Re: [Wicket-user] Overriding onRender() for BookmarkablePageLink
Playing devil's advocate here: so what's the point/benefit of
preventing a call to setEnabled() if one can override isEnabled and
modify the hierarchy beyind Wicket's back anyway?
I personally prefer explicit calls to setEnabled() from onRender() than
subclassing because it allows me to know upfront exactly where its value
is being changed (plus you don't have to recalculate the value if it
hasn't been changed).

Re: [Wicket-user] Overriding onRender() for BookmarkablePageLink
Playing devil's advocate here: so what's the point/benefit of preventing a call to setEnabled() if one can override isEnabled and modify the hierarchy beyind Wicket's back anyway? That setEnabled method records a change and is thus useful for a visibility flag that has to roll back with back button clicks. For instance, when you have a user action (e.g. a button) for enabling/ disabling the visibility of the component. But when you calculate whether a component should be displayed or not, it might actually be a better idea to override getEnabled, as that will guarantee the behavior based on the current application state and will thus not be stale. From an API point of view, this one is less tight, and we discussed a couple of times whether we should make getEnabled final or not. We concluded that having that method overridable is just too useful, so we didn't make it final.

Re: [Wicket-user] Overriding onRender() for BookmarkablePageLink
Absolutely, I can see why it would be useful to override getEnabled() when your state depends on many factors (some of which you cannot hook). I can also see the case where setEnabled() is simply easier to use for more static or hookable factors. Anyway, good to know.

Re: [Wicket-user] What about Wicket Javascript and Browser errors?
igor,
I work with Netbeans 5.0 bundled with tomcat 5.5.9
so i have uploaded the tinyest netbeans project sample as i copied it code for code in the ajax example
My headache is that most of my applications involving _javascript_ likedojo-contribsworks fine under wicket 1.1.1.
but when i switch development to wicket 1.2 (excluding all 1.1.1 related contribs) i still get the browser problem.
When i deploy the example WAR, the Ajax runs fine but when i deploy my own WAR from Netbeans of my application, the browser gives _javascript_ errors and Even when i use PackageResourceReference

[Wicket-user] Parsing URL upon session creation
I have a requirement where I need to parse the URL to extract a username on session creation. For example, http://username.foo.com/..., I need to pull out the username and set a style in the session.

return new FooSession(); } }; }So in the newSession method how can I get the URL or request object?Thanks,Andrew

Re: [Wicket-user] Javascript error when using AjaxCheckBox - Wicket-1.2-beta1
i think the problem is that you didnt call checkbox.setOutputMarkupId(true) so its markup id never made it into the markup.i made the ajax behavior smarter, it will now call that for you whenever it is attached.
so either do the call yourself, or update to trunk.-IgorOn 3/16/06,

Re: [Wicket-user] Examples of model decorators
not really sure what you mean...but here is a simple decorator that does uppercase on the model object, assuming of course its a string.class UpperCaseModel implements IModel { private IModel delegate;
public UpperCaseModel(IModel delegate) { this.delegate=delegate; } Object getObject(Component c) { return ((String)delegate.getObject(c)).toUpperCase(); } void setObject(Component c, Object o) {

Re: [Wicket-user] objects in session
Hey Vincent,
What I would do is override getSessionFactory in
your application class, something like this:
@Overrideprotected ISessionFactory
getSessionFactory() {return new ISessionFactory()
{
public Session newSession()
{return new
MySessionObject(YourApplicationClass.this);}};}
Now MySessionObject is a subclass of WebSession
(You'll want to look at this class). In your pages you would do something
like:
((MySessionObject)getSession()).getUsername();
Make sense?

[Wicket-user] Difference between Panel and Border
Hi, A beginners question, what is the difference between a Panel and a border component? I tried to use them both and I couldn't tell the difference between the two. I found this description on wicket-wiki: |The Panel component is a component that groups together a collection of other components and have an |associated markup. It is the basic building block for reusable site elements. |The Border component provides a way of wrapping a set of markup around a markup container. Typically the most |common use to to provide a common site template (e.g. header, footer, menu etc.) that gets wrapped around |individual content pages. The result being that top level site layout only needs to be maintained in one |markup file. However, the Border component is much more powerful than this simple use case as it can be used |to achieve exactly the same functionality for individual elements on a page. Ok, so they both are containers for other components and they can have markup. They say the difference is that the Border component is more powerful. so why does a Panel even exist then?

