RE: Control panels through Ajax
I´m really new to web programming, so how should that solve my Problem? If I
got it right the mediator does only know the colleagues which would be Panels
in my case. But the methods of these colleague Panels are hidden because of
inheritance (myPanel is child of Panel). Could you describe this solution a
bit deeper?
In general terms:
class A extends Panel {
private ABMediator mediator;
//...
add(new AjaxLinkVoid(theLink) {
public void onClick(AjaxRequestTarget target) {
mediator.callIntoB(target);
});
}
}
class B extends Panel {
// ...
public methodForTheMediator(AjaxRequestTarget target) {
// Do something
target.addComponent(someBComponent);
}
}
class ABMediator {
private A a;
private B b;
// ...
public void callIntoB(AjaxRequestTarget target) {
b. methodForTheMediator(target);
}
}
You could also leave out passing around the target and instead get it using
AjaxRequestTarget.get(). As you see, the method invoked on B is public in this
case.

A HTML input of type=reset will by default do nothing server-side but just reset input fields of a form to the initial values. As an alternative you could have a Wicket Button which resets the form inputs (remember to turn off default form processing).

It seems you want to use getConvertedInput(). Going via the model to get the
converted value is just a detour when you are in a validator. If you push data
to the model and then decide it is invalid, then your model will have invalid
data, and if that is acceptable, what role does the validator fill then? You
might as well do your checks in onSubmit() at that point...

1) Why do you use immediate-child selectors (involving ) instead of just child selectors (without the )? The selector .custom-component-class header will work. 2) wicket namespace tags are removed in deployment mode (or if you tell markup settings to strip them), so wicket:child will disappear the same way wicket:panel does. 3) Look into approaches that involve less subclassing, the real problem is that design-time you will not see the entire HTML template as long as fractions are spread around due to child class markup.

RE: Wicket Philosophy/Best Practice
I tell people that I think you should let your Model and Model backing object control the look and feel/display/content of your components. Even visibility should be delegated to the model or model object and not set by the component. Am I wrong here? Yes. :) The model should NOT care about the view, or even know one is there; a controller is supposed to manipulate the model, any view (if any) should just get the value from there and do any necessary formatting (e.g. using a converter to/from textual representation). For instance, why should a Model need to know the locale of a web user to produce a correct representation?

For more complex cases you can either try passing a JSON representation of an object, or use cross-context features in the container (e.g. in Tomcat you put a property in the context.xml file for the app to enable it) by getting the other application's ServletContext by path. If they are just going to share information in a manner not limited to the request, try putting it into JNDI from application A then picking it up in application B.

SV: SV: Multiple wicket applications in a single WAR
I don't think it is a good idea to have multiple applications in one war. Wicket stores static state in ThreadLocals (Application, Session, etc.). The ThreadLocal objects are static, yes, but the actual objects stored there are per thread and thus not static. All apps in the same war share the same ClassLoader and thus the same static ThreadLocal instances. There might be circumstances when the state somehow gets messed up. If one thread can get at objects belonging to a different thread that would not be a circumstance but a serious bug. I'm sure this is the source of your problems. So, either go for one app for all users or create two separate war files. The Application instance is shared between all users, but in this case there is no user state in it, the difference is which Session class is used for factorizing the user Session, and which Pages are mounted (again, for factory purposes). - Tor Iver - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

SV: Painting a ListView in Ajax via a transparent container fails
I don't know what you mean with transparent but ofcourse you cannot repaint invisible things. A transparent container is one that appears in the markup and in the code but which returns true for isTransparentResolver(). It's not invisible but is not part of the explicit hierarchy. An example of such a container is the one represented by the wicket:enclosure tag. I.e. if you have container A, add a transparent container B to A, and in the markup have a hierarchy of A - B - C, you would add C to A instead of B: The code relating to the hierarchy of A will ignore B, but at runtime Wicket knows that B sits between A and C. - Tor Iver - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
SV: Painting a ListView in Ajax via a transparent container fails
wicket:enclosure is not present if not visible (from browser perspective). So it cannot be repainted.

Anyway, my problem was solved by eliminating the transparent container and just paint the panel and feedback-panel. - Tor Iver - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
SV: Painting a ListView in Ajax via a transparent container fails
So this special component is designed to be aware of children components only at the rendering time ( working with the markupStream ) and not at the pre-rendering. As the ListView depends on pre-rendering logic, add an transparent resolved component in ajax request target has no effect because no children pre-rendering method will be invoked. Ah, that explains it! In this particular case the number of real top-level components is low enough that adding them explicitly is no big deal, so I now have an approach that seems to work. - Tor Iver - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
