Re: [Wicket-user] Design questions: Use of controllers and wicket models

[David Leangen]

Ok, thanks for the info.

Sorry for not letting this thread die... but one more question (and
hopefully last):

Right now, the page I refactored looks like this:

MyPage page = new MyPage( MyBean bean )
{
   SomeComponent component = new Component( "id", new MyModel( bean ) );
   bla bla
   Hi, Mom
}


So, I'm injecting my bean, as is, into the constructor of the page. The
bean is created somewhere else. In the MyModel above, I'm actually using
a field of a field of the model, so I get:

class MyModel implements IModel
{
  private MyThing thing;

  public MyModel( MyBean bean )
  {
  this.thing = bean.getField().getThing();
  }

  More bla bla
}


So:

Is it "ok" to pass in the raw bean into the page contructor, or should I
be passing in a model instead?

Is there an even better way to go about all this that I haven't noticed?


In any case, what I do really like about IModel is that it gives a
direct translation between the controls and my bean. So cool!


Cheers,
David

Re: [Wicket-user] form processing - getting dropdown selection back to onSubmit method.

[Igor Vaynberg]

once you understand models it becomes quiet trivial :)
below is the simple way (without using a compound property model)

class mypage extends webpage {
private user user;
private logtype logtype;
// getters setters (only necessary in 1.2.x, in later wicket will access
private properties through property model)

public mypage() {
 form form=new form();
 add(new DropDownChoice("users",new PropertyModel(this, "user"),));
 add(new DropDownChoice("logtypes", new PropertyModel(this,
"logtype"),...));

  add(new DataView("results",new MyDataProvider(),...
  ...


 private class MyDataProvider implements IDataProvider {
 public Iterator iterator(int f,int c) {
 return getlogs(user,logtype);
  }
  }
}

and thats all she wrote. makes sense?

Re: [Wicket-user] form processing - getting dropdown selection back to onSubmit method.

 The popilateItem as i know it is used within the dataview. That part i
understand. let me re-explain myself.

on my webpage class, i have a dataview component. i also have a dropdownview
component . they are both children of a form component. i have a beans user,
log and logtype. (I am using wicket along with spring.). now in my webpage
i have a drop down class whic implements dropdownchoice. the list for the

for these two, tie it back to the appropriate bean then set those beans in
the implementation of the dataprovider then use the implementation of the

user selection from the drop down. I can't seem get it without having a

Re: [Wicket-user] Tapestry -> Wicket | Action Service

[Jonathan Locke]

yes.  that and the ability to create new listeners.  there is nothing
special about the listeners that wicket pre-registers to handle various
kinds of requests such as resource requests or link clicks (although you
should definitely prefer the already existing event listeners!).  in fact,
below is the code in init that registers all the "service" listeners in
wicket
revealing that you can create your own if you're doing something special
that wicket does not (yet) support.

/**
 * @see wicket.IInitializer#init(wicket.Application)
 */
public void init(Application application)
{
// Register listener interfaces explicitly (even though they 
implicitly
// register when loaded) because deserialization of an object 
that
// implements an interface does not load the interfaces it 
implements!
IBehaviorListener.INTERFACE.register();
IUnversionedBehaviorListener.INTERFACE.register();
IFormSubmitListener.INTERFACE.register();
ILinkListener.INTERFACE.register();
IOnChangeListener.INTERFACE.register();
IRedirectListener.INTERFACE.register();
IResourceListener.INTERFACE.register();
}

public interface ILinkListener extends IRequestListener
{
/** Listener interface */
public static final RequestListenerInterface INTERFACE = new
RequestListenerInterface(
ILinkListener.class);

/**
 * Called when a link is clicked.
 */
void onLinkClicked();
}

Re: [Wicket-user] Hibernate/Spring and Wicket architecture "request for validation" (was Wicket's questions)

[ZedroS Schwart]

Thanks for your comment Igor, I really appreciate.

Just some questions : do you use CompoundPropertyModel or the detachable one ?

For the form beans, the user profile page I'm working on really proves
you right. I was willing at first to avoid "yet another bean" but in
fact it seems indeed to be the easiest way.

