Re: [Wicket-user] Palette problem with latest snapshot

But could it be that there has been a change in the component hierarchy of Palette, and your own markup is now incompatible with it? We always use a snapshot of the current day and have extensive JUnit tests (covering about 90% of the lines). This makes it a lot easier to notice and fix this kind of problems, as we can easily see from commits / dev / user mailing lists what is going on, and just diff the whole wicket source code when needed.

[Wicket-user] Form inside a modalWindow inside a Form :-/
Hi, i'm having an strange behavior in my application. i have a form with a listview inside and the items in this listview can be reordered using buttons (that's why the list is inside a form). In the form i have a link that opens a modalWindow to add a new element to my list (the link and the modal are defined as elements inside the form). This modalWindow contains a new form to complete the necesary information and a button to close the modal and add it to the original (reorderable) listview. The thing is that the 'second' form created inside the modal does not write the html correctly and thus the javascript fails with form has no properties. Using firebug i could find that the modal doesn't have the form tag inside, after the div defining the window it just have the all the inputs and selects, so when javascript is looking for it to make the submition, it fails. I added setOutputMarkupId(true) to all my involved components to check if i was missing something but still has the same issue. I think there is a bug in somewhere... what do you think? there's some workaround for this? thanks a lot. -- D. - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

Re: [Wicket-user] Location of css, images, js files
Tauren Mills wrote: My goal is to allow a client with minimal web design skills to manage the html, css, image, and properties files with minimal risk of damaging the application. I'd like the java class files to be located in a separate location. And I'd like the folder structure of the webroot to be clean and make sense to the designer. Can you give us more information on how things are not working as expected? Specifically, how are you linking to your CSS/JS files? I presume you're using resource references, and instead are including link elements in the HTML? Is Wicket rewriting these? See PrependContextPathHandler. This should make your JS/CSS links absolute, against your context root. If your HTML files are in there too, then this should Just Work. Note that I don't think putting your HTML files into your web context root is a great idea (at least, not for deployment). You could instead create a parallel source folder (if you're using Maven 2, src/main/resources is automatic, and is ideal for this), and get your web designer to put the CSS link elements inside a wicket:remove tag. You'd then just go add(HeaderContributor.forCss(getClass(), foo.css)); in your actual code. This has the benefit that if you wish to refactor bits of your app out into libraries, all the CSS/HTML/etc. comes along with it, and it all gets automatically packaged up my maven or whatever. Other than that, I'm not sure if there's a more elegant way of doing that in Wicket 1.2.x (1.3 makes this a little easier). Anyone else?

Re: [Wicket-user] wicket-contrib-gmap2
I really think you guys should get together and do this, right now while the project still has lots of momentum and the code is fresh. Having two components, one of which seems to have a superset of the functionality of the other, seems a little unnecessary. I've checked gmap2 out, BTW - very nice. ;-) Al Iulian Costan wrote: yap, well done, also maybe we can put together the effort and improve things. /iulian On 6/14/07, Nino Saturnino Martinez Vazquez Wael [EMAIL PROTECTED] wrote: Hi Martin Well, both Iulian and me has done a lot of work on this during the last couple of weeks. It's always nice to see to sides of the coin, maybe we should pick the best stuff from our components and join up? Currently Iulian are working on upgrading the gmap contrib to wicket 1.3, we decided not to make a release on wicket 1.2.6 since some of the ajax stuff we are using arent working on the IE browser series(I have another thread concering this). Upon releasing v 1 we will update confluence so that the features we are using will be shown installation instructions etc, heres a short list of features: All updates done via ajax, clicklisteners of all sorts(dragend, zoomend). Possibility to integrate loading screens. 2 step initialized and refresh, meaning no visible postbacks, we are using panTo. Control the map serverside eg if user clicks the las vegas button the map will pan to that area. Add overlays at will. Create custom overlays with tooltips. Since we are using ajax all normal wicket ajax behavior are also supported from the ajax target. Not sure if I forgot anything... regards Nino Martin Funk wrote: Hi, may I draw your attention to a little project I was allowed to add to the wicket-stuff svn repository yesterday. Being highly inspired by Julians and Nicos wicket-contrib-gmap I got exited enough to try to create a project that does the same and a little bit more with a little different approach. Kinda bold, since I haven't looked into JavaScript before. Julian and Nico I hope you don't mind that I tried to invent the wheel a second time, but if your project wouldn't have been around I probably never would have tried. So thank you for that. Features: There can be more than one GMap on a page, I think there can be many, at least I succeeded with two. Components may become controls of the GMap. Any Component capable of firing events can become a controller. The controls are executed whenever the named event is fired by the Component. Currently ZooOut, ZoomIn, PanDirection, AddOverlay and OpenInfoWindow are implemented. Listeners may be added to the GMap. These are called whenever the GMap fires the corresponding Events. So far a ClickListener and a MoveEndListener are implemented. This allows to dynamically update any Component and the GMap itself. The events and the controls always do a round trip from the browser to the server and back, this way any call can be intercepted and controlled on the server side. The network traffic is kept down, since all needed JavaScript functions are defined in a js-file. So only arguments have to be transfered. Status: Is best described by, consolidating. As I said, being a JavaScript newbie and a Java mediocre, it was sort of bold to start this. The features in mind I basically cut right through any API ahead of me without taking care of any design principles. So if you ever find the time to look into the code, give feedback! And I fear this project is in need for a lot of feedback. Last but not least: Installation. There is no release currently planed. The code compiles against the current HEAD of wicket. So get get wicket from svn as described in http://incubator.apache.org/wicket/building-from-svn.html first. This project relies on the well maintained structure of wickets pom.xml files. It needs to be checked out into wicket jdk-1.5 folder: cd wickets-jdk-1.5-folder svn co https://wicket-stuff.svn.sourceforge.net/svnroot/wicket-stuff/trunk/wicket-contrib-gmap2 svn co https://wicket-stuff.svn.sourceforge.net/svnroot/wicket-stuff/trunk/wicket-contrib-gmap2-examples This should do the install and get a jetty started for the examples: mvn -f wicket-contrib-gmap2/pom.xml install mvn -f wicket-contrib-gmap2-examples/pom.xml jetty:run Now browse to: http://localhost:8080/wicket-contrib-gmap2-examples/gmap/ and click around.

