Re: Component initModel() order (design issue?)
Can't be done, because the component does not yet know its parent during object
initialization. initModel/getDefaultModel needs to be called later, when the
component knows its place in the hierarchy. by giving the child component a
model that obtains the model from its parent (MyTextfield) the call to
getDefaultModel is delayed and it works.

why not
class mytextefield extends panel {
public mytextfield {
add(new textfield() { initmodel() { return
mytextfield.this.getdefaultmodel(); }});

since this is essentially what you want to do - have textfield use the
same model as the panel.

You're right, getDefaultModel ensures initialization. I should have suggested
that instead of getModel (which is not available in the component class
anymore
in 1.4.x).
However, I did not want to override the initModel() method (and copy most of
its
code) just for that. So now I solved it by creating a new wrap model, which I
pass to the child component and which wraps around the
parent.getDefaultModel().
public class ComponentWrapModelT implements IWrapModelT {
private Component component;
public ComponentWrapModel(Component component) { // component = parent
this.component=component;
}
@Override
public IModel? getWrappedModel() {
return component.getDefaultModel();
}
}
Here's some more background which should explain why I chose to do this:
I replace form components (eg. Textfield) with custom components (eg.
MyTextfield) to add a few things my application needs to them. The name
MyTextfield is a bit misleading here, because this is actually a subclass of
Panel, and it merely contains a Textfield as a child. Still I wanted to use
MyTextfield as a drop-in replacement, even when used in a form with a
CompoundPropertyModel. This is where things got a little tricky, because the
Textfield would end up trying to retrieve a property model matching its own
wicket:id, when the relevant wicket:id had now become that of MyTextfield.
Anyway I would have expected that wicket ensures the parent component model
gets
initialized first, seeing how components generally query their parents when
they
don't have a model of their own. And I'm still considering to report this as
a
bug in Jira.

The child model's initModel() gets called first
There are no especial ordering programing to initModels calls. Basically
they are called by
public final IModel? getDefaultModel()
{
IModel? model = getModelImpl();
// If model is null
if (model == null)
{
// give subclass a chance to lazy-init model
model = initModel();
setModelImpl(model);
}
return model;
}
What about your custom component gain an model that implements
IComponentInheritedModel and assign his children default models with the
desired logic? On IComponentInheritedModel you can access your custom
component parent model, and if you use getDefaultModel method, you don't
need to care with initialization ordering too...

Hi,
I was just trying to create a component of my own which - in some of my
pages -
is created without a model. In the initModel() method I would then call
super.initModel() and wrap the resulting model for use in a child
component. The
problem is the initialization order:
The child model's initModel() gets called first, the parent (my custom
component) does not yet have a model (getModelImpl() returns null) so it
goes up
farther in the component hierarchy and retrieves a wrong model.
Looking at the Component source code (Wicket 1.4.1) I see a commented out
line
where initModel() used to to call the parent getModel() instead of
getModelImpl(). There's also a comment explaining that doing so would
initialize many inbetween completely useless models. Well, not so useless
for
what I am trying to do I guess.
So, from my perspective this looks like a bug that causes necessary
initialization to be bypassed. Obviously though it was done like that on
purpose, so I decided to put the issue up here instead of filing a bug
report.
Has anyone else run into similar issues?
Would it really be so bad to just call getModel()?

Click link lost during self updating
Hello everybody, I've just subscribed to this ml, and even thou I searched past mails about my problem, I couldn't find any hint. I have a page that's refreshing its components every n seconds using AbstractAjaxTimerBehavior. Among these components there's a list of links. If I try to click a link near the refresh interval, the request get lost because of the refresh. One of the solution I'm trying is to disable the refresh on the onMouseDown, and re-enabling it on the onMouseUp event, but this doesn't work as the first event stops forever the ajax method call (the refresh). Every kind of help will be really appreciated :) Thank you in advance Ale

