AbstractPageableView calling IDataProvider.size() when it maybe shouldn't
Hi, I noticed a possible inefficiency in AbstractPageableView's getItemModels() method: /** * This method retrieves the subset of models for items in the current page and allows * RefreshingView to generate items. * * @return iterator over models for items in the current page */ @Override protected IteratorgetItemModels() { long offset = getFirstItemOffset(); long size = getViewSize(); Iterator models = getItemModels(offset, size); models = new CappedIteratorAdapter(models, size); return models; } The getViewSize() method will issue a getRowCount() call which in DataViewBase will call the size() method of the DataProvider: public long getViewSize() { return Math.min(getItemsPerPage(), getRowCount() - getFirstItemOffset()); } As far as I can see, this happens so that the call to getItemModels(offset, size) would not ask for more items, than there is in the underlying provider. However, ListDataProvider defends against getting more items than present in the list: @Override public Iterator iterator(final long first, final long count) { List list = getData(); long toIndex = first + count; if (toIndex > list.size()) { toIndex = list.size(); } return list.subList((int)first, (int)toIndex).listIterator(); } Also databases can handle a LIMIT clause that asks for more rows than present in the dataset. The reason I was looking at this code is a DataView element I'm using on the front page of a public web application that fetches and displays the N most recent entries from a comment table without any paging components added to the DataView and I was seeing a simple "SELECT count(id) FROM comment"-like query taking 9% of all sql time according to JavaMelody for the last few days. I've changed the implementation by overriding the getItemModels() method to call directly getItemsPerPage instead of getViewSize and it got rid of the count selects and everything else seems to be working fine. I'm wondering if there is maybe some other reason why getItemModels() is calling getViewSize instead of getItemsPerPage that I've missed. If not should I create a ticket in jira?

Re: Opening modal window at file upload completion
You can try using Uploadify from code.google.com/p/jqwicket/, which lets you
put event handlers on successful completion. You need to write a separate
servlet to handle upload though, but it's quite straightforward. One small
trick is overriding getEventHandler() so you can pass the javascript
generated to call the behaviour from other javascript components. The
example below uses a uuid to communicate between the upload form and the
servlet.
// ajax behaviour added to parent as bogus onNever event
handler
OnComplete onComplete = new OnComplete(onNever, ip, uuid);
wmc.add(onComplete);
wmc.add(new UploadifyWebMarkupContainer(upload, new
UploadifyOptions().auto(true).multi(false).scriptAccess(always).
script(getRequest().getRelativePathPrefixToContextRoot()
+ upload?uuid= + uuid).onCompleteEvent(onComplete.getEventHandler(;
...
/**
* AJAX behaviour fired when upload is ready
*/
public class OnComplete extends AjaxEventBehavior {
Picture picture;
String uuid;
public OnComplete(String event, Picture picture, String uuid) {
super(event);
this.picture = picture;
this.uuid = uuid;
}
public String getUuid() {
return uuid;
}
@Override
protected void onEvent(AjaxRequestTarget target) {
// servlet stores uploaded image
byte[] bytes = UploadifyServlet.getAndRemoveBytes(uuid);
if (bytes != null) {
PhotoUtil.handleImageUpload(bytes, picture);
}
target.addComponent(getComponent().getParent().getParent());
}
// need to be public
@Override
public CharSequence getEventHandler() {
return super.getEventHandler();
}
}

Even though I'm using the AJAX file upload which shows the progress bar
the submit handler doesn't contain a 'target' parameter required to
bring up a modal.
protected void onSubmit()
{
final FileUpload upload = fileUploadField.getFileUpload();
if (upload != null)

The reason is that I do some processing of the file after uploading and
I want to display to the user the results of that processing. Any ideas?
String not serializable exception coming for interned strings from Model with JRockit/Weblogic
Hi, The following seems to be a bug with JRockit or Weblogic, but maybe someone on this list has seen it before and has a better workaround/solution. We have been developing a Wicket application for a government agency that is going to be used by 15k users. The application will be deployed on a Weblogic cluster running on JRockit and Red Hat. We have been experiencing strange Model object not serializable exceptions coming from Model and traced it back to interned (by the compiler) String objects becoming not serializable after hitting the server with a few hundred parallel users. Once the exception occurs for a given String reference it keeps coming consistently for that reference. The current workaround is a custom Model class that has an overrided setObject method which checks the object if it's instanceof Serializable and if the check fails it sets new String(object) on the Model. This eliminates the exceptions but would like a better solution to the problem. Has anyone seen anything like this?

Re: Could TinyMCE Upload pictures or files
I'm using the following custom tinymce javascript initialization (I
don't use the default which comes with wicket-tinymce, but put this
together manually). I override the image button of tinymce so the
callback can change the whole panel and display a selector one. The
user can use the selector panel to upload new pictures as well, but
that's handled by wicket at that point.
public class FormTinyMceRow extends FormTextAreaRow {
private static final long serialVersionUID = 1L;
public static final ResourceReference REFERENCE_MIN = new
CompressedResourceReference(
InPlaceEditBehavior.class, tiny_mce/tiny_mce.js);
public FormTinyMceRow(String id, String selector) {
super(id, selector);
get(component).setOutputMarkupId(true);
add(JavascriptPackageResource.getHeaderContribution(REFERENCE_MIN));
final AjaxFormSubmitBehaviorImpl b = new
AjaxFormSubmitBehaviorImpl(onNever);
add(b);
add(new Label(script, new ModelString() {
@Override
public String getObject() {
String siteCss =
CmsConfig.getSiteById(((CmsSession)getSession()).getSiteId()).getCss();
return tinyMCE.init({ +

