Re: How to refresh component many times in one ajax request
What you're doing right now is to send a request to the server, iterate a
hundred times, replace a component a hundred times, even before the response
from the server reaches the client again.
That what you want to achieve would involve 100 ajax requests and responses,
it IS feasable, but better try a javascript-solution, because 100 roundtrips
is just too much if it's just for changing the label to a fixed value.
But if it's more than that, AjaxSelfUpdatingBehavior might be your friend

Re: dynamic url
I really don't get your point. If there is content which only a selected group of visitors should see, a role based authentication/authorization would be appropriate.

Re: Format date column in DefaultDataTable
Likewise, I'm not sure if its the "best" way but i generally create a quick FormattedPropertyColumn class that extends PropertyColumn and creates the formatted label model with java.text.MessageFormat for number/currency/date formatting purposes Cheers, Jason On Dec 17, 2007 11:03 PM, Stefan Lindner <[EMAIL PROTECTED]> wrote: > I use two solutions for this (depends on the situatioin) > 1.

RE: Format date column in DefaultDataTable
I use two solutions for this (depends on the situatioin) 1. Define your own Date class (e.g. class MyDate extends Date), write a Converter for MyDate, add a method getMyDate to your data class and write columns.add( new PropertyColumn( new Model( "Call Received" ), "callReceived", "getMyDate" ) ); 2. Override the populateItem method of the PropertyColumn class e.g. place a simple Label with the String representatin of your Date into the table cell Maybe there is a better way to do this and I can learn from the communito too.

How to refresh component many times in one ajax request
Hi!
I try to do something like this
final Label counterLabel = new Label("counter", new
PropertyModel(this,
"counter"));
counterLabel.setOutputMarkupId(true);
add(counterLabel);
Form form = new Form("form");
add(form);
form.add(new AjaxButton("confirmButton") {
@Override
protected void onSubmit(AjaxRequestTarget target, Form
form) {
for (int i=0; i <100; i++ ) {
synchronized (this) {
try {
wait(1000);
} catch (InterruptedException
e) {
e.printStackTrace();
}
counter += i;
target.addComponent(counterLabel);
}
}
}
});
The component doesn't refresh. Only for the last time. How to make it work?
Thanks,
Artur

Problem with AjaxTabbedPanel, Form and PageMap
I have an AjaxTabbedPanel with several tabs, each containing a form. There is
nothing fancy about the forms, there are just text fields and checkboxes.
Sometimes when I submit the form, I get the error:
INFO [AccessStackPageMap] Unable to get version N of page [Page class =
my.com.MyPage, id = M, version = X, ajax = 0]
I'm setting the response page to the page that contains the tabbed panel, as
follows:
Button ok = new Button("myid")
{
@Override
public void onSubmit()
{
// sql update goes here...
setResponsePage(parentPage);
}
};
form.addButton(ok);
add(form);
Any insight is appreciated.
Thanks,
Julian

Re: dynamic url
I'm new to wicket too, but my guess is that if you tried the URL in a new browser entirely (or if you quit and re-opened your browser), the URL wouldn't work any more. New tabs still have all the cookies that the old tabs have, which works out nicely in many cases. They're extensions of the current session, not new sessions. Hope I understood your problem correctly, Alex On Dec 17, 2007, at 4:10 AM, tbt wrote: Hi I'm a newbie to wicket and I'm using a WebSession to log users into my application.

Re: WicketNotSerializableException
it's the ApplicationContextFacade that can't be serialized. you'll need to mark this field as transient most likely. Now, if this is, as I suspect, a spring class for getting your dependencies, you'll have to refetch/recreate this context after deserialization. But if you're using spring you should really look at wicket-spring and use @SpringBean to get your deps handed to you.

Re: Wicket + OSGI + Session
Hi,
Thank you for your suggestion. I have no time to look at this earlier,
but Wicket 1.3.0-rc2 is out now and after upgrade the error message I
have has changed to:
java.lang.IllegalStateException: spring application context locator
returned null
at
org.apache.wicket.spring.SpringBeanLocator.getSpringContext(SpringBeanLocator.java:180)
at
org.apache.wicket.spring.SpringBeanLocator.locateProxyTarget(SpringBeanLocator.java:162)
at
org.apache.wicket.proxy.LazyInitProxyFactory$JdkHandler.invoke(LazyInitProxyFactory.java:412)
at org.apache.wicket.proxy.$Proxy82.getAction(Unknown Source)
So it seems there is a problem with deserialization of spring
application context locator. I have used my own locator implementation
(OsgiSpringContextLocator). There is one locator created for each
application context and there was a map of locators and app contexts.
Locator reference was the key in this map (very, very bad thing :)):
private static Map
applicationContexts = new HashMap();
I have changed this now to:
public class OsgiSpringContextLocator implements ISpringContextLocator {
private static Map applicationContexts
= new HashMap();
private static int appContextCounter = 0;
private Integer appContextId;
OsgiSpringContextLocator(ApplicationContext applicationContext) {
appContextCounter++;
appContextId = new Integer(appContextCounter);
applicationContexts.put(appContextId, applicationContext);
}
public ApplicationContext getSpringContext() {
ApplicationContext result = applicationContexts.get(appContextId);
return result;
}
}
So each appCtxt has its own unique index (appContextId) which is
stored in locator, so locator is able to find a proper appCtxt by this
id (even after deserialization)
This is a quick fix that works, maybe in the future I will implement
this in a more elegant way ;).