RE: is it possible to somehow create a url to return the contents of a panel
Thank you so much for the response, that was very helpful.
So, I've got half of the equation figured out but now, I have the issue of how
to generate a URL that call a component that allows for a straight HTML
response.
Here is the issue now:
Component someMadeUpAjaxComponent = ... {
onClick(AjaxRequestTarget target) {
// return the component output
}
}
1) Is there a component (the someMadeUpAjaxComponent) that I can get a URL for
which will trigger the onClick method
2) I need to attach the URL for the component to a link - not add the component
directly - is this possible?
3) Given an AjaxRequestTarget, is there any way I can write out the HTML
response (as opposed to adding components for rendering)?
Because, the result will look something like this:
a href={the AJAX URL that will respond with the component HTML content}View
Details/a
I will then attach a tooltip to this link which will know that it can take the
href attribute of the link to obtain the tooltip content.
Thank you very much for any help you could offer.

Re: 1 EAR, 2 WARs causes Spring Context Problem
Thanks Martin! That did the trick. Here's some info for other developers fortunate enough to work with IBM's WebSphere: Firstly, IBM's docs claim that, by default, each application server instance has a WAR class loader policy in which a different class loader is used for each WAR file. This is not true: I checked my local server (installed with Rational Software Architect), dev, QA and prod servers. All of them were set to using a single class loader for all WARs within an enterprise application. I was not asked how to set this policy when I installed RSA on my machine. Secondly, there seems to be a bug that prevents changing the WAR class loader policy when working within RSA. That is, that policy setting was in read only mode when displayed in the WebSphere admin console (aka the Integrated Solutions Console). The solution seems to be as follows: 1) In RSA, double click on the WebSphere 6.1 server displayed in the Servers view; this opens the Server Overview window. 2) In the Server Overview window, go to the Publishing section and uncheck the Minimize application files copied to the server setting. 3) Save the change. 4) Restart the server. 5) Start the admin console. 6) Select an enterprise application, 7) Click Class loading and update detection 8) Set the WAR class loader policy to Class loader for each WAR file in application 9) Apply and save the change. -- View this message in context: http://www.nabble.com/1-EAR%2C-2-WARs-causes-Spring-Context-Problem-tp25684384p25696859.html Sent from the Wicket - User 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: Click link lost during self updating
Ernesto, Thanks for the quick reply, but maybe I haven't explained in an accurate way the problem. Please correct me if I'm wrong; I get that you're suggesting me to disable all the components after the user clicks on a link, and enabling them after the server sends back the response. Is it correct? The problem I'm experiencing is than the first click is lost if the whole page is being refreshed. It seems that the client doesn't send the event to the server; I'm assuming it because our log of the DataRequestCycle doesn't print anythink.

1) Is there a component (the someMadeUpAjaxComponent) that I can get a URL

I don't understand. Is possible to do a lot overriding onComponentTag,
onRender,
3) Given an AjaxRequestTarget, is there any way I can write out the HTML
response (as opposed to adding components for rendering)?
you can append javascript to response...

Thank you so much for the response, that was very helpful.
So, I've got half of the equation figured out but now, I have the issue
of
how to generate a URL that call a component that allows for a straight
HTML
response.
Here is the issue now:
Component someMadeUpAjaxComponent = ... {
onClick(AjaxRequestTarget target) {
// return the component output
}
}
1) Is there a component (the someMadeUpAjaxComponent) that I can get a
URL
for which will trigger the onClick method
2) I need to attach the URL for the component to a link - not add the
component directly - is this possible?
3) Given an AjaxRequestTarget, is there any way I can write out the HTML
response (as opposed to adding components for rendering)?
Because, the result will look something like this:
a href={the AJAX URL that will respond with the component HTML
content}View Details/a
I will then attach a tooltip to this link which will know that it can
take
the href attribute of the link to obtain the tooltip content.
Thank you very much for any help you could offer.