Re: [Wicket-user] Prototype scoped Spring beans
I finally had the time to try this out. The re-injection after de-serialization apparently works now. However, the problems didn't stop there, as I was accessing DAOs and an EntityManager from within this bean. I read more stuff on that ( the book Java Persistence with Hibernate covers this pattern quite well), and came to the conclusion that all the trouble involved is not worth it in this particular case. Just to put some more detail to this: I developed this particular bean as a stateful EJB on Jboss. But as development on Jboss is often very slow when you have to restart your server (at least compared to Jetty), I switched to Spring. This solved some (not all!) of the problems I had there, but raised the ones I discussed in this thread. At least with the current state, I would discourage anyone implementing long conversations within spring beans. Some of the magic happening in EJB (like propagating the right EntityManager to your stateful DAOs) is just not there yet; or at least I don't see it :) The following thread was not very encouraging either: http://forum.springframework.org/showthread.php?t=39523highlight=long+conversation Still, thanks a lot again, Igor. In some other context, this might very well become useful. Rüdiger 2007/6/13, Rüdiger Schulz [EMAIL PROTECTED]: Igor, that makes perfect sense, thank you very much. I still have to try it, but if it works with @Configurable, this will be great! It is definitely better than implementing readResolve(), and manually injecting the dependencies via reflection, as someone suggested on the myfaces list. I'll post my experience after trying it. Rüdiger 2007/6/12, Igor Vaynberg [EMAIL PROTECTED]: if you think about it, your problem comes from the fact that you do not want to serialize this stateful bean because it has references to other beans which are not serializable and yet you want to put it into httpsession. the requirement of anything you put into httpsession is that it _is_ serializable for replication to other server nodes, etc. - unless you use some nonstandard replication technique. shale will run into the same limitation. its dialog scope is pretty much the same as making something a field of a page. that field is there while the page is, and is then cleaned up when the page is not needed. however it runs into the same limitation because it most likely uses httpsession for storing that dialog-scoped data and thus you are back to serialization problem. now a solution i see is thus. make this bean @Configurable and serializable. keep all dependencies in transient vars. that way when the bean is serialized its dependencies are not, and when it is deserialized i think @Configurable wires in an intercept that will reinject the bean. that way you get the best of both worlds. makes sense? -igor On 6/12/07, Rüdiger Schulz [EMAIL PROTECTED] wrote: 1) Convert the bean to a stateless service, and keep the state in another bean. 2) Make the bean references transient, and re-fetch them manually (i.e. without DI from spring) after de-serialization. There is nothing wrong with 1), I use it in other parts of my app. It sure would be nice to have stateful beans with DI-ed application logic, but 2) seems very clumsy. However, later in the above thread, someone mentions the dialog feature of Shale: http://mail-archives.apache.org/mod_mbox/myfaces-users/200609.mbox/[EMAIL PROTECTED] Maybe something like that could be applied to wicket as well? - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

Re: [Wicket-user] HomePage url changes when user returns from a second wicket page
Page A has this code in its constructor:
Link b = new Link(b){
public void onClick(){
setResponsePage(B.class);
}
};
add(b);
Page B has a no-args constructor. It has a link to page A. It also has a
form (with a bit of Ajax) which takes some user input. The no args
constructor writes a debug message In constructor of class B.
The user starts on page A, clicks the link to B, enters some data into the
form on B, clicks on the link to A and then clicks on the link on A to go
back to B; all the user's data has disappeared.
In fact, B's constructor has been called twice.
Is it not the case that the setResponsePage(B.class); (as opposed to
setResponsePage(new B());) should use the _original_ instance of B, which
was stored in the user's session (as per the perfectly reasonable post
below)?
How can I achieve the desired effect (ie not losing the user's input on
returning to B) ?
Is the only way to achieve this to manually put the user's input data into
some sort of dumb object, put that dumb object into the session, and then
pass it as a PageParameter when heading back to B ?

No problem. ;-)
Yes, I have a lot to learn about wicket, but I know a lot more than I did
a
few days ago, and I like it so far.
Great!
In my particular case, the page in question is the HomePage, so, since
the
user has already been there on her way to Page2, I suppose I will always
need to create a new instance if I want to show an alert (for example) as
the HomePage is visited from Page2's submit (eg user saved some data
entered
on a Page2 form by hitting submit).
I acheived this, albeit by dubious methods (as you kindly pointed out),
by
including an alert in the head of the HomePage if the constructor that
takes a message (eg HomePage(String successMessage)) is called using a
StringHeaderContributor.
I suppose I need to review this.
On the other hand, it is still a useful learning exercise, either way,
and I
will now study your post in detail before I try again, cheers.
If you wish, you can pass the home page into your Page2.
add(new Link(someId) {
public void onClick() {
setResponsePage(new Page2(HomePage.this));
}
});
And take the Page arg in Page2's constructor.
That way, you have a reference to it, and can link back to that.
It's probably better to do status alert type stuff using Wicket's
FeedbackPanel (if it's for a form) or via some other Session-based
mechanism, though.
Have fun playing.

Al
