Re: [Wicket-user] Could not find root ajax-response element with AjaxFormSubmitBehavior+ browser back botton
I trace the code and found the cause is some AjaxBehavior calling AbstractAjaxBehavior.getCallbackScript(boolean recordPageVersion, boolean onlyTargetActivePage) with onlyTargetActivePage=true. by this, ajax behavior is only actived in latest access page. I check core component and those AjaxFormSubmitBehavior, AjaxSelfUpdatingTimerBehavior, and AjaxFormComponentUpdatingBehavior are setting flag as true and don't have alternative option. Is there any concern why these behaviors have to use latest access page ?

[Wicket-user] DropDownChoice inconsistent value returned
Hi,
I’m having some trouble getting a DropDownChoice component to bind the value
I want to the supplied model and could use some help. More specifically,
I’ve created a custom dropdown by extending DropDownChoice (see below)
because I need to use a custom value for the hidden value attribute in the
HTML option tag and a more readable version of that value for display. The
hidden value needs to be bound to the model, not the display value.
Everything renders and binds to the model properly the first time the user
fills out and submits the form. The problem appears when the user returns to
the form (which will display his/her previous choices) and tries to update
the selection in the dropdown. For some reason unknown to me the when the
user updates the form, the value from the dropdown that is passed to the
model is the (undesired) display value instead of the (desired) hidden value
attribute data that is passed to it the first time the form is submitted.
Thoughts?
Thanks,
Peter
Package…
Import…
public class DateDropDownChoice extends DropDownChoice implements
Serializable {
// values to go into the hidden value attribute in the HTML option tag
// AND to go into the model/database
final static private String[] ids =
{20031,20032,20033,20034,20041,…};
// values to be displayed in the dropdown
final static private String[] values ={2003, Fall,2003,
Winter,2003, Spring,2003, Summer,2004, Fall,…};
public DateDropDownChoice(String id, IModel iModel) {
super(id, iModel);
ArrayList choices = new ArrayList();
int i = 0;
for(;iids.length;i++)
// choices.add(new DateChoice(ids[i],values[i]));
choices.add(values[i]);
this.setChoices(choices);
this.setChoiceRenderer(new CustomChoiceRenderer());
}
class CustomChoiceRenderer implements IChoiceRenderer{
public Object getDisplayValue(Object obj) {
return obj.toString();
}
public String getIdValue(Object obj, int i) {
/**
* An i of -1 is passed when a previous selection
* has been made and is stored, so just return the obj string
value
* because it is a properly stored value such as 20063 from
the previous submission
*
* An i 0 means that I need to look up the
appropriate/corresponding
* value from the ids array.
*
*/
String returnVal = i0?obj.toString():ids[i];
System.out.println(returnVal: +returnVal+ :: ID:: +i);
return returnVal;
}
}
}
And then in my form I set up the custom dropdown.
//…
DateDropDownChoice studentSince =
new DateDropDownChoice(studentSince,new
PropertyModel(iModel,studentSince));
add(studentSince);
//…

Re: [Wicket-user] DropDownChoice inconsistent value returned
dropdownchoice works like this:
DropDownChoiceT(String id, IModelT model, IModelListT choices,
IChoiceRendererT)
but from your description i see you are using it like this:
DropDownChoiceString(String id, IModelString, IModelListDateChoice,
IChoiceRendererDateChoice)
i take it studentSince is a String?
DropDownChoice works with objects, not their id values. so it is one of the
objects you pass in as choices that gets put into the model. looks like you
are putting in DateChoice objects into the choices, but your model prefers a
string.
it probably works the first time because DateChoice.toString() returns the
id?
what you want is something like this:
final MapString,String codeToText=new LinkedHashMap();
codeToText.put(20041, 2004,Fall);
...
ListString keys=new ArrayListSTring();
keys.addall(codeToText.keyset());
IChoiceRenderer renderer=new IChoiceRenderer() {
getid(Obect o) { return o.toString(); }
getValue(Object o) { return codeToText.get(o.toString()); }
}
new DropDownChoice(foo, new PropertyModel(...), keys, renderer);
another approach would be to write a model that does the translation between
string and datechoice. use whatever route appeals to you more.

Re: [Wicket-user] wicket presentation
Those dropdowns should be updated without troubles. Why do you need
the wantOnSelectionChangedNotifications there? Did you try removing
the overrides of these methods? As far as I can see you're not doing
anything useful with them.

However upon doing this I've stumbled into something I find odd, in the
below code the label called model are not updatet when it's model are
changed, I got the same problem with the dropdown, I fixed that by calling
the dropdown.modelchanged() method. But is it really necessary to call
modelchanged? I saw the ajax example which is almost identical to this does
not call modelchanged.
public class IndexPage extends WebPage {

Subject: [Wicket-user] wicket presentation
Hi im doing a wicket presentation for our consultants team, on this first
teaser I have about ten minutes.
I plan to talk something about markup inheritance(the stuff with panels and
borders, which are very nice), and the POJO concept.
Also wickets model concept and that you don't have to think about the
tedious tasks like printing html and setting the correct radio to be
selected. I guess that part will be a big eye opener for some of themJ
Which features should I show?
The crowd will maximum have knowledge of struts or simple jsp pages.
Regards Nino

[Wicket-user] API break for 1.3 and 2.0: Session constructor
I just committed an API for 1.3 and 2.0. For those of you working on
the 1.x branch or trunk, and you're using a custom session, you'll
have to fix this:
* Add a Request argument to your custom session object, e.g.
public class MySession extends WebSession {
protected MySession(final WebApplication application, Request request)
* Method WebApplication#newSession is made final and will be removed
in the near future. Instead, use WebApplication#newSession. Big chance
you don't have to do anything as this method was already available and
you might have overriden getSessionFactory rather than the method in
WebApplication.

Eelco