Hi - hopefully I can explain this clearly...
I understand that I can use the AjaxEventBehavior to refresh the

I am trying to use a tooltip to display additional details for grid

I plan to use a tooltip library which supports retrieving content via
an
ajax call. The question is: how (or is it possible at all) can I take
a
Panel and get a url that would return the contents of that Panel. I'm
probably not explaining this well so, here is an example:
AbstractLink link = createLink(IModel rowModel);
Private AbstractLink createLink(IModel rowModel) {

Re: Click link lost during self updating
What I suggested was the other way round... When the page is refreshing block it so that users can't click on a link while that is happening... And the way to block it could be using a veil (e.g. a transparent div layer with a loading icon) that does not allows the user to click on a link (the same as modal windows), not on the server side. I'm not 100% sure but I think wicket chains the AJAX requests so that only one request is processed at a time...(core developers, please correct me if I'm saying something wrong:-(. So, if you click on a link while the page sent a refresh request, then the click will be execute only after page is refreshed... and get lost somehow? There was a thread dealing with a similar situation some time ago... I use a similar approach with a GRID component that allows to drag and drop columns: while table is repainting I block the page so that user can't do anything...

Custom session is null
Hello Wicket Users, I'm a beginner to wicket having previously used Spring MVC and Struts 1/2 so definitely from the other side as far as web frameworks go! Anyway I have a custom session to store a logged-in user; a panel component which performs the login; and a form web page. I'm using Wicket 1.4.1 on Glassfish 2.x and Spring 2.5.6 to hook it all together. I have bookmarkable pages for the login and the form page. Anyway when I deploy the app I go to login. This works fine and I have logger statements when storing the user in the session. Now I go to the form page, which after clicking submit, checks if you're logged in. This test fails and I'm asked to login. If I now do a further login I can return to this form page and it functions as expected. I'm not sure why this session object is null the first time around. If you want me to provide a few code snippets I can. Many thanks Stephen - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

initmodel isnt called until the first getmodel/object call. why would

Can't be done, because the component does not yet know its parent during

You're right, getDefaultModel ensures initialization. I should have
suggested
that instead of getModel (which is not available in the component class
anymore
in 1.4.x).
However, I did not want to override the initModel() method (and copy most
of its
code) just for that. So now I solved it by creating a new wrap model, which
I
pass to the child component and which wraps around the
parent.getDefaultModel().
public class ComponentWrapModelT implements IWrapModelT {
private Component component;
public ComponentWrapModel(Component component) { // component =
parent
this.component=component;
}
�...@override
public IModel? getWrappedModel() {
return component.getDefaultModel();
}
}
Here's some more background which should explain why I chose to do this:
I replace form components (eg. Textfield) with custom components (eg.
MyTextfield) to add a few things my application needs to them. The name
MyTextfield is a bit misleading here, because this is actually a subclass of
Panel, and it merely contains a Textfield as a child. Still I wanted to use
MyTextfield as a drop-in replacement, even when used in a form with a
CompoundPropertyModel. This is where things got a little tricky, because the
Textfield would end up trying to retrieve a property model matching its own
wicket:id, when the relevant wicket:id had now become that of MyTextfield.
Anyway I would have expected that wicket ensures the parent component model
gets
initialized first, seeing how components generally query their parents when
they
don't have a model of their own. And I'm still considering to report this
as a
bug in Jira.

There are no especial ordering programing to initModels calls. Basically
they are called by
public final IModel? getDefaultModel()
{
IModel? model = getModelImpl();
// If model is null
if (model == null)
{
// give subclass a chance to lazy-init model
model = initModel();
setModelImpl(model);
}
return model;
}
What about your custom component gain an model that implements
IComponentInheritedModel and assign his children default models with the
desired logic? On IComponentInheritedModel you can access your custom
component parent model, and if you use getDefaultModel method, you don't
need to care with initialization ordering too...