For the optimistic locking, I've read
http://www.hibernate.org/hib_docs/reference/en/html/transactions.html#transactions-optimistic
Is it what you had in mind ?

Thanks again

ZedroS

Re: [Wicket-user] form processing - getting dropdown selection back to onSubmit method.

[GS-ikiini]

I have an implementaion of IDataProvider. that has setters in it and
originally i used it like a model. however the properties have now been
changed to beans. can i still use what you say below? does that populateItem
go into my implementaion of dataView?

in other words, 

Imodel myModelwhichImplementsIDataProvider = new
PropertyModel(item.getModel(),"user")//user is the name of the user property
in myModelwhichImplementsIDataProvider.

Re: [Wicket-user] form processing - getting dropdown selection back to onSubmit method.

[Igor Vaynberg]

first of all the dataprovider is a readonly interface, it has no set method
like the model.

that said what you want is simple:

populateitem(item item) {
  final imodel namemodel=new propertymodel(item.getmodel(), "name");
  add(new dropdownchoice("names",namemodel,nameslist));
}

Re: [Wicket-user] clone object error when open a new window.

[Matej Knopp]

Yeah, this seem to be related to the new wicket object stream code.
Reverting back to DefaultObectStreamFactory fixes it
Objects.setObjectStreamFactory(new
IObjectStreamFactory.DefaultObjectStreamFactory()). Johan, any ideas?

Re: [Wicket-user] HttpSessionStore vs SecondLevelCacheSessionStore(FilePageStore)

[Matej Knopp]

I've got no clue about those exception. There is problem with current
wicket's output stream (it's obvious even in wicket-examples.
Reverting back to default helps here).

But. There is bigger problem than this. The problem with two different
instances of one page. I don't see easy solution for this. Normally,
this is not an issue, because if you keep page instance, you usually
call setResposnePage(instance) to get to it. However, this is not the
case with modal window. So if you keep reference to modal window page,
and then change it's state, it won't help you, because wicket reads
the serialized age anyway.

Re: [Wicket-user] form processing - getting dropdown selection back to onSubmit method.

[Igor Vaynberg]

since you dont specify the model for the selection wicket will look for a
compoundpropertymodel you have somewhere above. the value will go into the
bean that is in the compoundpropertymodel into a property with the same name
as the id of the dropdownchoice.

there is a great page on models on our wiki

Re: [Wicket-user] form processing - getting dropdown selection back to onSubmit method.

[GS-ikiini]

yes i have but i am not quite sure how to apply it to what i am doing. It
calls for a model on which the current selecting is designated thing is in
my selection list i have a strings. but in the model that need setting i
have only mostly bean properties. what i want to do is as the user makes a
selection, i want to take that selection and look up the appropriate bean.
then pass that bean to the model which does something with it. any
suggestions on how to accomplish this?

I'm away from my main computer now, so can't check code, but have you
had a look at the Wicket examples, e.g.

Re: [Wicket-user] HttpSessionStore vs SecondLevelCacheSessionStore(FilePageStore)

[ChuckDeal]

A Page, with a private final ModalWindow reference.

Also, the more I used the ModalWindow in a Tomcat session (between start and
stop of server) the less of the exceptions I see.  In one case where I was
constantly loading the ModalWindow, I stopped getting those exceptions!  I
didn't get the chance to debug it further because my top priority was
figuring out what had changed since the last time my code worked.

Re: [Wicket-user] how do refresh the repeatview after close ajax modal window?

[Matej Knopp]

To refresh a repeater, you have to add it's parent (e.g.
webmarkupcontainer) to ajax request target. Repeater itself has no
markup.

Re: [Wicket-user] Joost uses Wicket

[Ryan]

It is definitely possible. First make sure you are running 1.2.5 or
better (this will fix a bug where posts did not have a '/' after the
context name if you choose to deploy the application with a non root
context). Map your servlet to '/*' ... Next, deploy. =)

The only other issue to worry about is how to serve static content. My
preference is to frontend tomcat or jetty with apache and have apache
serve anything located at /images or /css etc. This means in wicket if
I want to create an image tag that refers to a static image I create a
url that references /images/filename.jpg. When deploying with apache
this will be served by apache and when running without apache I deploy
a static web application to the /images context. This has proven to
work very well for the last few projects I have worked on.

