Re: VOTE: Generics of IDataProvider

[ ] Leave as is.
Leaving it as is just doesn't make sense as it doesn't support the use case
on hand.
Using IDataProvider is OK too. For those whose I == T, we can always
have a convenient base class:
abstract class ModelProvider implements IDataProvider {
IModel model(T object) {
return object;
}
}
Iterator> will make the interface simpler. For those who
need to wrap domain objects as models, we can provide a wrapper
iterator:
abstract class ModelWrapperIterator implements Iterator {
ModelWrapperIterator(Iterator source) {
...
}
abstract IModel map(T sourceElement);
}

Re: users, please give us your opinion: what is your take on generics with Wicket

"required" for Checkbox
Hi, I observed that if "required" is set to true for a Checkbox, Wicket will ensure that the Checkbox is checked. If it is cleared by the user, it will be treated as an error. See https://issues.apache.org/jira/browse/WICKET-1221 and https://issues.apache.org/jira/browse/WICKET-1260 for some background. For me, "required" means that a value must be provided. For a check box, if it is checked, it has a value of true. if it is unchecked, it has a value of false. So it always satisfy "required". Treating "required" as "having a value of true" doesn't sound correct to me. If we consider the error message that should be used, for the case of forcing the user to check the box (eg, [x] I have read the agreement), it should say "you must check xxx", which is quite different from the error message for "required": "you must provide xxx". For the use case of forcing a checked check box, I think an CheckedValidator should be used, which can provide a much better default error message. Not that it's an important, but just to see what others think. - -- Kent Tong Wicket tutorials freely available at http://www.agileskills2.org/EWDW Axis2 tutorials freely available at http://www.agileskills2.org/DWSAA -- View this message in context: http://www.nabble.com/%22required%22-for-Checkbox-tp14662131p14662131.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I don't know why you feel this hacky. It looks clean and easy to me:
public class TestPage extends WebPage {
@SpringBean(name = "config")
private Config config;
public TestPage() {
add(PanelFactory.getPanel(config, "testPanelOne"));
}
}
public class PanelFactory {
public static Panel getPanel(Config config, String id) {
Class c =
Class.forName(config.getPanelClass()).asSubclass(Panel.class);
Constructor constructor =
c.getConstructor(String.class);
return constructor.newInstance(id);
}
}

You can certain make the PanelFactory a spring bean:
public class TestPage extends WebPage {
@SpringBean(name = "panelFactory")
private PanelFactory panelFactory;
public TestPage() {
add(panelFactory.getPanel("testPanelOne"));
}
}
myapp.TestPanel
The Wicket Classes class is not meant for performance. Normal classloaders
probable
provide better caching support. It was introduced to fix concurrency
problems.

The mime type Wicket returns to the browser is text/. In
your case it's text/xhtml which is not correct. Instead, one should use
application/xhtml+xml or text/html. The problem is that IE doesn't support
XHTML at all, so you have to use text/html and let all browsers treat the
response as html, not xhtml.
Wicket could be enhanced to differentiate between the template file
extension and the mime type.
For your case, try below as a workaround (or simply name your files
as *.html):
public class MyPage extends WebPage {
public String getMarkupType() {
return "xhtml";
}
protected void configureResponse() {
super.configureResponse();
getResponse().setContentType("text/html");
}
}

Re: Using Include and placing pages under WEB-INF
Thanks, yes, my solution was close to this, but I opted instead to subclass the Include class. I think the solution that you propose below may cause wicket to create an absolute URL to the HTML files under the WEB-INF dir which will be inaccessible by the browser. /quote> No. The URL is never sent to the browser.

Please file a bug report at http://issues.apache.org/jira/browse/WICKET. The
bug is,
RelativePathPrefixHandler creates auto-components but are not marking them
as
transparent resolver:
public boolean resolve(MarkupContainer container, MarkupStream
markupStream, ComponentTag tag)
{
if
(WICKET_RELATIVE_PATH_PREFIX_CONTAINER_ID.equals(tag.getId()))
{
final Component wc;
String id = WICKET_RELATIVE_PATH_PREFIX_CONTAINER_ID +

else
{
//problem:

If your code was like:

public QueryDetachableModel(Object instance) {
super(instance);
}
protected Object load() {

}
then your obj should no longer be in the session.

