Re: Wicket 1.5 - ModalWindow with page - abstract functions do not update model correct
Hello,
Thanks for the response !
I'm not sure if the following code is what you want. I just update the
pageValue variable on the HomePage in the abstract function 'linkClicked'.
Following code is inside the HomePage constructor:
pageValue = initial modal value;
final ModalWindow window = new ModalWindow(window);
window.setPageCreator(new ModalWindow.PageCreator() {
public Page createPage() {
return new ModalWindowPage(getPage().getPageReference()) {
@Override
public void linkClicked(String value) {
System.out.println(setting pageValue to [ + value
+ ]);
pageValue = value;
}
};
}
});
window.setWindowClosedCallback(new
ModalWindow.WindowClosedCallback() {
public void onClose(AjaxRequestTarget target) {
System.out.println(getting pageValue [ + pageValue + ]);
}
});
I get the following console output:
setting pageValue to [ModalWindowPage value]
getting pageValue [page value]
Thanks for the hint tot the inter-component events.
Should I then pass the Panel or Page as IEventSink to the constructor of the
ModalWindowPage so I can use it in the send-function?
I'm afraid I will forget to catch the event with the onEvent function. With
the abstract function I was sure that the event was catched...
How come this did work in wicket 1.4 and now functionality is lost?
Thanks for any help ! Marieke Vandamme

Re: Wicket 1.5 - ModalWindow with page - abstract functions do not update model correct
Hi,
I just tried it with the inter-component events, and it's the same problem
as with the abstract functions..
Please try my code:
HomePage:
public class HomePage extends WebPage {
@Override
public void onEvent(IEvent? event) {
super.onEvent(event);
if (event.getPayload() instanceof String){
String value = (String)event.getPayload();
System.out.println(setting pagevalue to [ + value + ]);
((MyBean)getDefaultModelObject()).setValue1(value);
}
}
public HomePage (){
MyBean myBean = new MyBean();
myBean.setValue1(initial value);
setDefaultModel(new ModelMyBean(myBean));
final ModalWindow window = new ModalWindow(window);
window.setPageCreator(new ModalWindow.PageCreator() {
public Page createPage() {
return new ModalWindowPage(getPage());
}
});
window.setWindowClosedCallback(new
ModalWindow.WindowClosedCallback() {
public void onClose(AjaxRequestTarget target) {
System.out.println(getting pageValue [ +
((MyBean)getDefaultModelObject()).getValue1() + ]);
}
});
add(window);
add(new AjaxLink(lnk) {
@Override
public void onClick(AjaxRequestTarget target) {
window.show(target);
}
});
}
public class MyBean implements Serializable {
private String value1;
/**
* @return the value1
*/
public String getValue1() {
return value1;
}
/**
* @param value1 the value1 to set
*/
public void setValue1(String value1) {
this.value1 = value1;
}
}
}
ModalWindowPage:
public class ModalWindowPage extends WebPage {
public ModalWindowPage(final IEventSink eventSink){
add(new AjaxLink(btn) {
@Override
public void onClick(AjaxRequestTarget target) {
send(eventSink, Broadcast.EXACT, ModalWindowPage value);
ModalWindow.closeCurrent(target);
}
});
}
}
Console output:
setting pagevalue 2 to [ModalWindowPage value]
getting pageValue [initial value]
Thanks a lot ! Marieke Vandamme

Users, sessions, data...
Hi, My last attempts to fix my session and advices here made me thinking if my approach is good. So I'm curious - how do you handle users and their data? In my case I have session, when user logs in entire entity gets loaded into session. Later I get user data from that session and when he changes anything it gets persisted to db. There is no direct interaction between user and only that user can access his data. What is your approach? :) -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Users-sessions-data-tp3598626p3598626.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Re: AutoCompleteTextField which uses an Object, not a String
Yesterday while playing with AutoCompleTextField, I created a quickstart to show how it is 'broken'. I hadn't thought of using a converter. After using a converter the component behaves as I'd expect. So a simpler solution could be: 1) improve the AutoCompleteTextField's java doc to explain using the converter 2) update the wicketExample page to include an example using a converter, 3) add some logic, or an ease of use hook so that AutoComplete can detect when its being used against objects that aren't strings and is breaking. I'll open a Jira, attach the quickstart and attach a patch that takes care of those 3 pieces. Yesterday I glanced at the ObjectAutoComplete and it looks very powerful, but maybe even more complex. My initial desire was that an AutoCompleteTextField mirror how a DropDownChoice behaves by default. I'll try to demonstrate that in my patch. -Clint On Tue, Jun 14, 2011 at 10:51 PM, Igor Vaynberg igor.vaynb...@gmail.comwrote: we dont need to deprecate the existing one. it does something that object-autocomplete does not - lets you enter free-form-text with some assistance. -igor On Tue, Jun 14, 2011 at 6:55 PM, Jeremy Thomerson jer...@wickettraining.com wrote: I'd be up for at least moving the ObjectAutoComplete into core and adding @Deprecated to the existing one before 1.5.0 if there is consensus on it. -- Jeremy Thomerson http://wickettraining.com *Need a CMS for Wicket?

