Re: [Wicket-user] Best practice for mapping objects to ids
Interesting. The SimpleSelection can be used on any DropDownChoice, this
is nice. I extended DropDownChoice for all the cases where I want to
specify the choices directly:
public static class SimpleDropDownChoice extends DropDownChoice {
private static class Choice {
private String label;
private Object value;
public Choice(String choiceLabel, Object choiceValue) {
label = choiceLabel;
value = choiceValue;
}
public String getLabel() {
return label;
}
public Object getValue() {
return value;
}
}
public SimpleDropDownChoice(String id, IModel model) {
this(id);
setModel(model);
}
public SimpleDropDownChoice(String id) {
super(id);
setChoiceRenderer(new IChoiceRenderer() {
public String getDisplayValue(Object object) {
Choice e = (Choice) object;
return e.getLabel();
}
public String getIdValue(Object object, int index) {
return String.valueOf(index);
}
});
setChoices(new ArrayList());
}
public SimpleDropDownChoice addChoice(String label, Object value) {
List choices = getChoices();
choices.add(new Choice(label, value));
setChoices(choices);
return this;
}
}
Usage:
SimpleDropDownChoice c = new SimpleDropDownChoice(gender);
c.addChoice(Male, new Integer(1));
c.addChoice(Female, new Integer(2));
c.addChoice(Unisex, new Integer(3));

Matej Knopp schrieb:
It's doable, but you have to write your own choice renderer.
I've made a SimpleSelection class that might help you. Usage is
SimpleSelectionItem items[] = {
new SimpleSelectionItem(1, Male),
new SimpleSelectionItem(2, Female),
new SimpleSelectionItem(4, Unisex)
};
SimpleSelection selection = new SimpleSelection(items);
add(new DropDownChoice(gender,

if you want to map that then the fastest way that i can think of right

a model that sits between it. That maps CategoryVO - int back and
forward.
Why do you work with ints in the model objects? Why not just full

Re: [Wicket-user] started working on 2.0 and migration doc
Eelco Hillenius schrieb:
We're hoping for you help, and of course we hope that you'll like Wicket
2.0
I wasn't convinced by the constructor change at first for two reasons:
- Requiring a constructor can be very limiting for clients of the API
- add() seems to be a very intuitive method for adding children to a
component
After thinking about the impact that this change would have on the
actual code I am writing, I changed my opinion. Quite often, I have code
fragments that look similar to your example in the wiki article:
MyLink link = new MyLink(link);
add(link);
link.add(new Label(myLabel, myText));
The Wicket 2.0 version is much more streamlined:
MyLink link = new MyLink(this, link);
new Label(link, myLabel, myText);
One thing that came into my mind regards the use of repeaters. Instead
of requiring this not very intuitive code:
Repeater r = ...
r.add(new Label(r, r.newChildId()));
It would be possible to let the child acquire it's ID from the parent:
class Label {
Label(Repeater parent) {
super(parent, parent.newChildId());
}
}
Resulting in a nicer usage:
Repeater r = ...
r.add(new Label(r));
I am not sure about the impact, but it looks nice from my naive
perspective.
Regarding the use of Generics for IModel and Components, I think that
it's a perfect fit. So, yes, I think I'm going to like 2.0 :)
Where do you need help, and how should that work? I would imagine that
it wouldn't help much if everyone bombards you with incompatible patches.

*Subject:* Re: [Wicket-user] Border and markup inheritance problem
if you look at the hierarchy of your message label it is like this:
in java:
page-message
in markup:
page-border-message
so when wicket tries to render message in the markup it cannot find it
because it expects it to be in the border, but in fact you have added
it to
the page itself in extendpage.
so what you should do is either someting like this
ExtendPage() { getBorder().add(message); } to put it in the right place
or
BasPage() { add(new MyBorder(blah).setTransparentResolver(true); } this
will tell wicket that the border is transparent - if component inside
border
cannot be found wicket should try to locate it in the border's parent
or use markup inheritance which is a much much better fit for this
usecase

