image inside wicket:link tag

[Gatos]

Hello,


   ID
 

When I click the link then image is shown. For some reason src="img/id.gif"
interpretates as a link.
How to solve the problem?
Wicket 1.4.1

Thank you

Can Wicket automatically remove beginning and trailing spaces in a text field?

[David Chang]

How to set it up in a Wicket application? I would like to set it up in the 
application level.

Thanks!

Re: ModalWindow and LazyLoading Exception

[Marcelo Fukushima]

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

Immediate need for Wicket developer

[Eric Glass]

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!

 We have this requirement in which we cannot allow the customer to

 The users don't want this behavior. Could I make it work in such

 that I copy http://localhost/wicket:inteface=1, when i try to

 If your url is getting replaced, then it isn't using ajax.
 It is redrawing the page.

ModalWindow and LazyLoading Exception

[Albert Romanius]

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;

Set selectedSubs = new HashSet();

public MyModalPage(final ModalWindow window, Message message) {

Message showMessage = (Message)
generalRepository.getById(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: WebMarkupContainer and SimpleAttributeModifier problems on 1.4.1 upgrade.

It was a classpath issue - you had an old version of Wicket somewhere.  1.3
/ 1.4 are not binary compatible.  Perhaps even in a serialized session?

Re: Exceptions and Ajax Events

[Esteban Masoero]

Hi:

We found out we need something else. Is there a way we can access to the 
component asociated to the listener that was processing the event? (of 
course it only applies to ajax events), becase from onRuntimeException 
we ony have the Page.


Thanks,

Esteban

Hi there,Our team was discussing about if there is a place where all

We want to do this because we strongly belive that exceptions should be

ajax method( onSubmit, onChance, etc) in the application.
Is there one place in wicket where we can do that?

Thank in advance.

Refresh the page is default link behavior, you may want to use AjaxLink to
avoid it

Doubt with Link

[Pedro Sena]

Hi Guys,

First of all, sorry for a so newbie question, but I'm really a newbie in
Wicket.

I'm trying to add a Behaviou to my link, it works fine with
link.add(myBehaviourHere)

I'd like to know how to avoid any page redirect the link does. I left
onClick without code but it redirects to the page that I'm actually(expected
behavior)

Any tips?

AutoCompleteTextField stops showing completions

[Julian Sinai]

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

Exceptions and Ajax Events

[Nicolas Melendez]

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: Click link lost during self updating

[Ernesto Reinaldo Barreiro]

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...

Best,

Ernesto

WebMarkupContainer and SimpleAttributeModifier problems on 1.4.1 upgrade.

[VGJ]

I've got a little helper method for replacing HTML tag attributes:

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

return container;
}

I just upgraded from 1.3.2 to 1.4.1, and I'm getting this exception every
time the above method calls the "add" method:

"java.lang.NoSuchMethodError:
org.apache.wicket.markup.html.WebMarkupContainer.add(Lorg/apache/wicket/behavior/IBehavior;)Lorg/apache/wicket/Component;"

I just looked at the 1.4 Javadocs...it looks like this is still valid.  What
am I doing wrong?

Thanks!

Sure, I'm aware of how cookies work but there shouldn't be a  
difference, in terms of whether a cookie is sent, from clicking a link  
to typing in a url. So long as the domain matches that of the cookie  
it will be sent every request.


So I'm not sure of the difference between accessing the page directly,  
or accessing the page through a link. My session should be retrieved  
on each request. This is what I'm not understanding I feel.

server, that now can to know with what session he has to work.

Re: Click link lost during self updating

[Alessandro Novarini]

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? Any of you
had a similar experience?

I'm reading the links in the meantime.

Thanks again

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

 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...

models from component parents

[Troy Cauble]

If this works

Panel  // no explicit model
   WebMarkupContainer  // no explicit model
  RefreshingView (listModel)

should this?

Panel (listModel)
   WebMarkupContainer  // no explicit model
  RefreshingView  // no explicit model

RefreshingView#getModelObject() returns null.
I thought it would get the list.
The LDM#load is not being called.

Any ideas?
Thanks,

Hi Pedro,

Thanks for the reply. You are correct - I just added a link component  
on my login page to my form page and it now functions as expected.


However I don't quite follow why it doesn't work when manually typing  
a url in. If I'm logged-in I would expect to stay logged-in whether I  
manually type a url or follow a link. Which bit am I misunderstanding?

Custom session is null

[Stephen Nelson]

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

Re: Click link lost during self updating

[Ernesto Reinaldo Barreiro]

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... I do the same for ajax links, etc.

Best,

Ernesto

java.lang.StackOverflowError and ModalWindow

[Altuğ B . Altıntaş]

Hi all;

I have a modal window; In that modal window i put a flash upload tool which

couldn't understand this issue.

Re: is it possible to somehow create a url to return the contents of a panel

[Pedro Santos]

1) I just want to return straight HTML (not contents within the
 node)

return to where? to broser?
target.appendjavascript("document.body.innerHTML = '"+resultHTML);

how I could show a dynamic tooltip with data retrieved using ajax?

target.appendjavascript("Wicket.$('"+myLabelComp.getMarkupId()+"').alt = '"+
myNewTooltip+"'");
( alt or title... any tag attribute you need to change)

Re: Click link lost during self updating

[Alessandro Novarini]

Pedro,

Thank you.

This is indeed a solution, but it would mean rewriting the whole
application. There are lots of components that need to be refreshed, and
adding to each of them the behavior don't seem trivial.

I'll give it a try anyway.

Thank you
Ale

RE: is it possible to somehow create a url to return the contents of a panel

[Joe Hudson]

So, it is looking like I could do something like this:

Link link = new AjaxLink(componentId, new 
Model("View Details")) {
@Override
public void onClick(AjaxRequestTarget target) {
String resultHTML = convertPanelToHTML();  // I 
understand this

// how can I override the target response with the 
result HTML?
}
};

1) I just want to return straight HTML (not contents within the  
node)
2) I need the link to return the contents directly (not handle the contents 
with the Wicket ajax javascript code)

Is type of behavior possible?  If not, does anyone have any other ideas as to 
how I could show a dynamic tooltip with data retrieved using ajax?  Thank you 
very much.

Joe

Re: Click link lost during self updating

[Alessandro Novarini]

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.

Thanks you again
Ale

Re: 1 EAR, 2 WARs causes Spring Context Problem

[shetc]

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.

RE: is it possible to somehow create a url to return the contents of a panel

[Joe Hudson]

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:
View 
Details

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.

Joe

Re: Click link lost during self updating

I have a page that's refreshing its components every n seconds using

Among these components there's a list of links.

Would be nice if you apply AbstractAjaxTimerBehavior only to components that
need to be updated. Than you don't get in trouble with your links...

Hi Douglas,
you extend the AjaxPagingNavigator and override his method newNavigation to

Click link lost during self updating

[Alessandro Novarini]

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: Component initModel() order (design issue?)

[Edmund Urbani]

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.

Cheers
 Edmund

 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()?

  Edmund