Re: [Wicket-user] Should i upgrade the wicket 2.0 snapshot?

[Eelco Hillenius]

The snapshot works well. As you probably read, we probably will
abandon the constructor change, and will need some time to get a
version up that is like 2.0 but without that feature. In the
meanwhile, 2.0 snapshot should work pretty good. In your case, the
best thing to do is probably create a version yourself by manually
adjusting the version numbers in the pom(s) and creating a release
with maven 2.

[Wicket-user] file upload validation resets form

[Jaime De La Jara]

Hi, I'm using the FileUpload component and set the maxSize property to 150Kb, 
I've 
found that when the uploaded file size is greater than this value, an error 
message is 
displayed (which I customized) but the other fields in the form are emptied. 
How can I fix this situation?

Thanks,

Jaime.

Contrary to what some people say on The Server Side etc, Wicket and
Tapestry are very different frameworks. This means that not everything
can be mapped from one framework to the other. Tapestry's services
seem to be pretty particular for that framework.

The best way to go here is to forget about the facilities you had in
Tapestry, but just focus on what you want to accomplish. It will be
easier for us to help you out with specific use cases, or you might be
able to figure it out yourself.

FYI, I think we had a very short discussion on whether we should have
the concept of services some 2 years ago, but if I remember correctly
we decided against it as we thought it would distract from thinking in
components. That was then though, and it is never to late to hear some
compelling arguments ;)

Re: [Wicket-user] Tapestry -> Wicket | Action Service

[Igor Vaynberg]

you wanted to know how to have an equivalent of a tapestry service. if i
remember correctly tapestry services return things. like an asset service
that streams images.

if all you want is a callback then you can use urlFor methods to build such
a callback url. see, for example, how Link component does it.

wicket is event driven. tapestry is also, but not to the same degree. in
wicket you rarely need to build urls yourself because we provide components
that do this for you.

for example Link has an onClick() method and a Button has onSubmit(). wicket
takes care of wiring these methods with urls it generates.

[Wicket-user] form processing - getting dropdown selection back to onSubmit method.

[GS-ikiini]

hey all,

I am attempting to do some form processing for a filter that i am building.
I user 4 dropDownChoice in a form with a submit button. I want to overide
the onSubmit method, which i did. however when i try to get the values
selected from the drop down in the method for prodessing, they come back
empty. I am using pro wicket as a reference. i wrote simple helper methods
as illustrated in the book but they don't seem to work:


...
desc = new FilterChoice("description",ldp,processTypeDropDownList,logs);
...
 
protected String getDescriptionSelection(){
return desc.getModelObjectAsString();
  }

...
@overide
onSubmit(){
if(MyClass.this.getDescriptionSelection() .equals(something)){
   do something...
}
}

thing is...I insert some log.debugs in there to see what was being returned
and nothing came back. How can i get the selection back to my onSubmit
method i guess is my question. Thank you

-B

There shouldn't be, though SLCSS relies more on serialization then
HttpSessionStore as the latter only uses serialization for the changes
between request (e.g. when you replace a component, it makes a deep
clone of that component so that on a roll back, that component can be
set back) whereas SLCSS serializes the whole pages and stores them on
disk.

>From your description and the fact that it worked earlier for you, I
suspect the custom serialization we are building into Wicket and which
is currently the default is at fault. To set that back you can call:

Objects.setObjectStreamFactory(new
IObjectStreamFactory.DefaultObjectStreamFactory());

in your application#init method. Custom serialization can be turned on
again by calling:

Objects.setObjectStreamFactory(new WicketObjectStreamFactory());

Note that the naming is a bit weird maybe, as the
DefaultObjectStreamFactory is not the default :) Interpret this as a
factory for JDK's default object streams.

wicket's equivalent of a service is a shared resource. you can register your
own shared resources through your webapplication subclass.