smallufo schrieb: Google Web Toolkit - Build AJAX apps in the Java language released on 5/16/2006 http://code.google.com/webtoolkit/ It seems powerful and slick Had a quick look at it. It is a small but complete framework. Everything is written in Java, even the GUI components, which are compiled into Javascript+HTML. There is a remote procedure call interface that allows arbitrary serializable java objects to be sent to the client, even exceptions. I can't say much on the Java to Javascript+HTML compiler, but it doesn't seem to be such a good idea. Java 1.5 is not supported, and the rich set of java libraries can't be used. It's certainly an intriguing idea (have a look at haxe.org if you find it interesting), but I don't really believe in this concept. It is very difficult to abstrahize the features (or should I say quirks) of different browsers. Some months ago, I had a look at several javascript libraries and it worked pretty flawless in every browser. When I checked again this week, one browser simply crashed. On 2 of 4 pages. It's sad, but it's just not stable enough for me. The GWT demo site worked fine, but custom components will be very tedious to develop and maintain. Another issue is previewability. Not just for a designer, but for debugging purposes. If you click view source in your browser on a GWT page, you will see nothing but a HTML skeleton and an iframe. Anybody has any idea to integrate it to wicket ? Integration into wicket doesn't seem feasible to me. It might be possible to integrate GWT widgets into a wicket page, but I think it makes more sense to use wicket components in combination with a client side ui library like the yahoo ui library. The effect will be the same, but you only have one type of component to take care of. But I don't know if wickets AJAX support is good enough yet. Timo --- Using Tomcat but need to do more?

Re: [Wicket-user] URL redirect
Thomas, you are using a proxy, right? If you enter http://localhost:8080/foo/ in the browser, wicket redirects to http://localhost:8080/foo/?page=0 But with the proxy in between, the browser is redirected to http://localhost:8080/foo?page=0 I have experienced this problem with mod_prox, and I don't have a solution. I hope to be able to fix it when going to 1.2. which seems allows more control over URLs. IMHO wicket should allow full control over rendering of URLs and never rely on the servlet container to complete redirect URLs. This would make working with proxies a lot easier.

Re: [Wicket-user] Re: The other side of Wicket ...
Hi Ashley, only some points answered, but maybe the answers are helpful. Ashley Aitken schrieb: Clone by serialisation? I guess you mean you serialise and then un/de-serialise. So you don't serialise to save to disk? Java has no deep-copy mechanism. Serialization can be used as a workaround. I don't think the back button can be equivalent to an undo type operation? It actually is with Wicket. Of course you have to decide when you commit data. For example you can't undo a sent E-Mail. i think you misunderstand what the model is. the model is the databinding. it allows the component to retrieve and store data in an abstract way. Sorry if I am not getting this. I thought a model could be a simple String, or a more complex object (or small object graph) like Customer. I thought most components were associated with a model, i.e. the object(s) that they are representing in some way in their view. A databinding, for me at least, would be a mapping between parts of the view and parts of the model but *not* the model itself, an associative map of some kind. That said, I think I know what you mean and there is no need to argue over definition. The terminology of Wicket is a bit imprecise. IModel is the glue. Model objects (IModel#getObject()) are the model. the extra work with models gives you the backbutton support, something that almost no other framework that stores state in session does. As above, personally speaking, I am not sure this is a high priority feature for Web 2.0 applications. But, of course, these are only one type of Web applications, and perhaps not a focus of Wicket. It is a high priority feature of stateful web frameworks. Without that, the back button would behave unexpectedly. well, wicket is perfect for the heavily stateful applications imho. i think the best way to learn would be to write a small application in the prod like environment. see where the challenges are, and we will try to help you along the way. prod = productivity? Production environment. Solving real problems instead of theoretical ones. Thanks for the offer and I may just be doing that. To be honest though, I am still tossing up between Wicket and Echo2 (or even something more standard). Echo2 is, to me at least, very Web 2.0 focussed. Quite frankly, Echo sucks. I evaluated it (and many other frameworks) halve a year ago, and it took me some time to find a browser that would work with Echo (the demo apps were still terribly buggy). I think Browsers are not ready for client-side applications. Server side state in combination with very little AJAX here and there is much more reliable, easier to build and more useful. David H. Hansson (the RoR guy) wrote a nice article about how AJAX can be used in a sane way: http://www.loudthinking.com/arc/000428.html Neither Web 2.0 nor AJAX mean that you need a lot of Javascript. Web 2.0 isn't really about technologies, but more about business models: http://www.oreillynet.com/pub/a/oreilly/tim/news/2005/09/30/what-is-web-20.html I'm way off topic now, so I will end here. Only speaking for myself, but I think this is on topic. Timo --- Using Tomcat but need to do more? Need to support web services, security?