This is done automatically in deployment mode. In development mode, you can
enable it like:
public class MyApp extends WebApplication {
protected void init() {
getExceptionSettings().setUnexpectedExceptionDisplay(
IExceptionSettings.SHOW_INTERNAL_ERROR_PAGE);
}
}
This will display wicket's internal error page. If you need to provide your
own
page, try:
getApplicationSettings().setInternalErrorPage(MyErrorPage.class);

You may try my code below which seems to work, even though it's not using

ITreeState treeState = tree.getTreeState();
treeState.collapseAll();
treeState.addTreeStateListener(new ITreeStateListener() {

myTreeNode.add(new
MyTreeNode(childName));
}
}
}
public void nodeCollapsed(TreeNode node) {

Label associated with an open/close tag
Hi, I think this is one of the most common gotcha's in Wicket: a Label associated with an open/close tag like will silently output nothing. As I really can't think of a use case when this behavior is the desired behavior (wanting the Label to output nothing?), I'd suggest that either it changes it to , or simply throw an exception or log a warning. -- View this message in context: http://www.nabble.com/Label-associated-with-an-open-close-tag-tf4506567.html#a12852634 Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Try using a modifier like this:
private static class BoundHighlighter extends AttributeModifier {
private Component owner;
public BoundHighlighter() {
super("class", true, null);
}
protected String newValue(String currentValue, String
replacementValue) {
int idx = getItemIndex();
return idx == 0 ? "first" : (idx == getItemCount() - 1
? "last"
: null);
}
public void bind(Component component) {
super.bind(component);
this.owner = component;
}
private int getItemIndex() {
return getItem().getIndex();
}
private Item getItem() {
Component parent = owner.getParent();
while (!(parent instanceof Item)) {
parent = parent.getParent();
}
return (Item) parent;
}
private int getItemCount() {
return getItem().getParent().size();
}
}
The code below uses it for a Label contained in a repeater Item:
public Home() {
RefreshingView view = new RefreshingView("view") {
protected Iterator getItemModels() {
List models = new ArrayList();
int n = 2+new Random().nextInt(10);
for (int i = 0; i < n; i++) {
models.add(new Model(i));
}
return models.iterator();
}
protected void populateItem(Item item) {
item.add(new Label("label", item.getModel())
.add(new BoundHighlighter()));
}
};
add(view);
}

The code below seems to work for a RepeatingView. Of course it is a hack as
it depends on the
order in which the children are visited. However, it doesn't depend on
notification of objects
being attached to the parent. The bind() method is called when the behavior
is added to the
component.
public class Home extends WebPage {
private static class BoundHighlighter extends AttributeModifier {
private Component owner;
public BoundHighlighter() {
super("class", true, null);
}
protected String newValue(String currentValue, String
replacementValue) {
int idx = getItemIndex();
return idx == 0 ? "first" : (idx == getItemCount() - 1
? "last"
: null);
}
public void bind(Component component) {
super.bind(component);
this.owner = component;
}
private int getItemIndex() {
final int[] idx = { -1 };
Object result = owner.getParent().visitChildren(new
IVisitor() {
public Object component(Component component) {
idx[0]++;
return component == owner ? idx[0]
:
CONTINUE_TRAVERSAL_BUT_DONT_GO_DEEPER;
}
});
return (Integer) result;
}
private int getItemCount() {
return owner.getParent().size();
}
}
public Home() {
RepeatingView view = new RepeatingView("view");
view.add(new Label("x", "a").add(new BoundHighlighter()));
view.add(new Label("y", "b").add(new BoundHighlighter()));
view.add(new Label("z", "c").add(new BoundHighlighter()));
view.add(new Label("t", "d").add(new BoundHighlighter()));
add(view);
}
}

Then add the behaviors in onBeforeRender():

public MyRepeatingView(String id) {
super(id);
}

super.onBeforeRender();
int idx = 0;

});

idx++;