as far as selecting pages via javascript:

wicket doesnt really have a page service. urls for pages are resolved
internally. if you want a stable entry point into the page then you should
mount it, also via the webapplication subclass, and then the javascript can

Re: [Wicket-user] AjaxFallbackLink and ListView

[Igor Vaynberg]

there is a bug in 1.2.5 with header contributors. what happens is that
wicket-ajax.js file doesnt get included in the rendered page and so the link
goes into fallback mode.

this is fixed in wicket-1.2.x branch which you can check out and build, or
wait for 1.2.6 release

Hi,

I found out that in some cases AjaxFallbackLinks creates a normal call
(AjaxRequestTarget == null) in onClick instead of an ajax call.

In my example case there is a (submit)Button that puts some stuff on
Vector which is shown in a ListView below. If following process is done,
the AjaxRequestTarget is null in onClick:
- press Submit test
- press some link in the list (let's say Open 2)
- press Submit test again
- press Open 2 again

Why does this happen?

I am using wicket 1.2.5 and the example can be found on:

Re: [Wicket-user] HttpSessionStore vs SecondLevelCacheSessionStore(FilePageStore)

[ChuckDeal]

Sorry, I posted this too soon.  more details...

Wicket 1.3 (revision 518581)
I know that the code was working correctly with the SecLvlCacheStore as
recently as the week of  01MAR2007 - 07MAR2007 if not even a few days after
that.

[Wicket-user] HttpSessionStore vs SecondLevelCacheSessionStore(FilePageStore)

[ChuckDeal]

I need some help tracking down a problem with the
SecondLevelCacheSessionStore/FilePageStore.  I think the problem is there
because when I switched to the HttpSessionStore, it went away.  That only
took me 5 or 6 hours to figure out...arghh

Anyway, my scenario is this:
I have a Page that contains an enhanced ModalWindow (I added a couple of
methods to return state info; which button was clicked, what is the return
value Object is).  The actual operation of the ModalWindow appears to be
fine.  When I click one of the buttons on my Page (ie a CANCEL button that
sets the button state to CANCEL and returnValue=null, then closes the
ModalWindow), I can see that the state info is stored in the correct fields
on the corrent *instance* of the ModalWindow object.  But, by the time the
ModalWindow.WindowClosedCallback.onClose() method fires, I have a handle to
the wrong *instance* of the ModalWindow!  We're talking the actual
ModalWindow Component instance has changed (I verify this in the debugger by
looking at the Java Object id).

I'm dumbfounded, I couldn't imagine how that could happen, then I remembered
all the talk about serialization and such, so just for fun, I overrode the
newSessionStore() method of my Application to return new HttpSessionStore()
and sonofabitch if the same code didn't work this time.

Can someone offer me some guidance on how to verify that the
SecLvlCahce/FilePageStore is actually the culprit?  Can I provide some
debugging info/log output that would be of use to a Wicket dev in tracking
it down?  Mind you, I'm not getting anything in my logs that says there is a
problem, it just isn't working...

Is there a big difference in using HttpSessionStore instead of the
SecLvlCacheStore in the mean time?

Thanks
Chuck

Re: [Wicket-user] how do I set Ajax time out[wicket 1.2.4]?

Hmm this is really wierd, when testing this against one of our dev machine's 
these errors does not occur.. It only occurs against our servers.

Emne: [Wicket-user] how do I set Ajax time out[wicket 1.2.4]?



Hi

I have some components that uses the ajaxformupdatingbehavior. Some times(1% of 
1300 requests) under "heavy" load(24 concurent users/threads using jmeter) some 
of them fails to be able to select something in the dropdown thats using the 
updating behavior. This leads me to think that the ajax updating behavior times 
out, so how do I increase the duration on ajaxrequests?

[Wicket-user] Testing repeaters

[Daniele Dellafiore]

Hi. I am trying to make a test to check the content of a DataTable
that is in a WebPage.
I can get the table with page.get("table");
where "table" is of course the path to my table component in the page.

How can I access a cell in the table? What is the path for, say, cell 1,1?
Or there are other way using tester?