Johannes Fahrenkrug schrieb: Hi, It took me a while to track down why Opera makes my Wicket application look like crap. Here's why: when you use a css class like td.someclass and apply that class to a td tag within a table that is surrounded by wicket:border tags, Opera doesn't apply the CSS class to the td tag. If you define a general CSS class like .someclass it works (or when there are no wicket:border tags. Everything is fine when using Firefox, Safari or even IE. My question is: Can I somehow keep the wicket:border tags from showing up in the rendered markup? Yes. See here: http://www.wicket-wiki.org.uk/wiki/index.php/Remove_wicket_markup But your HTML is broken. There is no doctype declaration and the style tag is incomplete. If you declare the document as XHTML, the wicket tags *should* be ignored because they are in a different namespace. If they are not ignored, this is a bug in Opera, and should be reported.

I would like to know if Wicket can (or will shortly be able to) generate HTML elements (as well as doing all the other things it can do). By this I mean something like the old Element Construction Set (ECS) or perhaps even Swinglets. I've seen some discussion of this on the mailing list archive (although it is hard to follow threads via the archive), but it was mainly relating to Wicket possibly auto-generating prototype HTML if a HTML file was not available. I also understand that Wicket usually works with a HTML file and some may suggest using a Wicket panel for each possible element I wish to construct. That may be a possible but it doesn't seem elegant. However, I can't see why Wicket couldn't generate HTML when required, for very dynamic parts of a Web page. Wicket seems to have classes corresponding to most (if not all) HTML elements already. Of course, most dynamic Web pages won't need this, they just want to slot some dynamic content in an already setup HTML template, but I can also see where full dynamic control of the tags and content could be useful.

As I am coming from PHP I am used to a very quick function-call to find

You don't have to read the entire image. The dimensions are usually
embedded in some meta-data section, so it is not necessary to decode the
entire image just to get the dimensions.
This is how you get the dimensions from image files:
ImageInputStream i = ImageIO.createImageInputStream(new
FileInputStream(file));
try {
IteratorImageReader r = ImageIO.getImageReaders(i);
if (r.hasNext()) {
ImageReader reader = r.next();
reader.setInput(i, true);
width = reader.getWidth(0);
height = reader.getHeight(0);
formatName = reader.getFormatName().toLowerCase();
reader.dispose();

i.close();

Re: [Wicket-user] New Suggestion: Form components as labels
Ali, that's a nice idea. But I think it has some disadvantages: The TextInput component would have to change the entire tag. So it would have to be responsible not only for input tags, but for the static representation as a span or div as well. I am not a friend of putting that much functionality into basic Form components. Maybe it is an alternative to use the HTML standards to switch from editable to static textinputs? You can simply set the attribute disabled=disabled.

If you *do* have a complex but well-defined flow, why not encapsulate it? Igor said that he build a wizard with reusable panels and a state machine and I believe that it does the job well enough. But I want better than well enough :) But like I said, I wouldn't be against exploring continuations for Wicket in some contexts - like wizards -, if you have a good idea how this would be combined with component orientation I'd be interested to hear. I have made a proposal last year: http://sourceforge.net/mailarchive/message.php?msg_id=13995847 Johan pointed out some problems and suggested an interface IContinuation. But this would require some changes in the wicket core. Do you know any way to get around this core enhancement? I think it should be sufficient to have one Continuation per Panel, or maybe even one per Page.

I like this a lot better than spreading the logic over several components and handlers. So, I'm not pro continuations in Wicket at this point, except for the ajax optimization with Jetty, which will probably be implemented transparently. I am not asking you to write it :) I just want to discuss the idea, because I would like to know what benefit or problems/incompatibilities other people see.

Re: [Wicket-user] HTTP POST from Acrobat
Johan Compagner schrieb: you where talking about the PageParameters object so i thought you where talking about inbound stuff. Then every parameters will be in it. Ofcourse no multipart stuff and ofcourse outbound only what can be presented in a simple string can be added. Ok, so it doesn't work. That was a misunderstanding. We are talking about integrating wicket with other apps. For example Acrobat, which can send POST data (no URL parameters) from a form. That seems logical to me Yes, it is. But on the other hand there might be a need to integrate a legacy app with wicket that requires that a POST request is handled. Kurt is using a servlet to handle that request, and redirects to a bookmarkable wicket page. I thought about how Wicket could handle this directly, without a servlet in between, and PageParameters came into my mind.