As I said, you can enable wantOnSelectionChangedNotifications() to refresh
the whole page. Here
is some sample code:
public class WizardTest extends WebPage {
private String selected = "A";
public WizardTest() {
WizardModel wizardModel = new WizardModel();
wizardModel.addListener(new IWizardModelListener() {
public void onFinish() {
setResponsePage(Completed.class);
}
public void onCancel() {
}
public void onActiveStepChanged(IWizardStep newStep) {
}
});
wizardModel.add(new MyStep("a"));
wizardModel.add(new MyStep2(new PropertyModel(this,
"selected")));
wizardModel.add(new MyStep("c"), new ICondition() {
public boolean evaluate() {
return "A".equals(selected);
}
});
Wizard w = new Wizard("w", wizardModel);
add(w);
}
}
public class MyStep2 extends WizardStep {
public MyStep2(IModel model) {
List options = new ArrayList();
options.add("A");
options.add("B");
add(new DropDownChoice("s", model, options) {
protected boolean wantOnSelectionChangedNotifications()
{
return true;
}
});
}
}

detachChildren() is overriden by MarkupContainer which does detach its
children
(see below). So there must be something wrong with your unit test.
void detachChildren()
{
// Loop through child components
final Iterator iter = iterator();
while (iter.hasNext())
{
// Get next child
final Component child = (Component)iter.next();
// Call end request on the child
child.detach();
}
super.detachChildren();
}

I suppose you're using wantOnSelectionChangedNotifications() to trigger
the refresh? In that case it won't refresh any input entered by the user.
Validation plays no role here because such a form refresh does NOT invoke
the validation logic.
In order to refresh the data and erase what the user has entered, call
clearInput() on the form:
ListChoice recommendation = new ListChoice("recommendation", ...) {
protected boolean wantOnSelectionChangedNotifications() {
return true;
}
protected void onSelectionChanged(Object newSelection) {
recommendationForm.clearInput();
}
};

I used your code and the test passed. Here is my test page:
test
public class Test extends WebPage {
public Test() {
ListView listView = new ListView("listView", Arrays
.asList(new String[] { "a", "b" })) {
protected void populateItem(final ListItem item) {
item.add(new Label("labelWithDetachableModel",
new
LoadableDetachableModel() {
protected Object load() {
return item.getModelObject();
}
}));
}
};
add(listView);
}
}
However, I really think your test case is broken. After startPage() returns,
the page has been detached. Why it passes on my computer is because
of your call to debugComponentTrees(). Therefore, you should really be
testing if the model is now detached. That's it. By checking the output
you can be sure that the model was once attached.

No, your mail client has stripped the code. Let me show you the code again:
test
public class Test extends WebPage {
public Test() {
ListView listView = new ListView("listView", Arrays
.asList(new String[] { "a", "b" })) {
protected void populateItem(final ListItem item) {
item.add(new Label("labelWithDetachableModel",
new
LoadableDetachableModel() {
protected Object load() {
return item.getModelObject();
}
}));
}
};
add(listView);
}
}
Run the test case and it will pass (although for the wrong reason).

Even though you're not using wantOnSelectionChangedNotifications(),
what I said applies: you need to call clearInput() like:
ListChoice lc = new ListChoice("lc", ...);
lc.add(new OnChangeAjaxBehavior() {
protected void onUpdate(AjaxRequestTarget target) {
recommendationForm.clearInput(); //THIS LINE IS WHAT

Generally we don't want to lose that input (because all you want to do may be to show or hide a certain component depending on the selection), therefore it is saved and redisplayed to the user.

I'd suggest that it extend Panel, not FormComponentPanel as there is no
composite data structure here. The best place to validate the input is
in a custom validator. Here is some sample code (there is also step-by-
step instruction on validation in my tutorials; see my signature):
public class CaptchaPanel extends Panel {
private static class CaptchaValidator extends AbstractValidator {
protected void onValidate(IValidatable validatable) {
String value = (String) validatable.getValue();
if (value matches the image) {
return;
}
error(validatable);
}
}
public CaptchaPanel(String id) {
super(id);
RequiredTextField t = new RequiredTextField("captchaInput", new
Model());
t.add(new CaptchaValidator());
add(t);
add(new Image("captchaImage", ...));
}
}

nonzero positive or negative: do as Gwyn suggested. If you insist on using a
pre-built
validator, try PatternValidator("[+|-]?(\\d)*[1-9](\\d)*") but then the
model has to
be a String, not a number.