}).setEscapeModelStrings(false));
}
Unfotunately I couldn't get the javascript functions to insert the
image at the right position, so I'm using a string substitution
pattern to do it. My base pages can handle pushing (to display a new
dialog) and popping (to get back to previous content) components into
the main area of my layout:
private class AjaxFormSubmitBehaviorImpl extends AjaxFormSubmitBehavior {
public AjaxFormSubmitBehaviorImpl(String event) {
super(event);
}
@Override
public void onSubmit(AjaxRequestTarget target) {
CmsPage page = (CmsPage) getPage();
ContentSelector selector = new
ContentSelector(page.getMainId(), new Model(), Photo.class) {
@Override
public void close(AjaxRequestTarget target) {
Photo photo = (Photo) getDefaultModelObject();
String replacement = ;
if (photo != null) {
Image image = photo.getThumbnail();
if (image != null) {
replacement =
ImageView.contentImageUrl(image.getId(), 1, null,
photo.getTitle()).toString();
}
}
IModel model =
FormTinyMceRow.this.get(component).getDefaultModel();
model.setObject(model.getObject().toString().replaceAll(%%IMAGE%%,
replacement));
((CmsPage) getPage()).popMainContent(target);
}
};
page.pushMainContent(selector, target);
}
@Override
protected void onError(AjaxRequestTarget target) {
}
// have to make it public
@Override
public CharSequence getEventHandler() {
return super.getEventHandler();
}
@Override

Re: FW: need help urgent......Change label dynamicly
AFAIR a button's label comes from it's Model. So you should do:
new AjaxButton(preview){
public void onSubmit(AjaxRequestTarget target, Form form){
String label = getModelObject(); // or
getDefaultModelObject(); if 1.4
if (click.equals(label) {
getModel().setObject(unclick); // or
getDefaultModel().setObject(unclick) in case you're at 1.4
}
}
}.setModel(click);

Re: Google Analytics and Wicket
Hi Mariana,
Yes, with __trackPageview you can pretty much achieve what you want to do.
In your menu component you probably change the panels by instantiating and
replacing a main panel inside your page, right?
If yes, do something like this:
public void onClick(AjaxRequestTarget target) {
// ... replace, etc
target.appendJavaScript(pageTracker._trackPageview(' + panel trackCode +
'););
}
AjaxRequestTarget.appendJavaScript gets evaluated by the browser at the end
of the AJAX call.
Hope this helps,
Janos

I tried placing the Google Analytics script at the bottom of the homePage

Re: Markup inheritance with child pages setting title in the form 'BasePage.title + - + ChildPage.title'
1. Set an instance variable in the base page called basePageName
You don't need a variable - all you need is a getter:
public IModelString getPageTitleModel() {
return new Model(ApplicationName);
}
2. Use a Label to set the title in the base page
Exactly, like this:
add(new Label(pageTitle, getPageTitleModel());
3. Let child pages append their part to the Label
public IModelString getPageTitleModel() {
return new Model(ApplicationName - Cool Page);
}
Another approach (this way you handle localization and don't have to
override anything in your pages):
public IModelString getPageTitleModel() {
return new StringResourceModel(this.getClass().getSimpleName() +
.PageTitle, this, null);
}
and put
CoolPage.PageTitle=ApplicationName - Cool Page Title
into your application properties file.
Re: URL rewriting
You have to mount your page via MixedParamUrlCodingStrategy:
mount(new MixedParamUrlCodingStrategy(/company, CompanyPage.class, new
String[] {companyName});
and in CompanyPage(PageParameters parameters) constructor do something like
this:
String nameInUrl = parameters.getString();
String company = nameInUrl.substring(0, ...);

Re: Localization issue
why the locale changes does not apply to the components? Are you setting up your components based on your locale in the constructor? Because if you do, then setting a Page object with setResponsePage won't create new component objects for you. Try: setResponsePage(this.getPage().getClass()); - this will forward you to a new instance of the page... - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Localization issue
Actually now I have only one label for testing purposes: add(new Label(locale, getSession().getLocale().getLanguage())); That's actually bad practice. You are adding the component in the constructor. That code runs only once - when you create the component, page, etc. Try: add(new Label(locale, new PropertyModel(this, session.locale.language)); - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Doubt in wicket and multiple views
If you're looking for a way to use different layouts, templates for different virtual servers you have several options: - use the Session.setStyle() to set the style... you can do this in a custom WebRequest and by examining the server name of the request url. Then you can have different .html and .properties file per virtual host, but the same usage. - use a Border to incorporate all style information (adding css reference, the main layout, etc). I prefer this approach - I have an ancestor Page that always adds a border which border is made by a factory method I have on my subclassed webapplication. This way I can create different borders and thus different layouts and styles for different pages - or I could even have different styles based on any request parameters. The second approach can be seen in live at www.szeretgom.hu (sorry it is not available in English yet...) If you navigate to http://szeretgom.hu/portal/content/title/Wiki/ you get a different layout (which is created by a different border). A third kind of border is displayed at this URL: http://szeretgom.hu/portal/blog/pages/cserepj/ These are all handled by the same web application and it would be quite easy to modify my code to return different borders based on the request url's server name...

Re: adding conditional component
How do you guys implement a link that is conditional? Like for example the
link only shows if a given data is provided. Adding the a-tag in the
Markup will coz an error if the condition is not met, because AjaxLink is
not added.
I usually handle such a situation by overriding the isVisible() method of
the component:
add(new Link(link) {
@Override
public boolean isVisible() {
boolean externalCondition = ;
return super.isVisible() externalCondition;
}
});