Re: [Wicket-user] New Link component ?
Alex schrieb:
Hi,
we've been using wicket for about a month now, so far so good.
The only complain is about code lisibility, sometimes our constructors
are filled with a lot of code, particurally with all the :
add(new Link(myLink)
{
public void onClick(RequestCycle cycle)
{
// do something here...
}
);
If java had good support for closures, not just anonymous classes, the
syntax could be much more compact. A closure is a function object that
has access to the lexical environment of when it was created.
A closure could be declared like this:
String {Object t} manipulate;
String means that the Closure returns a String.
Object t is the only argument.
The definition of a Closure could look like this:
manipulate = {t | return t.toString + abc};
The part before | is the closure argument t. The part after | is
the body of the closure.
So instead of using anonymous classes and overriding methods like this:
new TextInput(myTextInput) {
@Override
String manipulate(String input) {
return input.toString() + abc;
}
}
The TextInput could accept a closure:
new TextInput(myTextInput, {t | return input.toString() + abc});
The constructor signature:
TextInput(String id, String {Object t} manipulate)
For more information, see the entry on closures in the wiki of the
excellent Martin Fowler:
http://www.martinfowler.com/bliki/Closure.html
[...] So we thought a custom component subclassing Link could force this
approach :
in constructor :
add(new ReflectionLink(myLink, myMethod))
and elsewhere :
public void myMethod() { // do something here ... }
Basically the ReflectionLink would contain some reflection stuff in
onClick(RequestCycle cycle) to invoke our method...
What do you think ?
What about something like this:
html:
input type=submit wicket:reflect=onMyAction /
java:
class X extends WebPage {
@Expose
public void onMyAction() {
System.out.println(myButton klicked);
}
}

You shouldn't. It might not give you problems right now, but you break
the contract with the interface.
You can cache the result so that you do only one query per request to
get both the result size and the result values. Use onDetach to clear
the cache after each request.
It should look like this (pseudo-code):
private List result;
void onDetach() {
result = null;
}
Iterator iterator(from, to) {
return getData().iterator();
}
int size() {
return result.size();
}
private Collection getData() {
if (result == null) {
result = dbquery(from, to);
}
return result;

You can do that directly from your link, without an intermediate page.

r.setContentType(application/octet-stream);
r.setHeader(Content-Disposition,

r.write(data);

[Wicket-user] Starting download after form submission [Wicket 1.1.1]
Hi, I have a filterable table (based on DataView - nice work, thanks Igor) and need a button to export selected entries as CVS. After form submission, I can simply get the selected entries from an extended IDataProvider implementation and generate the CSV data. But how do I get the data to the client? I searched the wiki, the mailing list and the API-docs, but couldn't find a solution. It would be great to be able to redirect to a resource just like it is possible with pages: setResponseResource(new MyResource(myData)); A less elegant solution would be sufficient. It would be fine to store the data on disk or in the session and redirect to a servlet to download. But I can't find any way to do this, either. Am I missing something?

Re: [Wicket-user] Starting download after form submission [Wicket 1.1.1]
Thanks Igor, I like this suggestion:
add(new Link(export-link) {
onclick() {
getRequestCycle().setRequestTarget(new ComponentRequestTarget(dt));
WebResponse wr=(WebResponse)getResponse();
wr.setHeader(blah);
}
}
But it requires wicket 1.2.
I tried to use a simple Page that outputs CSV instead of HTML, but I am
unable to set the proper headers in the response. They are simply ignored.
public class DownloadPage extends WebPage {
//...
public void onRequest() {
WebResponse r = getWebRequestCycle().getWebResponse();
r.setHeader(Content-Disposition, attachment; filename=\x.csv\);
r.setHeader(Content-Type, application/octet-stream);
}
I would have a look at the jasperreports project (though I doubt that it
solves my problem), but I can't connect to the servers.
I could even live with putting the information in the session and
redirecting to a servlet that outputs CSV. But wicket tries to modify
the headers after I set redirect headers, resulting in
WicketRuntimeExceptions.
Is there no solution? I really just want to return textual data with my
own content-type and content-disposition headers after a form submission.

Re: [Wicket-user] Good document explaining Models
It helped me to understand Wicket Models as an implementation of the Facade pattern.

So for every link/button you have you have a listview and/or panels in
wicket?
Yes.
Because you can't just not add a button/link if it is specified in the
markup.
Or add one that isn't specified in the markup.
The problem when you use for these kind of things listviews/repeaters is
that design is again must harder to do.
That's true. But on the other hand, there are only a very few pages that
have to be designed, because components are reused very often.
I like that a designer can design the complete page including all the menu's
and menuitems so that that page
has all the features.
Then in wicket we will add all menus/menuitems but the security framework
will let them render or not.
These links mostly don't have a model, it only points to another page class
and that page class is specified in the security settings
that a user can see that page or not and based on that the link is not
rendered.. So no model data nothing is specified for this
just pure wicket stuff.
This is in my case a very common usecase.
I understand. In early development stages, a new module in my app works
the same.

