How to pass object as parameter to popup window
Hi All, I'm fairly new to Wicket, so forgive me if my question sound silly. I've implemented a preview window by using bookmarkable page link and popup settings, very similar to Linkomatic from wicket examples: - PopupSettings popupSettings = new PopupSettings(PageMap.forName(mypopuppagemap)).setHeight( 500).setWidth(500); add(new BookmarkablePageLink(popupLink, MyPage.class).setPopupSettings(popupSettings)); However, the issue that I face is that I need to pass an object as parameter to MyPage, as this object is a class containing validated input values from UI but not been persisted to db. What would be the best way to implement this? Thanks. Cheers

problem with WicketTester to load template

How do I provide digit-only IDs to make childs safe?
Hi, I'm a new Wicket user who is also getting familiar with the GMap2 module from wicket-stuff. I'm using the geocode example as a basis for creating a form which allows you to search for a location and set the map viewport to display it: https://wicket-stuff.svn.sourceforge.net/svnroot/wicket-stuff/trunk/wicketstuff-core/gmap2-parent/gmap2-examples/src/main/java/wicket/contrib/examples/gmap/geocode/ The code works, but every time I search for a place I get a warning: WARN - AbstractRepeater - Child component of repeater org.apache.wicket.markup.repeater.RepeatingView:content has a non-safe child id of [STRING_SEARCHED]. Safe child ids must be composed of digits only. The [STRING_SEARCHED] is whatever I typed in the text field (e.g. Barcelona, Spain or Athens, Greece). So apparently, GMap2 sets an ID somewhere using the text field's value, violating some Wicket expectation that such IDs should be composed using digits only.

How to centrally handle common exceptions from the databsae layer?
I am hoping to understand how to write a good wicket app regarding handling
exceptions from the databsae layer?
For a wickt form, I can have the following to handle user submission:
@Override
protected void onSubmit() {
User u = getModelObject();
userDao.saveUser(u);
setResponsePage(Results.class);
}
For a wikcet web app, I can have many forms.
But what is the best way to handle common database exceptions such as foreign
key constraint violation, larger than a column width, etc. and displaying
meaningful error messages? I could easily add try/catch around userDao#saveUser
to handle them, but that would be bad in terms of code replication and
maintenance. It may be good to handle in a central place.
How do you deal with this issue in your wicket apps?
Thanks for input!
Best.

Scalability
Hi Wicketers, 1) I need to build a system which can perform -6000 different users per day and -200 concurent users The software used: wicket postgresql (mainly read operations) hibernate jms At the beginning there will be 2 computers (I prefer horizontal scalability). What would be your advice for the hardware (hard drive will be 10.000 RPM). -processor ? -ram 2) Also I would appreciate your advice for the server: I have the choice for the server: Tomcat + a JMS implementation like HornetQ, or Jboss Application Server. I hesitate between the 2 solutions, as I don't need EJBs, but we never know !!! . Have you any advice ?

If you don't need EJBs (and who would, I've always steered clear from them and never regretted it), than don't worry about it. In the unlikely case you ever do, just address it then by swapping out your app server. Write your software generically enough so that you don't depend on a single one. If you know you need MQ and you want management of it integrated in your application server, JBoss is worth considering. Also look at Glassfish while you're at it.

Re: Recover from session expiration ?
Have you seen jolira-tools? It was mentioned here on the mailing list recently.

Re: Recover from session expiration ?

Re: How do I provide digit-only IDs to make childs safe?
Hi Alexandros, it's just that the example uses the location's name as an id for a label shown as content in a GInfoWindowTab. See the following line in the example: new GInfoWindowTab(address, new Label(*address*, address)) The label will end up inside a repeater which is complaining about the id.

Re: Wicket and JEE6
Just have a look at https://wamblee.org/svn/public/wicket-cdi The main thing I did was to make the injection and caching stuff completely independent of wicket and I made some arrangements to still allow unit tests where you can inject different things from the defaults. In particular, I think you can incorporate the InjectorCache in your design and it would also be good to make the injection support independent of wicket. Basically, the org.wamblee.cdi package tries to provide a simple and efficient injection api (bean manager api is too general and too verbose for most purposes)