Re: [Wicket-user] objects in session
Just as an observation, this seems a bit cumbersome to simply add/access/remove objects from the HttpSession (but that's just my opinion.)It make sense, it just seems like a lot of work to tap into session values.
I suppose if I had a single getter/setter that used an Object parameter I could make something that behaved more like the HttpSession when used in JSP/Servlets...but then I've got to override getSessionFactory() in every Application class I want to use it in.

Re: [Wicket-user] objects in session
we do not provide that get/setObject() method because we want to encourage type safety.furthermore the session is also used to store application logic, like logic related to authentication/authorization or anything else youd like. it is not a simple MapString,Object like http session, it can be much much more.

Re: [Wicket-user] objects in session
One thing to keep in mind is that you could put a
method in your page subclass like:
public class MyWebPageSubclass extends Webpage
{
public User getUser() {
return
((MySessionObject)getSession()).getUser();
}}
this would allow you to abstract some of the
chained invocations if that's what you're referring to. Aside from that
javax.servlet.http.HttpSession is not typesafe. Wicket is doing you a
favor by insulating this from you, be happy not frustrated! :)

Re: [Wicket-user] objects in session
I see, well I'm not complaining but my point is; it's just not simple to use and in most other aspects...wicket is worlds easier than JSP + Servlets. Perhaps there needs to exist a sub-implementation of WebSession that is global and easy to access use...just for those of us who don't need to use it for much.
Anyhow I seem to be having a problem getting it working...here's what I've got so far.Here's my session class:public class UserSession extends WebSession{ private User user; public UserSession(Application application)
{ super(application); } public User getUser() { return this.user; } public void setUser(User user) { this.user = user; }
public boolean authenticate() { if (this.getUser() == null) return false; else return true; }}I modified my EditProductApp class to include the overridden method:
public ISessionFactory getSessionFactory() { return new ISessionFactory() { public Session newSession() {return new UserSession(EditProductApp.this
); } }; }In the page, I check to see if the user exists: UserSession us = new UserSession(EditProductApp.get());if (!us.authenticate()) setResponsePage(new Login());
...if not, I send them back to the login page...the problem is; they *always* get redirected...so to continue w/ the login page:the login app class overrides the getSessionFactory() method: public ISessionFactory getSessionFactory()
{ return new ISessionFactory() { public Session newSession() {return new UserSession(LoginApp.this); } }; }
the login page submit action looks like this: //event handler public void onSubmit() { //authenticate user User formUser = (User)getModelObject();
User dbUser = UserProxy.getAuthUser(formUser.getUsername(), formUser.getPassword()); UserSession us = new UserSession(LoginApp.get()); us.setUser(dbUser);
if (dbUser == null) {setResponsePage(new Login()); //login failed } else if (dbUser.isActive()) {if (dbUser.getUserGroup
().getAccessLevel() == 1) setResponsePage(new Home());else setResponsePage(new ProductCatalog()); } else {
setResponsePage(new InactiveAccount()); } }So, I login (that part works fine) and then go to the EditProduct page and get redirected to the Login page...the value was apparently *not* stored in session.

Re: [Wicket-user] Difference between Panel and Border
The description is a bit whacky. A panel is a container that replaces any contents.

Re: [Wicket-user] objects in session
UserSession us = new UserSession(EditProductApp.get());this is wrong, you dont create the session yourself, you let wicket create it for you (thats why you return a factory)so in your page:UserSession session=(UserSession)getSession();

Re: [Wicket-user] objects in session
It is a major goal of Wicket to simplify things. But not the only/
utmost. There are a couple of good reasons for the way we implemented
session:
1) Discourage direct usage of HttpSession.
- If you play by the rules and use the Wicket Session, you may
later decide to store the session e.g. in a database instead of the
actual HttpSession object.
- you have a central session object that you are in control of and
that you can enhance with things like auditing etc.
2) Promote type safety. Just look at your session object to see what
is (potentially) in there. Much better than a hashmap.
3) Enforce an explicit contract. As you can't just put anything in it
(unless you provide your own hashmap based implementation of course),
you have to think about it better, and make concesious decissions
about what you want to support as session scoped data. In other words,
we let you define an explicit contract for your application/ API
users, which is one of the key concepts of object orientation after
all.
Now, like I said, you can break out of this by implementing your own
hashmap based implementation, maybe combined with some utility methods
to make accessing it easier:
public static void put(Object key, Object value) {
((MyUglyHashmapSession)Session.get()).put(key, value);
}
public static Object get(Object key) {
return ((MyUglyHashmapSession)Session.get()).get(key);
}
But I am definitively not recommending it.
Hope this helps,
Eelco

