wicket-ajax.js (revision 518211) appears to have a problem.
I think lines 296-299 should be
var e = element.childNodes[i];
if (e.tagName != null) {
result += Wicket.Form.serialize(e);
}
but right now they are
var e = element.childNodes[i] {
if (e.tagName != null) {
result += Wicket.Form.serialize(e);
}
}

Re: [Wicket-user] Design questions: Use of controllers and wicket models
Hi,
(If Igor says anything different, just ignore this! :-))
The change that I'd consider would the standard one of if it'd be
worth passing in a custom IMyBean interface derived from IModel, to
cover the case where I might want to use something like-but-not-a
MyBean, but I can't see anything wrong with passing it directly if
that's not the case.

a field of a field of the model, so I get:

this.thing = bean.getField().getThing();

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!

Ok, let's stick with the person object. The

For example:
Person:

else

[ ] walks dog?
Whatever.

goes if
isSingle is false.
Right now, I collect a boolean for each value and

Same thing for enabling/disabling my checkboxes

What I'd really like to do is somehow bind all

Any hints that would enlighten me on how to do
this?

Re: [Wicket-user] Tapestry - Wicket | Action Service
Hi! A Tapestry service basically has a public void service(RequestCycle) method. Something like a PageService would do something like cycle.activate(cycleparam[0]) Now I understand that I don't usually need a PageService. The onClick for Link components are much easier to use. However what if I don't have a component and there is some javascript that wants to change the page? I'll try to write about this more in the other replies in this thread.

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. Yes, I have noticed that :) Tapestry's services seem to be pretty particular for that framework. And without those services there is not much left in Tapestry. 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. What I need is a way to do have a call from javascript to trigger some action. Both through normal HTTP requests and XMLHTTP, but I will focus on the normal part first. There is no associated component in the page. It is just a javascript controller object, that wants to send commands to my application. The request cycle is enough for me to continue at that point. Something else related to this is if I can have a Link where I can add parameters to in javascript. Looking at Wicket I get the feeling that the state is purely something that is kept in pages and components with its associated models. There does not seem to be room for the client browser to keep any state. I actually have a whole model-view-controller system in javascript for certain complicated situations. I tried to look at how a Tree component works, and see if I could learn something by looking at how it's called. But that part was just magic to me :) Robert - Take Surveys. Earn Cash.

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] Tapestry - Wicket | Action Service
I tried to look at those listeners. If I understand correctly you always
need to be a component to be a listener.
Each listener interface must have 1 method with 0 parameters. So it means
all state must be kept in the component.
You cannot pass any parameters to it? So in the case of a PageLink you must
know which page to render, before
the link has been clicked?
I'm just trying to sort things out in my head.
I would like to know more about how Wicket knows which ILinkListener to call
when a link is clicked. I found the apidocs
to be rather abstract about listeners. It felt like you already had to know
how they work before you can understand the docs.
Please don't take any off this as criticism against Wicket. I'm sure it is a
great project. And I will be using it in the future.
I'm just not sure if I should convert this project from Tapestry to Wicket.
I am beginning to think that it's not a good idea.

Re: [Wicket-user] Tapestry - Wicket | Action Service
Each component is unique in the hierarchy. The link listeners get a
session/page/version relative url that instructs Wicket to retrieve
the correct page/version from the pagemaps. This is the :0:1:2:3 part.
So it is possible to have a form that is a form submit listener, an
ILinkListener, or some other registered event.
The request parameters are available in the WebRequest, so you should
be able to get them. They just aren't passed on to the listener
interface directly.
This is one of the area's where Wicket wasn't designed for. It is
possible to accomplish, but not as elegantly as using components.

