[Wicket-user] beginners question: wicket and sessions
Hi,
i have a small
problem in understanding the way sessions are used in wicket. Whenever i access
any new wicket app (even HelloWorld) it gives me a SID, so i know i have a (http
servlet) session. However, using the http.session is not the wicket way, and the
wiki just tells:
Custom Sessions
The wicket way of storing objects in your session is by extending the
wicket session. For example if you want to store some kind of user object in
your session, you would create a getter and setter for it in your custom wicket
session: public class MySession extends WebSession {
public MySession(WebApplication application) {
super(application);
}
private String myAttribute;
// ... getters and setters
}But why do i have to explicitly do the getters and setters for each thing i want to have remembered?? -or did i get sth. wrong here???Best Regards,KorbinianPS: a little bit off-topic, but im also working myself into ejb3 a bit and i wondered, if i have a stateful sessionBean (e.g. a ShoppingCart) and i call the bean in any wicket page and set a product into it,how will be remembered to what session the Cart is attached to? - do i have to keep the connection to the specific bean open all the time or does the beancontainer take care for that ???

Re: [Wicket-user] A problem with BookmarkablePageLink
Hmm when you specify the root AND the wicket servlet mapped to /* then yessomething goes wrong. I fixed this for 1.2.2 but this is not really the recommended approacheYou can run in the root just fine but don't specify the wicket servlet to /*
That is only the best way for 2.0 where we have a filter.johanOn 8/12/06, itsliang [EMAIL PROTECTED]

example to try out BookmarkablePageLink. In exmaple, you can find three webpages. In each web page, there are two links that can be used to link to theother two pages. And I only mount my second page as a BookmarkablePage.
When I deploy the example to the root of my tomcat 5.5 (by extracting thewar file to $TOMCAT$/webapps/ROOT/), which means I can access my app fromhttp://localhost:8080/
, the link in my second web page didn't work properly.However, if I not deploy the example to the root of my tomcat, let's sayhttp://localhost:8080/TestBookmarkable/
for example, then everything workswell without any problem.Is this a bug of wicket? or did I implement my example in the wrong way? Thewar file and source code of my example can be found here:

Re: [Wicket-user] Form-question
What I want the following code to do is to iterate all propertyTypes
and create or lookup the appropriate property on my Person-object and
create a TextField for each one.
I've defined a model for the propertyTypes and a model for a
TeamPerson-object which contains my Person.
Everything works fine except that the setObject(Component c, Object o)
in PersonPropertyModel is never called.
On screen the form renders and look fine but nothing gets written back.
Would appreciate another pair of eyes on this.
IModel propertyTypes = new LoadableDetachableModel() {
protected Object load() {
return userService.allPropertyTypes();
}
};
ListView dynamicProperties = new
ListView(dynamicProperties, propertyTypes) {
protected void populateItem(ListItem item) {
TextField valueField = new TextField(value);
valueField.setOutputMarkupId(true);
FormComponentFeedbackBorder feedbackBorder = new
FormComponentFeedbackBorder(feedback);
feedbackBorder.setRenderBodyOnly(true);
feedbackBorder.add(valueField);
item.add(feedbackBorder);
Label label = new Label(propertyType.name);
label.add(new AttributeModifier(for, true, new
Model(valueField.getId(;
item.add(label);
}
protected IModel getListItemModel(IModel
listViewModel, int index) {
PropertyType pt = (PropertyType)
super.getListItemModel(listViewModel, index).getObject(null);
return new CompoundPropertyModel(new
PersonPropertyModel(EditTeamPersonPanel.this.getModel(), pt));
}
}.setReuseItems(true);

if (pp == null) {

Re: [Wicket-user] beginners question: wicket and sessions
wicket's session object is stored inside http session. the getters and setters there are to make your code cleaner then using http session's map:object-object which is pretty ugly - so instead you use typesafe getters and setters. and as johan pointed out whenever you modify wicket's session object you have to call dirty() on it - this call triggers replication so the session is updated across the cluster if you have one.

No you dont have to have getters and setters but that is just a nice approache.How else would you get your data?And it is better to have a setter if the data can be changed because in the set you can call: dirty()
which is for us a trigger to reset our session object in the the http session object so that it knows that the session object is changed.johan

The two links forward the user to the same page but with different information to display. Here is what I do: 1. open the home page 2. right-click on one link and open the link in a new window 3. click on another link 4. refresh the window opened by step 2 After step 3, the two windows show different content. After step 4, the window opened in step 2 shows the same content as the main window. What am I doing wrong? What are the conditions for this to work? Cheers Erik PS.

Re: [Wicket-user] Two feedback panels on one page
well, its not the default because this is a tiny subset of what wicket's feedback system is capable of.now if it is a common usecase in your app you can craete a BoundedFeedbackPanel given the code i gave you previously. its a 10 line component that you can then reuse in your app - this is the power of wicket. we give you the tools that make it easy to adapt the functionality to many situations. if we started to provide impls for all common usecases the api would be too big and you would have a hard time finding what you needed anyways.

Re: [Wicket-user] DatePicker with SimpleDateFormat
Johan,
Thanks for the help. Settled on this:

final SimpleDateFormat sdf = new SimpleDateFormat(MM/yy);
conv.setDateFormat(Locale.getDefault(), sdf);
TextField exp = new RequiredTextField(expiration) {
public IConverter getConverter() {
return new SimpleConverterAdapter() {
public String toString(Object value) {
return value != null ? sdf.format(value) : null;
}
public Object toObject(String value) {
try {
return sdf.parse(value.toString());
} catch (Exception e) {
throw new ConversionException(' + value
+ ' is not a valid Date);
}
}
};
}
};
DatePicker picker = new DatePicker(expirationDatePicker, exp);
picker.setDateConverter(conv);
add(exp);
add(picker);

That way it is only used to format the string to the screen.
The dateformatter is used to get the format out and javascript
dateformat is generated based on that
That dateformatter should also be used by the textfield itself to
handle the formatting both ways.
So override the getConverter() of the exp textfield and return als
your converter (that has to work 2 ways then!)