Re: [Wicket-user] Parsing URL upon session creation
It's actually pretty awfull. I don't really see the point of having to
create the session upfront AND delegating the creation of the request
cycle to the session which in turn delegates it to the factory which
is set in the application. The problems I have with the current
handling:
1) It seems to stem from an optimization (RequestCycle sets the
Session as a final field so it doesn't have to use the thread local)
only. I don't think we need the optimization and besides the same
could have been accomplished by just lazy loading it.
2) I find it illogical that the session is there before the
request(cycle). The other way around would be more initiutive and
useful.
3) All that that one-liner delegation method does is tighten coupling.
The factory method in session is meant for internal use only. We
should loose it.
What I propose:
1) Create RequestCycle before the session.
2) Use the Application's factory directly instead of passing via
Session, and remove the method in Session.
3) The session is lazily created in getSession of Application. I
propose to 'touch' that method in RequestCycle's constructor to ensure
it is available for any user that wants to access it in the
constructor of any custom RequestCycle.
4) Make the change ASAP/ before beta 2.

Typically the most |common use to to provide a common site template (e.g. header, footer, menu etc.) that gets wrapped around |individual content pages. The result being that top level site layout only needs to be maintained in one |markup file. However, the Border component is much more powerful than this simple use case as it can be used |to achieve exactly the same functionality for individual elements on a page. Ok, so they both are containers for other components and they can have markup. They say the difference is that the Border component is more powerful. so why does a Panel even exist then? I am confused. Thanks, Tom van Zummeren --- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.

[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] Re: Re: Get version of Wicket from program
What about using Package interface? Class cls = Class.forName(wicket.Application); Package pkg = cls.getPackage(); String name = pkg.getName(); String specTitle = pkg.getSpecificationTitle(); String specVendor = pkg.getSpecificationVendor(); String specVersion = pkg.getSpecificationVersion(); String implTitle = pkg.getImplementationTitle(); String implVendor = pkg.getImplementationVendor(); String implVersion = pkg.getImplementationVersion(); implVersion holds the wicket version, e.g., 1.2-SNAPSHOT Finally this works for me: URL url = WicketServlet.class.getProtectionDomain().getCodeSource().getLocation(); url = new URL(jar, , url.toString() + !/META-INF/MANIFEST.MF); Manifest manifest = new Manifest(url.openStream()); Jan Martijn Dashorst [EMAIL PROTECTED]wrote in message news:[EMAIL PROTECTED] wecould check the manifest ourselves in wicket servlet orapplication.

Re: [Wicket-user] Parsing URL upon session creation
That would be awesome Eelco if that happens. It does make more sense to have the request available before the session is created. Please let me know if and when you make this change so I can change my code and/or test this for you.
On 3/16/06, Eelco Hillenius [EMAIL PROTECTED] wrote:
It's actually pretty awfull. I don't really see the point of having tocreate the session upfront AND delegating the creation of the requestcycle to the session which in turn delegates it to the factory whichis set in the application. The problems I have with the current
handling:1) It seems to stem from an optimization (RequestCycle sets theSession as a final field so it doesn't have to use the thread local)only. I don't think we need the optimization and besides the same
could have been accomplished by just lazy loading it.2) I find it illogical that the session is there before therequest(cycle). The other way around would be more initiutive anduseful.3) All that that one-liner delegation method does is tighten coupling.
The factory method in session is meant for internal use only. Weshould loose it.What I propose:1) Create RequestCycle before the session.2) Use the Application's factory directly instead of passing via
Session, and remove the method in Session.3) The session is lazily created in getSession of Application. Ipropose to 'touch' that method in RequestCycle's constructor to ensureit is available for any user that wants to access it in the
constructor of any custom RequestCycle.4) Make the change ASAP/ before beta 2.EelcoOn 3/16/06, Igor Vaynberg [EMAIL PROTECTED] wrote:

So in the newSession method how can I get the URL or request object? Thanks,

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.