If you use Tomcat then there is a special ROOT configure directive (or Path - sorry here, but havent had to do with it for long time) wich can be found in the Tomcat-Docs (similar is jetty - just look for context root or context path) if you use a real appserver e.g: SJAS you really want to go over the EAR or WAR way and define the Context-Path to be / in the container-web.xml (SJAS: sun-web.xml) e.g: context-root//context-root in the web.xml itself you only need to map it to /* (dont forget the *) e.g: filter-nameNAME/filter-name filter-classwicket.protocol.http.WicketFilter/filter-class init-param param-nameapplicationClassName/param-name param-valueYOURAPPCLASS/param-value /init-param init-param param-namefilterPath/param-name param-value/ filter-mapping filter-nameNAME/filter-name url-pattern/*/url-pattern /filter-mapping so you then can configure it the way you want: domain.com/context_name/filterpath ^container ^web.xml Regards, Korbinian -Ursprüngliche Nachricht- Von: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Im Auftrag von tooy li(Gmail) Gesendet: Freitag, 16.

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] form processing - getting dropdown selection back to onSubmit method.
the id of dropdowns has nothing to do with their model. i am not using a
compound property model anywhere in the code, nor am i not specifying it
directly.
the model for each dropdown is specified as a propertymodel where this
refers to the page and the string refers to the property on that page.
so the selected user object will go into the user page property, and the
selected logtype will go into the page's logtype property just like the
property models specify.
then your dataprovider picks up those two properties and uses them to filter
the result just like the code shows.
the models are just glue between formcomponent and properties on some java
bean - which in this case happens to be the page.

Re: [Wicket-user] Tapestry - Wicket | Action Service
Please don't take any off this as criticism against Wicket. I'm sure it is a great project. And I will be using it in the future. I'm just not sure if I should convert this project from Tapestry to Wicket. I am beginning to think that it's not a good idea. Imo, you always need a very good reason to convert your projects from one technology to another to start with. It has to solve something for you, and it has to be worth more than the pain you will inevitably be going through. You know, the old if it aint broken, don't fix it. Eelco - Take Surveys. Earn Cash.

It could be useful in situation where UI components are not mapped to Wicket components, but you wants access to page state. For example just think about a javascript input dialog.

Re: [Wicket-user] form processing - getting dropdown selection back to onSubmit method.
first the properties are on the page, not on the dataprovider. since
dataprovider is an inner non-static class it has access to page properties.
second - the particular user object or logtype will come from the dropdown.
you give the dropdown a list of users and logtypes you said earlier no?
dropdowns work like this
DropDownT(String id, IModelT, IModelListT, IChoiceRendererT)
so you give it a list of objects and it will push the selected object into
the model.
if all you are giving it is a list of strings then the selected object will
also be of type string.

the model for each dropdown is specified as a propertymodel where this

so the selected user object will go into the user page property, and
the
selected logtype will go into the page's logtype property just like
the
property models specify.
then your dataprovider picks up those two properties and uses them to
filter
the result just like the code shows.
the models are just glue between formcomponent and properties on some

Re: [Wicket-user] Tapestry - Wicket | Action Service
Here is a super-simple example of creating a custom request listener.
First, you create the new listener interface:
public interface IHelloListener extends IRequestListener
{
public static final RequestListenerInterface INTERFACE = new
RequestListenerInterface(
IHelloListener.class);
void onHello();
}
Note that it has a single method without parameters. This is a
requirement as you can read from IRequestListener's JavaDocs. The
other thing to note is the INTERFACE field; by instantiating a
RequestListenerInterface you register the interface, and the field
exposes a handle for constructing URLs using RequestCycle's UrlFor
methods.
Next, I simple patched the HelloWorld example like this:
public class HelloWorld extends WicketExamplePage implements IHelloListener
{
public HelloWorld()
{
add(new Label(message, Hello World!));
WebMarkupContainer link = new WebMarkupContainer(link);
link.add(new SimpleAttributeModifier(href,
RequestCycle.get().urlFor(this,
IHelloListener.INTERFACE)));
add(link);
}
public void onHello()
{
RequestCycle.get().setRequestTarget(new IRequestTarget()
{
public void detach(RequestCycle requestCycle)
{
}
public void respond(RequestCycle requestCycle)
{
requestCycle.getResponse().write(htmlbodyHELLO!/body/html);
}
});
}
}
The html is straightforward, with the link defined like: a
wicket:id=linkclick me/a
And that's all there is to it: we created a new kind of listener for requests.
Note that it is (still) bound to a page (or any arbitrary component).
It is entirely possible to decouple this further, from the top of my
head by providing a custom WebRequestCodingStrategy and override
doEncode for your specific purpose. But if you are doing that, you
probably might as well just create your own servlet.
It is certainly a design goal for Wicket to be very extensible.
However, it is *also* a goal to have different levels in our
abstraction. I agree with Igor that having services so upfront in the
architecture is or at least encourages scope creep, as it makes it too
obvious for users to start coding their own as if they were a
replacement for servlets and don't take the time to fully get into the
component mind set. As you can see from the example, there are pretty
much no limits to what you can do with Wicket, but we hope that doing
things like creating custom listeners are only used as a last resort.
And if you think you find a really good use, we'd appreciate it if you
would communicate it as there might be something we missed and can
result in a useful addition to Wicket.
My 2c, and again, if you have good and specific use cases, share them :)