Re: Users, sessions, data...
One subtle gotcha to consider is that Wicket does not synchronize access to your Session object when processing multiple requests by the same user. Marking your Session's getters and setters as synchronized is sufficient for simple data members, but typical use of entities cannot be considered thread-safe. (With Hibernate this is clear because attached entities are associated with a single Hibernate Session, which is definitely not thread-safe. I'm not sure of the JPA equivalent terminology.) For this reason, I maintain only the user ID in the Wicket Session, and subclass WebRequestCycle to maintain request-scoped entities. (Your WebRequestCycle is only used by the single thread servicing the request.) Thanks to Igor and his Apache Wicket Cookbook for drawing my attention to this issue. :) Dan On Wed, Jun 15, 2011 at 6:34 AM, Zeldor pgronkiew...@gmail.com wrote: Well, I'm hosting it on GAE and with new pricing model I have to worry about instances, not memcache or things like that.

Re: Deploiment problem of wicket application with Jboss 5.1
The workaround is not so far.
I try to put the target directory as a key of the vfs.xml file and it
works. It duplicates only once files so no more problem of space.
BUT it is not so good for me as each developer has directory different,
and when we work with remote server, the directory is where wagon is
copying file. JMX lets file where they are.
I go back with my question about wicket, because of, with any other ear
without wicket, there is no problem.
What is doing wicket to give jboss a such problem ?

TextField and Java Number
I am creating an input field that should accept numbers only, so I defined my TextField component as follows, TextFieldNumber(String markupId, IModelNumber model) I am forcing the model update by adding AjaxFormComponentUpdatingBehavior(onblur)... The model doesn't appear to be getting updated (works okay if defined as TextFieldString). I am wondering if the alternate constructor format is required to make it work with types not derived from a String, as in, TextFieldNumber(String markupId, IModelNumber model, Number.class) // explicitly specify the type I thought moving to support generics in wicket eliminated the need for this kind of syntax. Is specifying the type (e.g., class) the solution, or do I need to add a specific type converter for type Number??? Thanks, J.D.

Re: Deploiment problem of wicket application with Jboss 5.1
Yes, before deploying and using the wicket application, I have had 4Go space left on my disk. After, 0 octet is left as the [Jboss_home]/default/tmp/vfs-nested.tmp directory growing as non sense with with jar and war contained into the ear were duplicated as space left. It is as wicket find that the ear change and force to redeploy and then jboss find that the ear change and redeploy and so on until that no more space left. It appends on my windows machine, but also on our linux machine were we integrate the application.

wicket-rest and Wicket 1.5-RC4.2: MarkupNotFoundException: Can not determine Markup
Hi, I've tried to port http://wicket-rest.googlecode.com/svn to Wicket 1.5-RC4.2. That took some minor changes like the package that PageParameters is in, the way the HttpServletRequest is fetched and the onRender methods. All compiles well. However, when I make a request in a browser for a URL like http://localhost:8080/wicket-rest-example/person-api/xml;, I get errors like this one: org.apache.wicket.markup.MarkupNotFoundException: Can not determine Markup. Component is not yet connected to a parent. [Page class = org.innobuilt.wicket.rest.example.pages.PersonXmlRestService, id = 2, render count = 1] When using Wicket 1.4.x, that all works fine. Does anyone have an idea what is going on?

How do I create a detachable model for a ListView?
I am trying to create a ListView using a detachable model, but I just
can't seem to figure out how to construct my DetachableModel. Basically, I
would like to create a detachable model and then pass it to my constructor
for a CheeseList. This is built upon the code for the examples for
Wicket in Action [1] by Dashorst in Chapter 4.3. My DAO can return the
cheese based upon id or it can also return the list of cheeses. What
code do I need to put in CheeseDetach for my detachable model?
CheeseDAO myDAO = new CheeseDAOImpl();
// Can I make CheeseDetach construct it using the DAO as follows?
CheeseDetach myDetach = new CheeseDetach(myDAO);
// ListView can take list or Model as constructor.
// How does the model work for a ListView?
CheeseList myCheeseList = new CheeseList(cheeses, myDetach,
getCart());
// Add ListView to page
add(myCheeseList);

Re: How do I create a detachable model for a ListView?
Look carefully at the ListView's constructor arguments. It wants an IModelListCheese, not an IModelCheese which is what your current CheeseDetach provides. Depending on your goals, you can either (1) change CheeseDetach.load() to call getCheeses(), or (2) change the constructor to accept a list of cheeses and retain a list of cheese IDs, and query for those cheeses individually in CheeseDetach.load().

Re: How do I create a detachable model for a ListView?
Dan, thank you for pointing that out. That makes more sense. So, it looks
like now that my List of Cheeses will not get cached between pages saving
space? And this is because the model doesn't do anything for detach but
only does load, so every time, it will get it from the DAO?
Here is the code for my index page. Supporting code files are attached.
public class Index extends CheesrPage {
public Index() {
CheeseDAO dao = new CheeseDAOImpl();
CheeseDetach myDetach = new CheeseDetach(dao);
CheeseList myCheeseList = new CheeseList(cheeses, myDetach,
getCart());
add(myCheeseList);