Re: [Wicket-user] Re: Security framework in Wicket
Johan Compagner schrieb: most of the time you want security over pages or links (rendered/shown or not) This can be very elegantly solved with an application model. For example, a navigation provider should only return navigation items the user has access to. As for other links/buttons that require access checks, they are most likely actions on model objects. So it's up to the model object to provide only the actions the user has access to. It should be easy to integrate a signin page and so on. Signin is part of the authentication (not authorization), and I concur that a web framework should provide hooks for it. that should be possible in wicket. And that is what the security interfaces (and an example implemention) is for just to provide hooks to do those things. Most people don't look at the model (data) for security things they have pages that they know are showing data. This argument nearly convices me :) Not all web sites one may want to build with wicket require complex model objects that handle authorization.

Eelco Hillenius schrieb:
I would like to put it a bit differently. Actually I think wicket is
more MVC than frameworks like struts are because we have the MVC at
the level of components instead of requests.
But to answer your question: yes it is a good idea to have such a
framework, even if you want to make authorization part of the model
layer. The mechanism we built in gives you a guaranteed mechanism to
plug in your authorization (in your case, like at Component.ENABLE),
and gives you the possibility to handle authorization exceptions at
the UI layer (because besides denying actions, you generally want to
communicate the denial in some way). So that works even in your case.
In my case, I don't even need authorization exceptions. It looks like this:
for (Action a : entity.getActions()) {
add(new ActionButton(a));
}
Furthermore I don't agree with the statement that it should be done in
the model.
It should be in an MVC application, especially if there is more than one
view. In my app, the model is accessed by an administration application
that uses Wicket, and a web service using standard servlets. Obviously I
don't want to write the access checks multiple times.
We are building a generic framework, so as much as we can,
we should enable users to decide on this themselves. And I think a lot
of times, authorization actually is more related to end-user
functionality that has a 1-1 relationship with the UI than it is with
the model layer. But... opinions differ and that's why we just try to
provide a generic framework.
I guess peoples opinions differ because the situations differ. In my
case, the security features of Wicket just add to Wickets complexity,
which is a bad thing. In other cases, it might be convenient to have
security support.
I would not trade simple design for convenience (I think it's better to
improve the simplicity of the design), but that is certainly just my
opinion.

Eelco Hillenius schrieb: Signin is part of the authentication (not authorization), and I concur that a web framework should provide hooks for it. Heh :) Don't agree. Authentication should be seen as part of authorization. Authorization is the end-means of seeing whether action x is permitted or not. Authentication is just a possible step to validate whether client a is who he states he is, and to get clear what security attributes are coupled to the client (like roles/ principals, etc). I know that authorization and authentication are intertwined, but while authorization only makes sense with some kind of authentication, authentication could be used without authorization: Take a simple operating system, for example. A user logs on (authenticating himself), and if the OS doesn't support authorization, he can access any file. If the OS supports authorization, it will check the owner, group and access flags, and decide whether the user has access. In a web app, the part of the application that handles requests is responsible to authenticate a user (even if it is just for http sessions). That's why I think that it should support authentication to some degree, but does not have to support authorization at all. Not all web sites one may want to build with wicket require complex model objects that handle authorization. But do they really require security support from wicket? Then don't use it. It's just a hook. The hook is built on a more generic hook too. We found the need to have a mechanism for authentication that is supported out of the box, and it has been requested by many users. I agree a framework should provide for anything and it's mother, but in this case I think Wicket needed the ability to at least cooperate on this with other layers of your application.

[Wicket-user] Wicket Application behind a proxy
Hi. I have to use a proxy (apache with mod_proxy) in front of my wicket application. This means that all redirects (and requests) must point to the proxy server, not the wicket application. So my question is: Where can I modify the construction of redirect URLs in wicket? Timo --- This SF.net email is sponsored by: Splunk Inc. Do you grep through log files for problems? Stop!

Re: [Wicket-user] Wicket Application behind a proxy
Hi Flemming. Thanks for asking, I guess my question was too unspecific. Flemming schrieb: I also use mod_proxy with wicket, but I have not encountered any need to modify the urls. What is causing you to do it? It is a requirement of some important legacy apps and can't be circumvented. All request must go through the proxy. I have a proxy server: http://proxy.com/ All requests to the proxy must be forwarded to the app server: http://app.com/.../wicketapp/ The request forwarding works flawlessly, but the redirect locations created by wicket point to the app server. This is what I expect, but I need these redirects to point to the proxy server. For my JSP-based apps I simply had a utility method to construct all redirect urls. But in wicket, explicit redirects are very rare. The are mostly created and handled internally. I just need a hook where I can control all redirects.

