copying user-supplied values from the old object to the new one.
Needless to say, that code looks a lot like what you have to do with
form beans, except uglier.
We avoided lazy load issues and transaction scope problems by using a
read-only session per view and transactional service methods (a
pretty standard architecture). Those parts worked fine.
In the end we decided to go with form beans only because it ends up
being a little simpler, keeps UI and domain needs separated and was
actually slightly less code if you don't count the auto-created
getters and setters on the form beans.
I still think using Hibernate objects directly can be a nice way to
go, and if you don't mind the inconsistency you might find that some
forms can do that while others use beans.
These model classes (based on an old post of Igor's) helped me
immensely with Wicket/Hibernate integration. We still use them to
back our DataTables and most of our view pages (which use Hibernate
objects directly). The first is a superclass for any Hibernate
entity. The second is an example subclass for use with a domain
supertype.
public class EntityModel extends LoadableDetachableModel {
private final Class clazz;
private final Serializable id;
public EntityModel(Class clazz, Serializable id) {
this.clazz = clazz;
this.id = id;
}
public EntityModel(Class clazz, Serializable id, Object object) {
super( object );
this.clazz = clazz;
this.id = id;
}
@Override
protected Object load() {
return HibernateSessionLocator.getSession().get( this.clazz,
this.id );
}
}
public class DomainSupertypeModel extends EntityModel {
public DomainSupertypeModel(DomainSupertype object) {
super( object.getClass(), object.getId(), object );
}
// If the object is a proxy, its runtime type might not be the actual
// persistent class, so sometimes you need to specify it.
public DomainSupertypeModel(DomainSupertype object, Class clazz) {
super( clazz, object.getId(), object );
}
}
hth,