Hi,
I was just trying to create a component of my own which - in some of my
pages -
is created without a model. In the initModel() method I would then call
super.initModel() and wrap the resulting model for use in a child
component. The
problem is the initialization order:
The child model's initModel() gets called first, the parent (my custom
component) does not yet have a model (getModelImpl() returns null) so it
goes up
farther in the component hierarchy and retrieves a wrong model.
Looking at the Component source code (Wicket 1.4.1) I see a commented out
line
where initModel() used to to call the parent getModel() instead of
getModelImpl(). There's also a comment explaining that doing so would
initialize many inbetween completely useless models. Well, not so
useless
for
what I am trying to do I guess.
So, from my perspective this looks like a bug that causes necessary
initialization to be bypassed. Obviously though it was done like that on
purpose, so I decided to put the issue up here instead of filing a bug
report.
Has anyone else run into similar issues?
Would it really be so bad to just call getModel()?

Re: Click link lost during self updating
Ok, thank you to everyone. I've made further investigation and I (think) can describe the problem: The refresh of the page is set to 3 seconds; The server takes 2 seconds to give the response back to the client; If the user clicks during the 2 seconds interval, the event is lost, and the dialog (or whatever needs to be displayed) doesn't appear. I think that the click is queued to be processed after the refresh is completed, but the page has been changed, and the client doesn't recognize the source of the event anymore. Maybe if I define the ids for each component in the hierarchy, so that wicket doesn't generate them... Do you think this is likely to occur or is just a speculation?

WebMarkupContainer and SimpleAttributeModifier problems on 1.4.1 upgrade.
I've got a little helper method for replacing HTML tag attributes:
public static WebMarkupContainer getContainer(
String name,

String value)
{
//modify check add-on img tag
WebMarkupContainer container = new WebMarkupContainer(name);
container.add(new SimpleAttributeModifier(attribute, value));

Re: Click link lost during self updating
You have to be very careful about what you are doing. Think about the following situation: 1-You have panel A that contains a panel B which in turn contains a check box. 2-Suppose panel B in recreated every time panel A is rendered (e.g. on onBeforeRendered()). 3-The state of the check box depends on a boolean that is set to false on the constructor of panel B. 4-Now suppose the user clicks the checkbox and generates an AJAX request and the boolean is set to true... 5-But right after you have your timer request that repaints A (and recreates B showing an unchecked checkbox). 6-So the effect is that your action of clicking the check box was over-riden by the refresh, I'm not telling this is your situation but if you are not careful many strange things could happen...

Exceptions and Ajax Events
Hi there,Our team was discussing about if there is a place where all exceptions, that come from an ajax behaviour, can be catched. We want to do this because we strongly belive that exceptions should be catched in one place, but now we have to catch the exception in every ajax method( onSubmit, onChance, etc) in the application. Is there one place in wicket where we can do that? Thank in advance. Our team.
Re: Exceptions and Ajax Events
something like this in your application should work:
@Override
public RequestCycle newRequestCycle(Request request, Response response) {
return new WebRequestCycle(this, (WebRequest)request,
(WebResponse)response) {
@Override
public Page onRuntimeException(Page page, RuntimeException e) {
if (RequestCycle.get().getRequestTarget() instanceof
AjaxRequestTarget) {
// do something with ajax request targets
}
return super.onRuntimeException(page, e);
}

AutoCompleteTextField stops showing completions
I'm having trouble with AutoCompleteTextField. It works great most of the time, but occasionally the autocompletions won't show up. This seems to be more of a problem on Safari and IE6. It happens either when the page first renders, or after clicking OK to take action based on the user's selection (there's an ajax button next to my AutoCompleteTextField). I've tried manually reinitializing the autocomplete JS code by calling target.appendJavascript(initialize()). I've also tried re-rendering the AutoCompleteTextField using target.addComponent(field). None of these techniques work. I'm using Wicket 1.4.0. If someone can help, I'd appreciate it. Thanks, Julian

The fact that you've chosen to use Wicket probably shows there's not so

To better see what's going on, try the snippet below in the project you

// append this to your BasePage constructor
con.add(t2.setOutputMarkupId(true));
add(new AjaxLink(toggleVisiblity){
@Override

Fix your BasePage.html accordingly eg, add an anchor to the body with
wicket:id=toggleVisiblity.
When you fire up your app, click on that link once and you can use FireBug
in Firefox to verify that the onblur code you wanted is indeed in place.
Is that the effect you were after?