So if wicket generated a URL pointing to localhost:8080/my-wicket-app/foo.jpg the reverse proxy would convert that to www.myapp.com/foo.jpg That may be what you're missing.

Yes, the load on the webserver would increase.
If we build something like this in wicket. Where would youre code be in?
Now youre pieces of youre code is in the event/interface methods like
onclick or onsubmit.
Would you then have an onClick/onSubmit on a Page? and every thing that
comes in from that page
is called to there or better said it is continued there?
How would you say to wicket i want to start this part in a continue, a
special interface that a page
implements that is checked on in the response phase?
My opinion on implementation in Wicket lacks a lot of insight - I don't
have time to really dig into wicket interna until next year.
I guess there are similarities to the handling of AJAX requests at a low
level. Maybe there is a chance to generalize this and add all kinds of
request handlers.
Where to add a hook for the user? Continuations would be used for flow
control, so they would be part of the Control layer of the MVC paradigm.
If Wicket Components are the View, they should not need to know about
Continuations.
I am thinking of an Object that takes over control from a certain
starting point. For example, you would have a button labeled start,
whose onClick handler creates an instance of the Control Object and
passes the context on (if necessary).
The Control Object should have a method to send a Page to the client
(i.e. set the Response Page) and wait for the next Request for a Page.
I do think this thing is not for all. Only small portions, one page. else i
think you quicly get big
monolitic code again.
Yes, continuations certainly don't make sense for every kind of application.
I think that continuations would be very convenient for some
well-defined workflows, but it does not make sense to use them
everywhere for the reasons you mention.
If i compare it to swing then i just see this continuations as the Modal
Dialog...
That is the continuation in swing. You block youre current code and ask the
user for something.
Then it gets back (the modal dialog is closed) and you continue.
Yes, this is the idea. Just like the JavaScript alert(), confirm() and
prompt() functions.
lets think about some examples how we would do this in wicket and what would
be a elegant way.
Let's say we have the Control Object mentioned above. The most important
public method would be:
WebPage sendAndWait(WebPage p);
(This method hides all the dirty work from the user, add a Request
handler, etc.)
I think it would be convenient to provide methods for common tasks:
void alert(String message);
boolean confirm(String question);
String prompt(String question);
These methods send a default AlertPage, ConfirmPage or PromptPage,
evaluate the result after sendAndWait() returns and return a proper value.
An extension of the Control Object could provide methods for simple
creation of Dialogues. Example:
DialogueModel ask(DialogueModel d);
Usage:
DialogueModel userInfo = new DialogueModel();
userInfo.addStringInput(name, What is your name?);
userInfo.addStringInput(color, What is your favorite color?);
while (userInfo.hasEmptyInputs()) {
ask(userInfo);
}
You don't have to care about the view at all at this level of
abstraction. You just work with the model.
Any comments are welcome,
Timo

Just plain text with dots. This makes it very easy and fast to parse.
but if people really want this:

I can think of two reasons why an access operator [] could be useful:
- It might make the expression more readable, because you know that you
are operating on an array, List or Map by looking at the expression.
- The content of the access operator could be an expression itself. Example:
person.children[person.selectedChildIndex].name
But I think this is already too much functionality. I would prefer the
most simple approach with only the most basic support for arrays, Lists
and Maps using only dot-syntax.
There is one issue that's very important to me. I have run into this
using the Expression Language of JSP 2.0:
If you have a class that implements Map, you can not access a bean
property on the instance.
Let's say we have the following class:
class Bar extends HashMap {
public String getFoo() ...
}
Now create an instance and populate it:
Bar b = new Bar();
b.put(yadda, value);
The JSP EL Evaluator would return null for the following expression:
b.foo
I think the Evaluator should look for a value in the map using
containsKey() and look for a bean property if nothing was found. On a
list, you could check if the key is numeric.
This would not be a performance hit, and you are still able to use the
instance like any other object.