Till now I am using httpunit to test tables but I would like to test
the wicket component by itself and, more over, the WebPage stays in a
Modal Window and I do not know how to test a page in a modal window
via httpunit.

PS: also to know how to test a model window would be very useful.

 Thanks.

[Wicket-user] Tapestry -> Wicket | Action Service

[Robert .]

Hi,

I have been examining how I can convert a web application product from
Tapestry 3 to Wicket, and trying to adapt
myself to the Wicket way of thinking about web flow.

One part that I just can't seem to figure out from reading Pro Wicket and
browsing through the apidocs is how to
make something like Tapestry "services".

For example I have an action service in Tapestry that let's me send an
action command, including additonal parameters,
to the service by using javascript. I have such a service for both normal
requests and XMLHTTP requests. But thinking
about this further makes me realize I don't even know how to make something
like a PageService where the page is determined by javascript.

I feel like I am missing something.

[Wicket-user] AjaxFallbackLink and ListView

[Juha Alatalo]

Hi,

I found out that in some cases AjaxFallbackLinks creates a normal call 
(AjaxRequestTarget == null) in onClick instead of an ajax call.

In my example case there is a (submit)Button that puts some stuff on 
Vector which is shown in a ListView below. If following process is done, 
the AjaxRequestTarget is null in onClick:
- press Submit test
- press some link in the list (let's say Open 2)
- press Submit test again
- press Open 2 again

Why does this happen?

I am using wicket 1.2.5 and the example can be found on:
https://download.syncrontech.com/public/wicket-ajax-fallback.zip

Re: [Wicket-user] Converters

[Anders Peterson]

When I read some old posts discussing changes to the converts I thought 
you where trying to re-invent Format. All that would be required is a 
factory/cache that finds/builds the correct instance and perhaps some 
new Format subclasses.

If you can code MyOwnBigDecimal, then my would it be impossible to code 
a MyOwnFormat and register it with the factory/cache?

I don't know how the new converters work - I'm sure they're great. I 
look forward to the next new release!

Re: [Wicket-user] Package rename heads-up for wicket-1.x branch

[Gwyn Evans]

On 15/03/07, Al Maw <[EMAIL PROTECTED]> wrote:

As part of our ongoing incubation process at Apache, we're going to be
renaming the core wicket package from "wicket" to "org.apache.wicket"
shortly (not quite sure when yet, but soon).

If you're developing against the subversion wicket-1.x branch, you'll
need to change your imports accordingly.


And possible web.xml & Javadocs (e.g. @see
wicket.model.IModel#getNestedModel())


If someone feels like telling IDEA/NetBeans/ other IDE users how best to
accomplish this, by all means tell us. :-)


With IDEA, the best way is probably "Refactor/Migrate" then "New..."
then "Add" a "Package" mapping from "wicket" to "org.apache.wicket".
Give it a name, e.g. "Wicket to Apache Wicket" then run it - you'll be
able to preview/exclude the changes as normal.

(If the attatchment comes through, just drop it in your IDEA's
config\migration\ folder to have the mapping setup for you, but it's
no big deal if it doesn't.)

You'll need to exclude the wicket.contrib manually (or just run it
then migrate org.apache.wicket.contrib back to wicket.contrib)!

Re: [Wicket-user] How to attach thread

[Martijn Dashorst]

You can still do that, but you need to reverse the logic: query the
running thread for the required progress/data instead of pushing it
from the thread to the session.

The difference between Swing apps and web apps is that you can run the
web app on multiple machines, where the session is shared between
different servers.

Another thing is that the session is managed by the web container, and
can be serialized to disk or a database. Keeping (unmanaged)
references to managed objects is not a wise thing to do.

"Don't call us, we call you" is a good principle in this case.

Re: [Wicket-user] How to attach thread

[Thomas Kuechenthal]

But how for example will it then be possible to run time intensive
functions while updating the process status within the gui?
I think in a MVC or event driven environment it must be possible to
completly seperate the business logic from the gui.
In Swing for example it is the usual way to put time intensive actions
into an own thread. e.g. time consuming database queries of which the
results shall be displayed after a while, without freezing the whole gui.