ModalWindow and LazyLoading Exception
Hi,
I am working with wicket and jpa/hibernate/spring. I am trying to
create a ModalWindow, but I get a LazyLoadingException. I tryed the
OSIVpattern, but it did not work.
Using the modal inside a form does not make any difference also.
Has anyone else this problem?
The page which the modalWindow is triggered has:
===
AjaxLink link = new AjaxLink(openModal) {
@Override
public void onClick(AjaxRequestTarget target) {
modalWindow.setPageCreator(new
ModalWindow.PageCreator() {
public Page createPage() {
return new MyModalPage(modalWindow,
messageListModel.getObject().get(0));
}
});
modalWindow.show(target);
}
};
==
#Modal Panel
==
public class MyModalPage extends WebPage {
@SpringBean
GeneralRepository generalRepository;
SetSubMessage selectedSubs = new HashSetSubMessage();
public MyModalPage(final ModalWindow window, Message message) {
Message showMessage = (Message)
generalRepository.MessagegetById(message.getId(), Message.class);
//showMessage.getLazyList().size();
Form f = new Form(form);
add(f);
CheckBoxMultipleChoice subMessagesCB = new CheckBoxMultipleChoice(
subMessages, new PropertyModel(this,
selectedSubs), showMessage.getLazyList());
f.add(subMessagesCB);
AjaxButton saveButton = new AjaxButton(save) {
@Override
protected void onSubmit(AjaxRequestTarget target, Form? arg1) {
window.close(target);
}
};
f.add(saveButton);
add(new AjaxLink(closeCancel)
{
@Override
public void onClick(AjaxRequestTarget target)
{
window.close(target);
}
});
}

Re: AjaxPagingNavigation
Umm... I apologize. Somebody else wrote this wrapper and I didn't catch that. Thanks!

For example in a different tab or in a new window. This can easily be done in Wicket Framework since the url has a corresponding page attached to it. For example if i get http://localhost/wicket:interface=1 appearing in the address bar, I can open anew tab paste the url and I could get into the same page. The users don't want this behavior. Could I make it work in such a way that I copy http://localhost/wicket:inteface=1, when i try to copy and paste it, it will redirect me to an error page? This happens even after the user has already logged in. Really need help on this one. I've been playing with the ideas from http://day-to-day-stuff.blogspot.com/2008/10/wicket-extreme-consistent-urls.html for something of my own, which might fit the bill in a way. Following that you can convince wicket to serve up every instance of a mounted page from exactly the same URL. That means if you copy the url, you get a brand new instance of the page. You lose the ability to refresh, but if you are being strict on that sort of thing, I guess you will have a refresh button on the page when and only when it is appropriate. -- Phil Housley - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

To: users@wicket.apache.org Date: Monday, September 28, 2009, 9:40 PM Hi, Wicket will render its component based on page relative component path. For an example, a bookmarkable page is requested, then the BookmarkableListenerInterfaceRequestTarget.processEvent() is triggered to lookup the component. But some of the component are only exist when the user session is still available. Then I encounter some component cannot be found due to this condition. Therefore WicketRuntimeException will be thrown. How do I render the page as usual but display label to ask user to sign on for those components are required to sign on instead of exception is thrown.

Immediate need for Wicket developer
Hi All, We have the immediate need for a Wicket developer in the Canton/Akron Ohio, USA area. The candidate needs to be a Senior Java Developer with at least one year of Wicket experience. It would be great if the candidate also has JQuery experience, but any JavaScript/Ajax experience would be welcomed. Thank you!

Re: ModalWindow and LazyLoading Exception
while i couldnt identify which object is throwing the
lazyInitialization, the problem is probably that the entity is not
associated with the hibernate session. On the request that opens the
ModalWindow you must either reload or reatach the entity