My point is: Brackets can be useful for the two reasons I mentioned. If you do not intend to support these features, there is no reason to use brackets in the syntax. I though about this (List and Maps being beans) For a list this is not that hard because if the next expresion can be converted to an int then it is just an int for the index. (get1() is then not supported) And if it can't be converted then we could check if a method is there. For maps this is different. Currently i see List/Maps are not beans. If i always use them as a List or Map. First check if something is there (in the map) looks strange to me. It gives better performance. Because what happens if you do this: mymap.value = x and there is a setValue() but not a map entry? Should i use setValue or do a map update. (or both?) That's true, I didn't think of this situation. So it is necessary to check for getters/setters before doing map stuff. This would be the following accessor precedence: 1 getter/setter 2 List 3 Map I don't know if the performance hit is too high to allow getter/setter access on Maps and Lists, but I would certainly like this feature because it is an requirement of a framework I am using.

It would still be nice to have an OgnlPropertyModel, even if it doesn't
have an accompanying compound model. Sometimes a complicated expression
is just what you need, and I'm not crazy about putting those in a

Around 40% speed increase for a submitting the forminput example page
20 times
and only 1/5 of the memory garbage is generated (50MB against 10MB)
The question is what do you guys use of ognl? Can i completely drop it
or must i make it an option so
that you can switch in youre application for all using ognl or the
homebrew wicket impl.
Or make seperate classes (like AbstractPropertyModel) but this is not
really doable because then all the
sub classes must also be copied...(Like CompoundXX)
What i do support now is this:
person.name http://person.name (plain properties)
person.addresses.0.street (addresses is a list and i take the first
element)
person.addresses.homeaddress.street (addresses is map and i take the
address with the key 'homeaddress' out of it)
so maps and list are seen and the next part of the expression is then
the key or the index you can also put values in a map
or append/set to a list:
person.addresses.homeaddress = new Address()
person.addresses.10 = new Address()
if the list size is smaller then 10 then it will appends null to make
it that size.
addresses can also be an Array but then it won't be able to grow.
Ofcourse the person.address.street will just be null if address is
null, no exception will be thrown
if you try to set something on a null object a exception is still
thrown, Maybe we could make some null handlers for that somehow that
are easy useable.
So can people live with this? Does anybody uses something different of
ognl?

Hi list, I have created a navigation menu component and a menu model.

The menu must remember which item is selected (the state is representable by a simple String). Now I have the following problem: Where do I keep the state of the menu?

Eelco Hillenius wrote: /The/ big difference between a component/ event based framework like Wicket and a (web) continuations framework is that with Wicket your focus should be what's on your pages and how it reacts to user input, using different pages to address different areas of functionality, while with a continuations framework you focus on the flow of the application (think in flows and have things like 'processAndWait' as transition marks). There is no 'better' approach imo. For the kind of applications I am usually involved in making, Wicket is a better fit, and in my experience analysts are usually more focussed on direct interaction/ domain functionality than on flow. Might be different for you though. This sounds like an apology ;-) But there is no reason to apologize. I consider Wicket the best choice in java web frameworks for most applications. It lacks tutorials and and third party libraries to compete with Struts and other more wide spread frameworks, but it is obviously technically superior. Especially when compared to Struts :-) Back on topic: I understand your argument that [wicket] does the same thing as the original definition [of continuations]. You said that even though implementation may differ, the net effect is the same. Of course that is true. From your linked page on common-lisp.net: Continuations in web apps do not allow you to do anything which can't be done without them, though i'd argue that there are certain user interactions which are too complex to manage (for a developer's point of view) without them. There is no native support for continuations in Java, so it is neccessary to emulate their behaviour to allow for flow oriented programming. Sure, Wicket is not incompatible with such an emulation of continuations, but there is no determined support for flow oriented programming as well. Is support for flow oriented programming necesary? I think it is highly desirable. With abstractions of data objects and editors (in the spirit of the Code generator / Prototype generator thread), you can concentrate on the most important part of most applications: the flow. If you don't have to spread your business logic and work flow over several classes and layers, you will simply increase the code quality. I have had a quick look at RIFE/Continuations, and it looks usable. There is a presentation that gives an immediate impression: https://rife.dev.java.net/files/documents/204/3120/rife_fosdem_2004.pdf (page 5 to 8 are the interesting ones)*.

The original idea of continuations is to never return a value, but pass a context object (continuation) to the next function call. That idea translated to webapplications seems to be to have a 'wait-for-input' concept, so that you can model a flow like a couple of linear steps that conceptually 'pause'/ wait for input before it moves to the next step. As Wicket has a current state and does not work with return values for flow, I think we could defend that we do the same thing as the original definition, though with a slightly different flavor.