Dear all, I got this message because there is a field that Wicket wants to serialize but it can not be serialized. Now how do I remove this error since I can not make tomcat's ApplicationContextFacade to be Serializable. 2007-12-17 17:49:12,498 - [ERROR] - Objects- Error serializing object class com.mycompany.dupe.pages.PricePage [object=[Page class = com.mycompany.d upe.pages.PricePage, id = 17, version = 0]] org.apache.wicket.util.io.SerializableChecker$WicketNotSerializableException: Unable to serialize class: org.apache.catalina.core.ApplicationContextFacade Field hierarchy is: 17 [class=com.mycompany.dupe.pages.PricePage, path=17] private java.lang.Object org.apache.wicket.MarkupContainer.children [class=[Ljava.lang.Object;] private java.util.List com.mycompany.dupe.pages.PricePage$PriceForm.prices[8] [class=com.mycompany.dupe.pages.PricePage$GeneratorForm, path=17:generatorForm] javax.servlet.ServletContext com.mycompany.dupe.pages.PricePage$GeneratorForm.context [class=org.apache.catalina.core.ApplicationContextFacade] <- field that is not serializable Thanks in advance -- I'm a coder not a drag-n-dropper Blog: http://joshuajava.wordpress.com/ - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: java.lang.OutOfMemoryError: Java heap space
It's not possible to help you without knowing seeing more code. What are the items you are creating? It's probably the models itself that cause the outofmemory error, you are likely to be loading someting huge. -Matej On Dec 17, 2007 6:12 AM, kenixwong <[EMAIL PROTECTED]> wrote: > > hi, anyone can help ? > > i was using the Eclipse 3.2.2, jdk1.6.0, jetty 6.0.2, wicket 1.2.4.

Wicket 1.3.0-rc2 and WebSphere 5.1 Http status 302
I am writing an web application that uses Wicket 1.3.0-rc2 and it should run on WebSphere 5.1. In web.xml I am using the WicketFilter mapped with the URL pattern /admin/* I install the application in WebSphere 5.1 and when I access the home page it works. The URL that I am using is like: http://host/application/admin. When I click on a link the browser makes the request to : http://host/application/admin/? and server responds with the status 302 with the location: http://host/application/?, it removes the admin. The application works fine in Tomcat, JBoss (4.2.2 and 3.2.6) and in WebSphere 6.1 As a solution I've configured the WicketServlet in web.xml and now it works also on WebSphere 5.1 Did anybody encountered the same problem with WicketFilter and WebSphere 5.1? Is there any advantage with using the WicketFilter instead of using the WicketServlet? -- View this message in context: http://www.nabble.com/Wicket-1.3.0-rc2-and-WebSphere-5.1-Http-status-302-tp14370196p14370196.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]
Re: "Streaming" a huge ZIP file
you can't update a page and download in 1 request. You have to do this in 2.

dynamic url
Hi I'm a newbie to wicket and I'm using a WebSession to log users into my application. When navigating through the pages wicket generates a dynamic url such as http://192.222.7.66:8080/oem?wicket:interface=wicket-1:0:: But if you copy this url and paste it in a seperate tab the inner page is displayed. As a result users can view data without giving the username and password. How can I stop this.

Re: "Streaming" a huge ZIP file
Hi, This looks completely straight-forward, we'll switch to it as soon as move to rc3. On Dec 16, 2007 8:33 PM, Johan Compagner <[EMAIL PROTECTED]> wrote: > RequestCycle.get().setRequestTarget(new ResourceStreamRequestTarget(writer," > test.zip")); Maybe this is dumb, but if I encounter an exception in the write method (during content generation), can I "unsnatch" the stream and hand it back to wicket for displaying regular pages? I realise the headers like content type and even some content might have been streamed out already, but who knows. Slightly related, what would be the best way for a single onclick() event to result in both a wicket page refresh and a download?