Re: [Wicket-user] Tapestry - Wicket | Action Service
Easiest way to call a wicket method from javascript is imho to extends
AbstractDefaultAjaxBehavior - implement the respond() method, call
getCallbackScript() to obtain javascript that needs to be executed to
call the respond() method. The behavior must be added to a component
(or page, as page itself is also a component).

Re: [Wicket-user] Tapestry - Wicket | Action Service
Wicket == component-oriented manipulation of markup. As such, Wicket is primarily a UI framework, not a framework for creating web services. Igor is right that this idea that Wicket should handle any kind of request over HTTP is scope creep. That job is for some other framework. Robert ... wrote: Hi! A Tapestry service basically has a public void service(RequestCycle) method. Something like a PageService would do something like cycle.activate(cycleparam[0]) Now I understand that I don't usually need a PageService. The onClick for Link components are much easier to use. However what if I don't have a component and there is some javascript that wants to change the page? I'll try to write about this more in the other replies in this thread. Robert On 3/15/07, Igor Vaynberg [EMAIL PROTECTED] wrote: 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. -igor On 3/15/07, Robert .

Re: [Wicket-user] Tapestry - Wicket | Action Service
yes, state is mainly kept in server side components by design (programming model and security are two good reasons for this). however, state can also reside in url parameters (bookmarkable page links) if you explicitly put it there. and then of course there's javascript / ajax. Robert ... wrote: Something else related to this is if I can have a Link where I can add parameters to in javascript. Looking at Wicket I get the feeling that the state is purely something that is kept in pages and components with its associated models. There does not seem to be room for the client browser to keep any state. I actually have a whole model-view-controller system in javascript for certain complicated situations. I tried to look at how a Tree component works, and see if I could learn something by looking at how it's called. But that part was just magic to me :) Robert -- View this message in context: http://www.nabble.com/Tapestry--%3E-Wicket-%7C-Action-Service-tf3408177.html#a9521396 Sent from the Wicket - User mailing list archive at Nabble.com. - Take Surveys.

Re: [Wicket-user] Tapestry - Wicket | Action Service
yes. and that design was not accidental. in a framework, making
some things harder is as important as making other things easier.
for example, we could have provided easy access to the HttpSession.
there are people who do need access to that. but it gives people the
wrong idea about how to do things in wicket.
more is not necessarily better. and i think that's true here. more
support for client state and/or better support for generic web services
would actually move people in the wrong direction in terms of wicket's
stated goal to provide component-oriented manipulation of markup.

I tried to look at those listeners. If I understand correctly you always
need to be a component to be a listener.
Each listener interface must have 1 method with 0 parameters. So it means
all state must be kept in the component.
You cannot pass any parameters to it? So in the case of a PageLink you
must
know which page to render, before
the link has been clicked?
I'm just trying to sort things out in my head.
I would like to know more about how Wicket knows which ILinkListener to
call
when a link is clicked. I found the apidocs
to be rather abstract about listeners. It felt like you already had to
know
how they work before you can understand the docs.
Please don't take any off this as criticism against Wicket. I'm sure it
is a
great project. And I will be using it in the future.
I'm just not sure if I should convert this project from Tapestry to
Wicket.
I am beginning to think that it's not a good idea.