Fisheye is more comfortable to browse than viewvcs, and the sourceforge server is also a bit slow with responses at peak times. I guess a link on the wicket site would be nice.

I agree. You can (to a certain degree) dynamically create objects at runtime that implement known interfaces, or use Javas API for dynamic data objects, the collection framework.

David Liebeherr wrote: With generated code (from customizable templates) i am able to generate a functional application very quick and i still have the possibility to customize the app later. If you make changes to the generated source, you loose the ability to change the parameters (templates) of the generator after you made changes. This would be a major design flaw in my opinion. I think one common misthake in this discussion at this point is the understanding what a code generator does or is good for. What i am thinking of is more a Prototype generator than a code generator which generates full apps for me. I'll try to explain: [...] Really, have a look at trails, I think you can get some ideas there.

David Liebeherr wrote: Hi! Today i read a pretty much interesting article about Ruby on Rails (RoR). First things first. I don't like ruby. Then you may want to have a closer look at RoR. :) There is a presentation video with David Heinemeier Hansson (the author of RoR) that gives a good overview of RoR, and also shows how Ruby contributes to RoR: http://www.rubyonrails.org/media/video/rubyonrails.mov But: The Aproach of Ruby on Rails is very impressing and provides a effective way to write standard Web-Apps. So i like the way how wicket works much. And now i am thinking about to adopt some ideas of Ruby on Rails to wicket. The most interesting and time saving aspect of RoR is that it has mayn scripts to automaticly generate Formulars and Lists so that you can deal with Datas which mostly comes from a Database. RoR goes way beyond that. Ruby is a very reflective language, much more than Java. Of course you can try to reproduce RoR in Java, but it will fail in some parts because of language restrictions, and it will certainly lack the elegance of RoR. More on that below. I think a similary tool could be made for Wicket. The features i think of are somehting likt this: -Gernation of Formulars and Lists from the Strucure of a certain Database-Table (Or JavaBean Class). There already is a BeanEditor in the wicket examples. Which includes the generation of: Wicket-Class, Wicket-HTML-File and that all already ready with all necessary connections and handling to the database or the JavaBean object. I think code generation is a bad idea. It works in certain cases where code generation and compilation are completely hidden from the user (see JSP). My question now to you guys is: 1. Is already someone writing such a Generator? There is a project that tries to reproduce RoR in Java. It's called Trails. It uses some code generation (using eclipse to generate getters and setters). Well, it utterly failed to reproduce the simplicity and ease of use of RoR. 2. What do you guys think about this idea?

What I do for an app I'm working on now, is to use ajax components for
the fields that allways need to be current.
I am absolutely new to wicket, but can't you just pass on the page
instance? This should keep the state, if I am not entirely misunderstanding.
Assuming we have page A, the master form page, and page B, which will be
used for some inputs on page A.
class A extends WebPage implements BDataReceiver {
... button handler {
getRequestCycle().setResponsePage(new B(A.this));
}
public void setBData(Object o) {
...
}
}
class B extends WebPage {
private BDataReceiver from
public B(BDataReceiver from) {
this.from = from;
}
... button handler {
from.setBData(...);
getRequestCycle().setResponsePage(from);
}

Re: [Wicket-user] Good way to back up form state?
Eelco Hillenius wrote: Actually, when you look closer to the whole continuation thing, continuations are not so incompattible with how Wicket works now. I guess the problem is that continuations are not really compatible with java. An elegant implementation of continuations in java seems to be impossible. The original idea of continuations is to never return a value, but pass a context object (continuation) to the next function call. That idea translated to webapplications seems to be to have a 'wait-for-input' concept, so that you can model a flow like a couple of linear steps that conceptually 'pause'/ wait for input before it moves to the next step. As Wicket has a current state and does not work with return values for flow, I think we could defend that we do the same thing as the original definition, though with a slightly different flavor. At least it has the same net effect. And... if you want to do the web variant of continuations... that's easy... just create a mini framework that handles the flow and - I think - you're done. That would just be a state machine. Or... maybe I don't get the idea of continuations just yet. Please correct me if that is the case :) Have a look at this article: http://www-128.ibm.com/developerworks/library/j-contin.html Jetty 6 is going to have continuation support. Are there any plans of supporting jetty continuations? http://www.mortbay.com/MB/log/gregw/?permalink=Jetty6Continuations.html Timo --- This SF.Net email is sponsored by: Power Architecture Resource Center: Free content, downloads, discussions, and more. http://solutions.newsforge.com/ibmarch.tmpl ___ Wicket-user mailing list Wicket-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wicket-user
